Automatic Coagulation Control

Pi’s CoagSense coagulation controller is an integrated controller that accepts multiple inputs from appropriate parameters including pH, flow, temperature, UV254, turbidity and streaming current. From these measured parameters, the CoagSense outputs a flow proportional coagulation control signal that can go to a site SCADA or direct to control a coagulant dosing pump. CoagSense Coagulation Controller Coagulation is affected by multiple variables associated with and individual to any one water treatment site. These include but are not limited to: • raw water pH, alkalinity, turbidity, organic loading, temperature • coagulant used • post coagulant pH, temperature • physical aspects including dosing point, mixing etc. These variables are typically different from site to site, water source to water source, and even day to day. Pi believes that one size does not fit all. One method of coagulation control cannot be trialled at one site and rolled out across many. Each system needs to be designed and specified for each water treatment plant and that is a service offered by Pi. Prior to changing existing coagulation control, it may be beneficial to install and monitor how well an existing coagulation controller is doing by installing a coagulation analyser.
