3. Product description
Fig. 1 System without cover and without peripheral devices; OCD-162-5 (left), OCD-162-30 (middle), OCD-162-60 (right)
The system produces and doses ClO
2
for the disinfection of
drinking water, process water, cooling water and wastewater.
The system has a plastic frame, where the internal components
are mounted. The frame is prepared for wall mounting or floor
mounting, and has a plastic cover.
The chemicals are supplied from two chemical containers, which
are located in two collecting trays directly under the system
(OCD-162-5, -10) or in a separate tray for each container next to
the system (OCD-162-30, -60).
Each container has a suction lance, which is permanently
connected to the corresponding dosing pump. The cable of each
suction lance sends low-level and empty signals to the control
unit.
The system is connected to two water lines:
• The drinking water line for supplying dilution water.
• The main water line to be disinfected, into which the final ClO
2
solution is dosed.
3.1 Applications
The system can be used for three different types of applications:
Disinfection of drinking water lines
• The flow rate of the water can fluctuate greatly (peak times
when water is used for bathing and cooking).
• The type and level of contamination in the water (disturbance
variables) can vary widely.
•Examples:
– Hotels, multi-storey buildings
– schools, hospitals, nursing homes
– showers in sports facilities
– food and beverage plants
– waterworks.
Disinfection of industrial systems
• Dosing is controlled proportionally to the flow.
• Dosing is controlled by comparing setpoint and actual value.
• The water quantity in industrial systems is relatively constant.
• The type and level of contamination in the water (disturbance
variables) are generally measured.
•Examples:
– Bottle cleaning plants in breweries
– industrial process water or wastewater systems
– cooling water systems.
Shock disinfection
This application requires an external batch tank where the ClO
2
solution is stored temporarily.
• Applications requiring large quantities of disinfectant in a short
time.
• Example: cleaning of whirlpool baths
3.2 Accessories
For the dilution water line
• Isolating valve
• Dilution water extraction device
• Tapping sleeve for dilution water extraction (if necessary with
double nipple and connection piece for a hose)
• Hose with connection to solenoid valve
For the main water line
•Water meter
• Tapping sleeve for the injection unit
• Protective pipe for the dosing line, installed from the dosing
pump to the injection unit
• Photometer: measures the ClO
2
concentration after dosing
• Sample-water filter (in case of insufficient water quality)
External batch tank
The production of ClO
2
continues, until the external batch tank is
full. If the maximum filling level of the external batch tank is
attained, the dosing pump stops.
If the minimum filling level of the external batch tank is attained,
the ClO
2
dosing pump starts running.
Bypass mixing module
The bypass mixing module improves mixing and reduces the risk
of corrosion in case of fluctuations in the main water flow.
