Safe and Controlled Disinfection of Drinking Water
Koerich water works near Luxembourg City is one of the Grand Duchy’s most important water works. A high-level
tank with a volume of 161,460 ft³ (15,000 m³) plus an additional 70,620 ft³ (2,000 m³) was newly constructed for storage.
ProMinent’s task was to design and construct a generator which would ensure safe and reliable disinfection of drinking water, round the clock, 365 days a year.
Challenge
- Efficient disinfection of the drinking water without impairing taste or odor, within the
framework of legal requirements - Safe, continuous, automatic operation with the lowest possible expenditure on operation and maintenance
- Safeguarding the quality of the drinking water all the way to the consumer’s tap
Solution
- Metering and supply concept with chemical storage vessels, chlorine dioxide generating plant, collection module for intermediate storage of stock solution and
volume-proportional metering into various pipelines using Sigma pumps - Metering points with diaphragm valves and complete monitoring of the entire system
by PLC maintain the highest levels of safety - In addition, chlorine dioxide, redox and pH are measured and monitored
Customer benefits
- Safe disinfection of the water and permanent neutral-tasting and odorless water quality through the residual effect of chlorine dioxide
- Automated operation of the generator reduces costs and ensures 24-hour operation, 365 days a year
- Operating parameters can be reported to the control room
What the Customer Said
“This technically-advanced disinfection plant was professionally designed and constructed. People living in the
region will be able to enjoy their drinking water with a pleasant, neutral taste and with no fear of pathogens.”
Tom Levy, technical director, Koerich waterworks, Luxembourg
