3.2 Dose Curves
Flow rate, UVT, and required UV dose conditions dictate which sy s tem is appropr i ate
for a given location.
Dose values such as those in the following graphs are calculated based on set-points.
Set-point conditions are determined by third party verified bioassay testing completed in
compliance with the 2006 UV Disinfection Guidance Manual (UVDGM).
Each of the PRO systems has a unique flow restrictor to limit flow rates to 10, 20, and
30 GPM for the PRO10, PRO20, and PRO30 systems respectively. These restrictors
are found in the inlet port of the chamber and physically inhibit flow rates from
exceeding maximum design flow.

4. Lamp operation indicator
5. Controller operation indicator
6. Solenoid valve operation indicator
7. Fan operation indicator
8. Sensor reading indicator

Firmware in the controllers monitors flow rate and sensor input for set point conditions.
Controllers will enter audible and visual alarm if the sensor input is too low given the
measured flow rate. Set points depend on the Adjustable Alarm Set Points (sec. 3.7.3).

3.4 UV Lamp
3.4.1 Mercury Discharge Lamp Spectral Output
The lamp produces germicidal ultraviolet light (UV-C) at a wavelength of 253.7 nm. The
absence of a peak at 185 nm is significant because it means no harmful ozone will be
produced. VIQUA’s PRO system amalgam lamps have a mercury content of less than
15 mg (IMERC registered).

Spectral Irradiance (%)

155 205 255 305 355 405
Wavelength, λ (nm)
VIQUA’s amalgam lamps use a mercury amalgam matrix as opposed to mercury in its
pure liquid form. Therefore, the mercury is contained as a secure, solid segment.
Additionally, this segment is trapped in a compartment at the bottom of the lamp.
In the case of a broken lamp, this compartment
would contain the mercury. Even if this
compartment also broke open, the quartz sleeve
prevents the mercury from coming in contact
with water flowing through the chamber.
Features
• All electrical connections made at one end of the lamp.
• Lamp base features a di aboli c barr i er w hich prevents arcing between pins.

3.4.4 Quartz Sleeve
The UV lamp is enclosed by a quartz sleeve made of GE Type 214 or equivalent clear
fused silica quartz.
Mineral deposits will form on the quartz, which inhibit the amount of light that can reach
the water. The sleeve must be manu al ly cleaned on a regular basis using a mineral acid
such as a calcium, lime, and rust remover.
3.5 UV Sensor
Many factors influence a system’s level of UV disinfection. Some of these factors
include water quality (primarily UVT), lamp output, and quartz sleeve fouling. Rather
than base set-points on any one of these factors, alarm set-points are based on the
quantity of light that actually reaches the sensor. In this way, the UV sensor detects
when the water is no longer being purified properly as a result of change in any
influential factor. VIQUA’s UV sensors reliably detect low UV output and identify the
need for maintenance.

3.6 Flow meter
The flow meter measures the flow rate of water passing through the UV systems. The
flow meter utilizes a paddle wheel and a flow detect arm to ensure reliable
measurements.
3.7 Product Features and Benefits
3.7.1 Real-Time UV Dose Monitoring
VIQUA’s PRO systems come equipped with real-time UV dose monitoring which utilizes
data from both the flow meter and the UV sensor.
Benefits
• More accurate assessment of true operating conditions.
• More time between maintenance.
• Lower probability of false alarms.

3.7.2 LightWise™ Technology
VIQUA’s new LightWise™ technology allows the system’s electronic controller to
automatically reduce lamp power during periods of no water flow. The dimmi ng
capability ultimately reduces the rate of sleeve fouling.
Benefits
• Lower maintenance; up to 60% less maintenance.
• Lower energy consumption; estimated savings of 30%.
• Lower operating temperature; maintained below 40°C in typical no flow conditi ons.
• Increased electrical efficiency minimizes carbon footprint.

3.7.3 Adjustable Alarm Set Points
The PRO10, PRO20, and PRO30 systems are all capable of programmable low UV
dose alarm set points of 40, 80, or 120 mJ /cm2. After detecting a low UV dose, a visual
and audible alarm will sound within the allowable response time (the time it takes for
three void volumes to pass through the system, plus 3 seconds), as per NSF Standard
55 Class A protocol.
System
Benefits
• Allows for system compliance with regional regulations.
• Ability to tailor low UV alarm set point to custom applica ti on.
• Reliable system response time to alarm situations.
• Visual and audible alarm activation.
3.8 Signals and Remote Capabilities
3.8.1 COMMcenter™
The COMMcenter™ provides live monitoring and records past
performance. When a Mini-SD card is inserted into the system,
information is recorded every minute. A 512 MB Mini-SD card should
store 18 years-worth of information. Without the Mini-SD, the
COMMcenter™ will store the last 40 alarms that have occurred in
memory.
Features
• Displays real-time dose measurements.
• Notifies alarm situations and provides help screens to overcome the problem.
• Archives past performance, water quality changes, power failures, alarms, and lamp
age.
• RJ45 Ethernet cable connection between COMMcenter™ and controller.
• Equipped with a 2 GB Micro-SD card and Mini-SD adapter.
3.8.2 Dry Contacts
The dry contact can be used to signal a remote device in event
of the following major alarms:
