3.0 SYSTEM OVERVIEW
3.1 4-Log Virus Reduction
The PRO24-186 system provides over 186 mJ/cm2UV dose for 4-log reduction of
viruses, including the Adenovirus. The system consists of two chambers in series
utilizing amalgam UV lamps, CoolTouchTM, and LightWiseTM technology. The
Adenovirus system is fully third-party validated to USEPA UV Disinfection Guidance
Manual (UVDGM) protocol for 4-log Adenovirus reduction.In addition to the virus
reduction, each of the chambers has been validated to provide 4-log reduction of
Cryptosporidium and Giardia.
Benefits
•Ultra-high output amalgam lamp technology allows for compact installation.
•Intense disinfection dose reduces or removes the need for chemical treatment.
•Real-time UV intensity and flow rate sensor activate visual and audible controller
alarm.
3.2 Pressure Drop
The pressure drop across the system is proportional to the flow through the system.

3.3 UV Dose Monitoring
3.3.1 Dose Curve
Dose values such as those in the following graph are calculated based on third-party
verified bioassay testing completed in compliance with the 2006 UVDGM.
There is no flow restrictor on the Adenovirus system. Therefore, the system can
physically exceed 24 GPM; however, at flow rates above 24 GPM the system will go
into alarm and the solenoid valve, if connected, will cut off the flow of water.

3.3.2 Dose Alarm Selection
VIQUA’s Adenovirus system comes equipped with real-time UV dose monitoring which
utilizes data from both the UV sensor (3.3.3) and the flow meter (3.3.5). The system will
go into alarm at different points depending on input from these components. There are
two dose settings to choose from: variable or stepped dose alarm. The system will
come factory set as variable but may be set to stepped depending on regional
regulations.

3.3.3 UV Sensor
Many factors influence a system’s level of UV disinfection, including water quality
(primarily UVT), lamp output, and quartz sleeve fouling. Rather than basing 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 flowing
furthest away from the lamp is no longer being disinfected properly due to any factor.
VIQUA’s UV sensors reliably detect low UV output and identify the need for
maintenance via a 4-20 mA output signal to the controller.
Features
•Factory assembled and calibrated.
•UV monitored by a silicon carbide photodiode for long term stability.

9
3.3.4 Sensor Response Curve
The sensor’s photodiode detects the emitted germicidal 253.7 nm wavelength.
3.3.5 Flow Meter
The Adenovirus system uses a single flow meter located on the primary unit to measure
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. The flow meter outputs
a 4-20 mA signal to the controller.

3.3.6 Controller Interface
Each controller is equipped with the following features:
1. Audible alarm
2. Audible alarm mute
3. Replacement lamp counter reset
4. Lamp operation indicator
5. Controller operation indicator
6. Solenoid valve operation indicator
7. Fan operation indicator
8. Sensor reading indicator
9. Flow meter operation 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 Dose Alarm Selection (sec. 3.3.2). The
controller’s alarm conditions act independently of the COMMcenterTM (sec. 3.3.7);
though the Adenovirus PRO24-186 should always be operated with the COMMcenterTM,
this means the UV disinfection dose is monitored even if the COMMcenterTM should fail.
To achieve 186 mJ/cm2 both systems must be on and working properly. Should one
controller lose communication with the other, or if the COMMcenterTM loses
communication with either controller, the system will go into visual and audible alarm.
Features
•Continuously monitors and controls the system.
•Communicates minor and major audible alarms when conditions fall outside the
USEPA UVDGM prescribed operating range.
•Auto-ranging (Operates with any input voltage between 100 and 240 V).
•Constant Current.
3.3.7 COMMcenter™
The COMMcenter™ provides live monitoring, records performance,
and allows for communication between the two controllers. It is
connected to the primary unit on the Adenovirus system. 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.
Features
•Displays real-time dose measurements for individual units and the combined dose.
•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.
3.4 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 amalgam lamps have a mercury content of less than 15 mg (IMERC
registered).
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.
Features
•All electrical connections made at one end of the lamp.
•Lamp base features a diabolic barrier which prevents arcing between pins.
3.4.2 Degradation Chart
Amalgam lamps have a useful life of approximately 18,000 hours. They can provide
adequate disinfection for up to two years and then require replacement.
3.4.3 Temperature Profile
VIQUA’s lamps use a mercury amalgam mix to control the vapour pressure and
produce a more stable output than conventional standard output lamps.

3.4.4 Quartz Sleeve
Each 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 manually cleaned on a regular basis
using a mineral acid such as a calcium, lime, and rust remover.
3.5 Product Features and Benefits
3.5.1 LightWise™ Technology
VIQUA’s new LightWise™ technology allows the system’s electronic controller to
automatically reduce lamp power during periods of no water flow. In order to maintain
dose levels above alarm setpoint values, the controller will dim to 62% power output.
The dimming 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 conditions.
•Increased electrical efficiency minimizes carbon footprint.
