Compass EOR (enhanced organics removal) is a coagulation control system which characterises NOM and automatically ensures the right amount of coagulant is being dosed to remove the organics in the raw water entering a water treatment works. Using the full UV-Vis spectral analysis on the raw water enables the Compass software to react to changes in water quality proactively, ensuring low filtered water turbidity, maximum organics removal and minimising chemical dosing. Compass EOR also utilises a UV 254 measurement on the common post clarified water as a feedback mechanism to the system to ensure organics are being removed and DBP formation potential is reduced.
The Compass EOR system consists of a fully submersible UV-Vis spectrophotometer (the s::can spectro::lyser) which is installed on the raw water and measures from 200-750nm every two minutes. This spectral data is fed into the concube controller and several individual wavelengths are output to the Compass EOR controller via Modbus. Additionally, the concube also takes in an analogue input from a raw water turbidity and post clarified UV254 monitors.
