Ozone and Toxicity

Ozone is found in gaseous form as a natural ingredient of the earth's atmosphere. Some of the chemical and
physical properties of ozone are as follows:

Terms

Properties of Ozone (O3)

Molecule Weight

47.9982 g/g-mol

Boiling Point

-119  0.3 °C

Melting Point

-192.7  0.2 °C

Exposure to even low concentrations of ozone can be damaging to delicate nasal, bronchial and pulmonary
membrane. Symptoms of acute ozone toxification appear at a concentration of about 1 ppm by volume. The
type and severity of symptoms depend on the concentration and duration of exposure. In mild cases and in
the early phases of severe cases, symptoms will include one or more of the following:

 Irritation or burning of the eyes, nose or throat
 Lassitude
 Frontal headache
 Sensation of sub-sternal pressure
 Constriction or oppression
 Acid taste in mouth
 Anorexia

In more severe cases, the symptoms may include dyspnoea, cough, choking sensation, tachycardia, vertigo,
lowering of blood pressure, severe cramping, chest pain, and generalized body pain. Pulmonary oedema may
develop with delayed onset, usually one or more hours after exposure.

Following severe acute ozone toxification, recovery is slow. In the few severe human cases reported, 10 -14
days of hospitalization were required. In these cases, minimal residual symptoms were present for as long as
9 months, but all cases eventually recovered completely.

The 1983 ACGIH has recommended a Threshold Limit Value (TLV) of 0.1 ppm (0.2 mg/m3) for ozone. The
safe level for short human exposure to concentrations of ozone in excess of 0.1 ppm (Threshold Limit Value)
is not known with certainty. The atmospheric concentration immediately hazardous to life is likewise not
known, but inhalation of 50 ppm for 30 minutes would probably be fatal. The odor threshold of ozone for a
normal person is 0.01 - 0.02 ppm by volume in air.

First Aid Treatment

Move the victim to an uncontaminated atmosphere. Control restlessness and pain by the administration of
sedatives and anodynes orally. Severe cases may require subcutaneous injections of small doses of
meperidine hydrochloride (Demerol) for relief of pain. Give oxygen inhalation by facemask when the acute
symptoms have subsided. Severe cases require hospitalization since deferred pulmonary oedema may
develop.

1.4.2 Carrier Gas and Exhaust Gas Precautions

BioTector uses oxygen (O2) gas as the carrier gas during its operation. The oxygen gas must be free of
carbon dioxide (CO2) and nitrogen (N2) gases. The average rate of oxygen consumption in BioTector is 22
L/hour (367 ml/min). Carbon dioxide filtered air, carbon dioxide and nitrogen contaminated oxygen gas are not
suitable for BioTector TOC TN analyzer. When handling oxygen:

 The same precautions, which are required for any high pressure or compressed gas system, must be

taken to avoid accidents.

 Comply with all local and national regulations and/or manufacturer's recommendations and guidelines

when working with oxygen.

 If oxygen cylinders are used, they must be transferred safely using appropriate equipment (e.g. carts,

hand trucks etc.)

 If oxygen cylinders are used, they should be labeled clearly for identification and well secured for

storage and transport.

 Avoid the use of extensive number of adaptors and couplers.
 Do not allow oxygen to come in direct contact with grease, oil, fat, and other combustible materials. If

uncertain how to handle oxygen cylinders and high concentration oxygen, contact your local oxygen
manufacturer.

 If oxygen concentrator is used, take precautions to avoid a fire in the area of the concentrator, install

the concentrator only in a well ventilated area and comply with all local and national regulations.

Vent waste gases to atmosphere or to a well ventilated area making the necessary connections on system
exhaust. Under normal operating conditions, waste gases will contain oxygen, traces of carbon dioxide and
the traces of volatiles/gases which may exist in the sample stream. Under abnormal conditions, the waste
gases may contain traces of ozone.

1.4.2 Précautions relatives au gaz porteur et d'échappement

Pour son fonctionnement, BioTector emploie de l’oxygène (O2) comme gaz porteur. L’oxygène ne doit
comporter aucun gaz carbonique (CO2) ni d’azote (N2). Le taux moyen de consommation d’oxygène du
BioTector est de 22L/heure (367 ml/min). L’analyseur BioTector TOC TN ne tolère pas l’air filtré de gaz
carbonique ni l'oxygène contaminé de gaz carbonique et d'azote. À la manipulation de l’oxygène:

 Afin d’éviter les accidents, prendre les mêmes précautions que pour tout appareil à haute pression ou

gaz comprimé.

 Pour toute opération avec de l’oxygène, se conformer aux règlementations locales et nationales et/ou

aux recommandations et consignes du fabricant.

 S’ils sont employés, les cylindres d’oxygène doivent être transportés en toute sécurité à l’aide du

matériel approprié (chariots, diables, etc.)

 S’ils sont employés, les cylindres d’oxygène doivent être clairement étiquetés pour en permettre

l’identification et bien arrimés pour leur stockage et leur transport.

 Éviter d’utiliser un nombre élevé d’adaptateurs et de dispositifs de couplage.
 Ne pas laisser l’oxygène entrer en contact direct avec de la graisse, de l’huile, des matières grasses

ou d’autres matières combustibles. Veuillez contacter votre fabricant local d’oxygène si vous avez
des doutes sur la manière de manipuler les cylindres d’oxygène et l’oxygène de haute concentration.

 Dans le cas où un concentrateur est employé, prendre les précautions nécessaires pour éviter un

incendie dans la zone du concentrateur, n’installer le concentrateur que dans un endroit bien ventilé

et se conformer aux règlementations locales et nationales.

Évacuer les gaz usés dans l’atmosphère ou dans un endroit bien ventilé en réalisant les branchements
voulus sur l'échappement de l’appareil. Dans des conditions normales de fonctionnement, les gaz usés
contiennent de l’oxygène, des traces de gaz carbonique et des traces de composants volatiles/gaz qui

Screen Layout and System Message Priority

The system status messages are displayed on the top left hand side of the Reaction Data and Reagent
Status screens. On most other screens, only the screen name is displayed in this location.

System status messages are displayed in the following priority:

1. SYSTEM MAINTENANCE – the BioTector is in Maintenance mode, activated by the maintenance
switch.

2. SYSTEM FAULT – There is a fault on the BioTector. System is stopped.

3. SYSTEM WARNING – There is a warning on the BioTector. System is running.

4. SYSTEM NOTE – There is a notification on the BioTector. System is running.

5. SYSTEM CALIBRATION – The BioTector is calibrating. This could be Span Calibration, Span Check,
Zero Calibration or Zero Check.

6. System operation status. This could be one of either:

 SYSTEM RUNNING – system is running.
 SYSTEM STOPPED – system has been stopped by a fault or from the keypad.
 REMOTE STANDBY – system has been put into standby mode remotely. System has stopped

analyzing.

The BioTector time and date is displayed on the top right side of each screen. When a
fault/warning/notification is logged in the system, a FAULT LOGGED message will alternate with the time/date
in this location until the fault/warning/notification has been corrected.

Changing most system settings are prevented when the BioTector is running.

The BioTector has separate passwords for all levels/security domains, which are operation, calibration
diagnostics, commissioning, system configuration and hardware configuration.

These passwords are programmable, and if a password has been set up for a particular level, then it must be
entered before the BioTector will grant access to the password-protected security domains.

Use of a higher-level password also allows access to lower levels/domains.

2.1 Operation Menu

Operation Menu Diagram

Operation menu allows the user to start and stop the analyzer. Menus related to system operation are also
accessed using this menu.

Start Stop

The user can Start or Stop the BioTector using the Start Stop menu.

1. Remote Standby. Remote Standby is an optional function, which is activated from Input 19 (by default) on

the Signal PCB (e.g. from a flow switch). A “REMOTE STANDBY” message is displayed on the top left
corner of the main Reaction Data screen to indicate that the BioTector is in remote standby state. When
remote standby signal is activated, the BioTector stops analyzing. All menu access and operational
functions remain as for BioTector normal running state. The BioTector runs one standby reaction every 24
hours, at the time programmed for the Pressure/Flow Test (at 08:15 AM by default). Sample is not taken
during the remote standby reaction (only acid and base reagents are used). This reaction is tagged as “RS”
(Remote Standby) in the system reaction archive. The 4-20mA signal or other output devices are not
updated. When remote standby signal is deactivated, the BioTector starts analyzing.

When remote standby signal is activated, the “Finish & Stop” or “Emergency Stop” must be selected before
using such functions as Install New Reagents, Zero and Span Calibrations, Process Tests etc. If the
BioTector is stopped using the “Finish & Stop” or “Emergency Stop” functions or automatically by a system
fault, it will not be possible to start the BioTector by the removal of the remote standby signal. The “Start”
function must be used to re-start the BioTector. When BioTector is started while the remote standby signal
is activated, BioTector goes into remote standby state. The manual grab sample analysis can be carried out
normally using the Manual Program menu when the BioTector is in remote standby state.

Maintenance should only be carried out when “SYSTEM STOPPED” message

is displayed on the top left corner of the main Reaction Data screen or when
the system is powered down. When “REMOTE STANDBY” or “SYSTEM

RUNNING” message is displayed on the screen, stop the BioTector using the
“Finish & Stop” or “Emergency Stop” function.

Caution

Page 24

2. Start. This function starts the BioTector. When BioTector is started, the multi-stream operation sequence (if

programmed) is reset. BioTector performs Ozone Purge, Pressure/Flow Test, Reactor Purge and Analyzer
Purge sequences automatically before starting its analysis. Ozone Purge sequence purges any residual
ozone through the ozone destructor. Pressure/Flow Test sequence confirm that there is no gas leak and
there is no gas flow restriction in the BioTector. Reactor Purge sequence purges any liquid from the reactor
through the Sample Out Valve. Analyzer Purge sequence purges any CO2 gas from the CO2 Analyzer
through the Exhaust Valve.

3. Finish & Stop. When this function is activated from the keyboard, the BioTector stops as soon as its

present reaction is completed. An “*” is displayed to let the operator know the function has been activated.

4. Emergency Stop. When this function is activated the BioTector cancels the execution of the present

reaction and quickly stops operation after the Ozone Purge, Reactor Purge and CO2 Analyzer Purge
sequences. The Emergency Stop has highest priority, and always overrules the “Finish & Stop” function.

Quick Startup Function: During maintenance, system testing etc. it may be
necessary to quickly start and stop the BioTector to check various parameters.
Pressing the ENTER key for the “Start”, when the RIGHT ARROW key is also
pressed, bypasses the Pressure/Flow Test sequence, ensuring a quick startup.

When the quick startup function is used, system will log a “28_NO PRESSURE
TEST” warning in the fault archive and will start operation. The same warning will
also be logged, when the BioTector is started from the Reagents Setup, Manual
Program and Calibration menus using this function.

Reagents Setup

This menu allows the user to access the Reagent menus.

1. Install New Reagents. Menu used to install and prime the reagents in the BioTector. Any “85_Reagents
Low” and “20_No Reagents” warnings and notifications can also be reset in this menu.

2. Purge Reagents & Zero. Menu used to purge the reagents, and carryout a zero calibration cycle.

The install new reagents procedure is an automatic procedure for installing new reagents, setting the zero
offset by Zero Calibration cycle, setting the reaction check levels and checking the span by Span Calibration
or Span Check cycles. Span Calibration or Span Check cycles are part of the Install New reagents sequence
if SPAN CALIBRATION or SPAN CHECK is activated in New Reagents Program menu. The basic Zero
Check/Calibration and Span Check/Calibration parameters (operation ranges, number of reactions, standard
solution concentrations etc.) are programmed in Zero Calibration and Span Calibration menus respectively.
The comprehensive Zero Check/Calibration and Span Check/Calibration parameters are programmed in Zero
Program and Span Program menus respectively.

Page 26

To run the Install New Reagents cycle, the BioTector must be stopped. Confirm that all or the corresponding
new reagents have been installed on the BioTector, for instance for acid reagent, select New Acid Connected,
and press the ENTER key. A tick mark will appear as confirmation that the new acid has been connected.
Note that when one or more reagent volumes are updated in Reagents Monitor menu, system automatically
resets the new reagents volumes in this menu and also updates the figures displayed in the main Reagents
Status screen.

All reagents volumes can be reset while system is running. This function allows the user to top up the
reagents, preferably HCl Water (if installed in systems built with FMI Heavy Duty Circulation Pump), TN
Cleaning Solution and DI Water, without stopping the system. However, when Acid and/or Base are replaced
or topped up, system requires a new Zero Calibration cycle. A “ZERO CALIBRATION REQUIRED” warning
will be displayed on the screen when RESET ACID MONITOR and/or RESET BASE MONITOR are selected.
Therefore, it is strongly recommended to stop the BioTector and activate the Start New Reagent Cycle or to
run the Zero Calibration cycle using the Zero Calibration menu. It is important that Zero Water (DI Water) is

connected to BioTector’s Zero Water port before the Install New Reagent cycle is started. Unlike BioTector

TOC analyzers, in BioTector TOC TN analyzers, Zero Water is required so that the correct zero offset (Zero
Adjust) values are set for TN analysis. Failure to do so may have an impact on system zero response and the
analysis results.

When all or the necessary reagents have been confirmed to be connected and reset in this menu, and when
Start New Reagent Cycle is selected, the Install New Reagents cycle will be executed. It is the responsibility
of the user to make sure that all reagent volumes are programmed correctly in Reagents Monitor menu, the
reset of the reagents monitoring are carried out correctly in Install New Reagents menu and finally if
necessary the Zero Calibration cycle is activated either with the Start New Reagent Cycle function in Install
New Reagents menu or with the Run Zero Calibration function in Zero Calibration menu.

The Install New Reagents cycle consists of the following steps:

1. Reagent Purge: System purges and fills all reagent lines with the new reagents.

2. Zero Calibration: The Zero Adjust (zero offset) level is set for all analysis ranges, and the Reaction

Check level for TOC is updated (if the CO2 LEVEL is programmed as AUTO in Reaction Check
menu).

3. If Span Calibration or Span Check is activated in New Reagents Program menu, a Span Calibration

or Span Check is carried out.

Once the procedure is completed the BioTector either stops or returns online, depending on the programmed
setting of AUTOMATIC RE-START in New Reagents Program menu.

Purge Reagents & Zero

The Purge Reagents & Zero function is an automatic procedure to purge the reagents, to set the zero offset
and to set the reaction check levels in the BioTector. The program settings for the Reagent Purge are set up
in the Reagents Purge menu.

1. Purge Reagents & Zero. This option allows the user to run the Purge Reagents & Zero cycle.

System Range Data

This menu displays the system specific analysis range data for all measured components (e.g. TIC, TOC, TN,
etc.). BioTector can be calibrated with up to 3 analysis ranges for each measured component. When a
specific component of a sample (e.g. TOC) is measured at a specific range (e.g. Range 2), the analysis of
any other components (e.g. TN etc.) of the sample are also carried out at the same analysis range.

Manual Program menu allows the user to run system in manual operation mode in order to analyze
samples/standards or a sequence of samples/standards manually. This is achieved by one or a set of manual
valves installed in the system. The manual analysis sequence can be started at the end of the current
reaction, or at a time set by the user. When the manual sequence is complete, the system can be
programmed to return online automatically. Note that all cleaning cycle, pressure/flow tests, zero or span
cycles are interrupted by the manual operation mode. The Sample Pump reverse operation is also disabled
during the manual operation mode by default, unless a Manual Bypass Valve is installed in the system and
the REVERSE time is programmed for the corresponding Manual Valve in Sample Pump menu. All items in
this menu can be modified when the BioTector is running unless:

- No manual valves have been defined in the Output Devices menu.

- The manual mode is currently running.

- The manual mode is scheduled to start when the current reaction is completed.

Note that the Manual mode always starts at the first programmed valve, and works its way down the
programmed sequence.

1. Run After Next Reaction. To start the manual operation mode sequence after the next reaction the

BioTector is currently running, press the ENTER key at this menu item. An “*” will indicate that this

function has been selected. If the BioTector is stopped, then the Manual mode starts immediately. To
deactivate this function before the manual operation mode has started, press the ENTER key again, or
activate an alternative function. In systems built with the remote control of Manual Program option, the
remote signal (Manual Mode Trigger from Input 7) activates the Run After Next Reaction function.

2. Run After 00:00. Similar to menu option 1 above, but the manual operation mode starts after the
programmed time.

3. Return to On-line Sampling. This menu item allows the user to specify whether the BioTector should
stop or return to online monitoring when the manual operation sequence is complete.

4. Reset Manual Program. Use this function to reset all the programmed settings to their default values.

6. - 30. Manual. In order to analyze one or a number of samples/standards using the manual operation mode,

first connect the sample/standard to the manual port/s outside the BioTector. Then, select the
corresponding Manual Valve in this menu (the first setting). Then, enter the number of samples (number
of analysis reactions) to be taken through each Manual Valve (the second setting). Finally select the
correct analysis range (RANGE 1, 2 or 3) if the concentration levels of the sample/standard are known
(see System Range Data menu to view the available system ranges and to select the correct operation
range). If the concentration levels of the samples/standards are not known, select AUTO so that
BioTector can automatically select the optimum analysis range. When RANGE is programmed as AUTO,
a minimum of five analysis reactions is recommended (the second setting) so that BioTector can find the
optimum operation range with its automatic exceedance tracking function. When AUTO option is
selected, depending on analysis range and system response, the first two or three analysis results may
need to be discarded.

Page 28

Reaction Archive

The Reaction Archive holds information on TIC, TOC, TC, VOC, COD, BOD, TN, stream valve, reaction
range, start time and related analysis information for the last 9999 reactions. If the archive is full, then every
new reaction overwrites the oldest one in the archive. As the Reaction Archive contains 9999 events, the user
must first enter the date at which the viewing of the archive starts. The Enter Date menu allows the user to
specify the date of the first displayed reaction from the archive.

Each reaction record in the reaction archive contains:

- Start Time - reaction start time, which is displayed without seconds in this menu

- Date - reaction date

- Reaction Type - with the prefixes below:

S1 to S6: Reactions from stream 1 to stream 6.
M1 to M6: Reactions from manual sample stream 1 to manual stream 6.

√ Sample sensor detected the sample or there is no significant quantity of air

bubbles in the stream/manual grab sample lines.

x Sample sensor detected no sample or there is significant quantity of air

bubbles in the stream/manual grab sample lines. See Sample Status in Fault

Setup section for details.
CF: Full cleaning reaction.
RW: Reactor wash reaction.
RS: Remote standby reaction.
ZC: Zero calibration reaction.
ZK: Zero check reaction.
ZM: Manually input zero adjust.
SC: Span calibration reaction.
SK: Span check reaction.
SM: Manually input span adjust.
A1 to A6: 24 hours average result from stream 1 to stream 6.

The user can navigate through the displayed reactions individually by pressing the UP and DOWN keys each
time, or can navigate in steps of 10 reactions using the LEFT and RIGHT keys. Depending on system
analysis type (e.g. VOC, TC –TIC etc.) and system display options (e.g. COD and/or BOD) settings, BioTector
displays additional reaction data held on additional Reaction Archive screens. To access the screens, press
the ENTER key, and to return to the previous screen, press the ESCAPE key.

Fault Archive

In the Fault Archive menu, the user can view the last 99 faults/warnings logged in the system, confirm if the
faults/warnings are current or not, and acknowledge current faults/warnings. If the archive is full, then every
new faults/warnings overwrites the oldest one in the archive. The user can navigate through the displayed
reactions individually by pressing the UP and DOWN keys each time, or can navigate in steps of 10 reactions
using the LEFT and RIGHT keys.

The faults/warnings archive events are divided into three categories:

- Fault: Faults are categorized as events, which stop BioTector operation. The 4-20mA signals are set
to the fault level, and the fault relay is activated. The BioTector cannot be started unless the fault in
the archive has been acknowledged.

- Warning: Warning is a minor fault, which does not require the BioTector to stop. The 4-20mA signals
are not changed, only the fault relay is activated.

- Notification: A notification is and information (e.g. “86_Power Up”, “87_Service Time Reset” etc.)
displayed on the screen.

To acknowledge any current faults/warnings marked with an “*” in the archive, first identify and locate the
faults/warnings. See Section 9 Troubleshooting of System Faults and Warnings. Follow the necessary
troubleshooting procedures to solve the problem. Acknowledge the fault by pressing the ENTER key in the
Fault Archive menu. Please note that there are system faults (e.g. 05_Pressure Test Fail), which cannot be
acknowledged by the user. Such faults are reset and acknowledged automatically by the system when
system is started, when system is rebooted or when the fault condition is solved.

Page 29

Time & Date

This menu allows the system time and date to be set by the user. To change the system time or date (hours,
minutes, seconds, day, month and year), press the ENTER key, enter the new time and date and press the

When the time is changed, it is possible for the BioTector to automatically start up if the
new time is after the startup time for a scheduled task, for example the startup time for
a manual sample sequence in Manual Program menu.

Zero Calibration menu allows the user to enter the suggested Zero Adjust values, to start the Reagent Purge
cycle, to start the Zero Calibration and Zero Check cycles and to program the number of zero reactions run at
each range.

1.-6. TOC/TN Zero Adjust. The TOC/TN Zero Adjust is used to compensate any organic carbon and nitrogen
contamination in the Acid and Base reagents and any absorbed CO2 in the Base reagent. The Zero
Adjust values are generated automatically by the system for each range when the zero calibration cycle is
completed without any system warnings. Zero Calibration cycle is activated by selecting the RUN ZERO
CALIBRATION function in this menu.

The TOC Zero Adjust values are the Zero Offset values in mgC/l measured by the CO2 Analyzer. The TN
Zero Adjust values are the Zero Offset Absorbance values measured by the Photometer.

When a Zero Check cycle is run using the RUN ZERO CHECK function, the system only checks the zero

response at each range and displays the suggested Zero Adjust values in brackets “[ ]” for all ranges next

to the current Zero Adjust settings. When a Zero Check cycle is completed, if necessary the suggested
Zero Adjust values can be programmed manually by entering the corresponding suggested Zero Offset
values for each range (1, 2 and 3) for each parameter in this menu. When the Zero Adjust settings are
entered manually, system logs this information in the reaction archive with the prefix “ZM” (Zero Manual).
