Measuring
Principle
Photometrical
Detection of
Silica
The AMI Silitrace Ultra is a complete monitoring system for the automatic, continuous measurement of trace amounts of silica in ultra
pure water.
Dissolved silica in water is concentrated with the use of a RO (reversed osmosis) membrane followed by a photometrical detection
of silica.
The determination of silica is done by the photometric analysis of
molybdate blue at 815 nm.
Silica and ortho-phosphates react at low pH with ammonium molybdate to the yellow colored molybdosilic acid respectively molybdophosphoric acid. The molybdophosphoric acid is destroyed with
oxalic acid before the molybdosilic acid is reduced with iron-(II)-ammonium-sulfate to the heteropolyblue complex.
Especially the reaction speed of the first reaction step to the molybdosilic acid is relatively slow. It is the most time consuming part of
the whole reaction. As the reaction speed increases with increasing
temperature, it is time saving to heat up the sample. The AMI Silitrace therefore uses a thermostatic reaction chamber with a constant temperature of 45 °C.
At 45 °C the complete reaction only needs 150 s (2.5 min). Because the reaction time plays an important rule in the color development, the pump speed is adjusted constantly. Due to the
automatic heating and reaction time regulation a very high precision is achieved.

Feed spacer
The Carrcentrator acts as a mesh that holds back large molecules
such as silica and allows smaller molecules (water, Na, etc.) to
pass through. The membrane is rolled to obtain as many layers as
possible. Most of the water (permeate) flows through the membrane and only a small part forms the concentrate. The permeate
and the concentrate leave the module via two separate outlets.
The separation of permeate and concentrate needs a high flow
rate. As a minimum 100 l/h at 2 bar must be provided to press the
water through the membrane.
The aim of this measurement is to detect the silica in the concentrate and calculate it back to the feed water. Three points must be
taken into account:
Concentration factor: Distribution ratio between the total flow
and the concentrate flow.
Separation efficiency: Constant factor of 90%.
Background: Silica reading of the permeate. This reading is
the sum of the silica
– which is in the reagents and
– which passes the membrane.
The background is measured daily, the efficiency is fixed and the
concentration factor is changed constantly by the flows.

Product Description
The silica reading on the display is calculated as follows:
Where
Reading Concentrate = – Log
Fluidic The sample enters at the sample inlet [S] and flows through the
concentrator [Q]. The sample is split in a permeate and a concentrate outlet which are led to the flow cell high flow [J] (permeate)
and the flow cell low flow [I] (concentrate). The flow rate is measured with the flow meters attached to the flow cells [I] and [J].
The concentrate is connected to the 6-way valve [H] position 1, the
permeate to position 6. Excess sample overflows into the sample
outlet.
The peristaltic pump [O] sucks the concentrate from the 6-way
valve and pumps it into the reaction chamber [C]. The reaction
chamber is wrapped around a heating device. It has 4 inlets to allow dosing of the necessary reagents.
In the reaction chamber the sample is heated up to 45 °C, eliminating temperature deviations of the sample. In a first step Ammoniummolybdate [K] and sulfuric acid [L] are added, to form the
yellowish molybsilic acid and molybdophosphoric acid.
Afterwards the oxalic acid [M] is added to mask the molybdophosphoric complex. At last the reducing agent ammonium ferrous (II)
sulfate [N] is added. The color of the sample turns to blue. As silica
is only present in trace amounts, the blue color can not be seen.
Afterwards the colored sample flows into the thermostatic cuvette
[D] until it is filled completely. Now the intensity of the color is measured at 815 nm. The color development is proportional to the silica
concentration in the sample.
As the level of the sample in the cuvette increases, the sample
overflows into the siphon tube [F] and eventually the cuvette is
drained spontaneously through the siphon tube. The sample is led
via the aeration and drain tube [R] into the sample outlet.
Dosing, mixing and filling of the photometer are determined by the
rotating speed of the peristaltic pump [O]. This speed is adjusted
automatically and guarantees the correct timing of the measurement.

3.3. Mounting of Instrument Panel
The first part of this chapter describes the preparing and placing of
the instrument for use.
The instrument must only be installed by trained personnel.
Mount the instrument in vertical position.
For ease of operation mount it so that the display is at eye
level.
For the installation a kit containing the following installation
material is available:
– 4 Screws 8x60 mm
– 4 Dowels
– 4 Washers 8.4/24 mm
Mounting re-
quirements
Mount the
hollow profiles
The instrument is only intended for indoor installation.
For dimensions see Dimensions, p. 14.
Mount the hollow profiles [A] with the pipe clamps [B] facing to the
left side to a wall or a suitable support.
Install the instrument panel to the hollow profiles using the fixing
screws [C].

WARNING
Risk of electrical shock.
Do not perform any work on electrical components if the transmitter is switched on. Failure to follow safety instructions could
result in serious injury or death.
Always turn off AC power before manipulating electric parts.
Grounding requirements: Only operate the instrument from a
power outlet which has a ground connection.
Make sure the power specification of the instrument corre-
sponds to the power on site.

WARNING
External Voltage.
External supplied devices connected to relay 1 or 2 or to the
alarm relay can cause electrical shocks
Make sure that the devices connected to the following con-
tacts are disconnected from the power before resuming installation.
– relay 1
– relay 2
– alarm relay
WARNING
To prevent from electrical shock, do not connect the instrument
to the power unless the ground wire (PE) is connected.
Do not connect unless specifically instructed to do so.
WARNING
The mains of the AMI Transmitter must be secured by a main
switch and appropriate fuse or circuit breaker.

CAUTION
Risk of damage of the relays in the AMI Transmitter due to
heavy inductive load.
Heavy inductive or directly controlled loads (solenoid valves,
dosing pumps) may destroy the relay contacts.
To switch inductive loads > 0.1 A use an AMI relay box avail-
able as an option or suitable external power relays.
Inductive load Small inductive loads (max 0.1A) as for example the coil of a power
Resistive load Resistive loads (max. 1A) and control signals for PLC, impulse
Actuators Actuators, like motor valves, are using both relays: One relay con-
relay can be switched directly. To avoid noise voltage in the
AMI Transmitter it is mandatory to connect a snubber circuit in parallel to the load.
A snubber circuit is not necessary if an AMI relaybox is used.

2 relay contacts available, only one motor valve can be controlled.
