About this Project
CRS was contracted by Xstrata to design and deliver a potable water treatment plant to the Rolleston Coal Mine. A system comprising of oxidation, coagulation, clarification, automatic screen filtration, ultrafiltration, carbon filtration, raw, potable and fire water storage tanks, fire and potable pressure boosting pumps were used. Chemical dosing and compressed air auxiliary systems were also provided.
The plant utilises online monitoring of feed and treated turbidity, treated free chlorine and pH with automated chlorine dosing to maintain free chlorine levels. Coagulant dosing is automatically adjusted via SCD monitoring.
The plant is fully automated via an Allen Bradley Compact logix PLC and 12” touch screen located in the local control panel. The control system is configured to provide alarm notifications to the plant operators via SMS.
