COLIFAST INSTRUMENTS CONTRIBUTE TO MONITOR RAW WATER QUALITY.
Both Colifast CALM and ALARM are suitable for various raw water application:
COLIFAST ALARM
MONITORS DRINKING WATER DISINFECTON PROCESS
Colifast ALARM is installed at the membrane filter rig at Jevnaker's drinking water treatment plant (DWTP). The instrument collects a 100 mL sample every 24 hours, testing for total coliforms. Results are sent directly to the DWTP control room via PLC
RAW WATER MONITORING WITH COLIFAST CALM
Three CALM instruments continuously monitor Gothenburg's raw water. The analyses are completed in 12 hours and results are directly transferred to the control room at the treatment plant. Water treatment is optimized based on bacteria levels reported by the instruments.
GROUND WATER MONITORING WITH COLIFAST ALARM
GIVAS, an inter-municipal water utility in eastern Norway, typically has high-quality groundwater. However, during water floods, the water can infiltrate the aquifer. To ensure good water quality, chlorination begins when the river reaches a certain level and stops based on negative results from the Colifast ALARM system. This has resulted in shorter, more precise chlorination, enhancing water quality for consumers.
