The Goulburn Mulwaree Council decided to conserve potable water by reusing treated effluent for agriculture irrigation. The project was contracted out to Ted Wilson & Sons, which used a pressured on-demand irrigation scheme designed to simplify the infrastructure and lower costs.
According to CST, its Berson InLine medium pressure lamp technology was used to treat the effluent, resulting in a high water discharge quality which eliminated the need for further civil works. Its technology has been fully integrated into the council’s PC/SCADA process control system.
UV light is known to kill microbes and is widely accepted as a way of disinfecting industrial wastewater from factories before its reuse or release into the environment. Medium pressure UV is polychromatic with a variety of wavelengths, preventing photo-reactivation of the microbes.
The council says it was already using effluent for irrigation before the system was installed, but the UV-treated effluent could be used for more purposes.
CST Wastewater Solutions provides a range of wastewater treatment services and technologies such as water and wastewater screening, grit removal, dewatering, and sludge dewatering.
