Coagulation Controller – CoagSense
Pi’s CoagSense coagulation controller is a comprehensive solution designed to optimize coagulation control by integrating multiple input parameters, including pH, flow, temperature, UV254, turbidity, and streaming current. Using these inputs, the CoagSense provides a flow-proportional coagulation control signal that can either be sent to the site SCADA system or directly control a coagulant dosing pump.
Customised Coagulation Control for Every Site
Coagulation is a complex process influenced by numerous variables that differ across water treatment sites. Key factors affecting coagulation include:
These variables can vary from site to site, water source to water source, and even day to day. Pi recognizes that "one size does not fit all." A coagulation control strategy trialed at one location may not work at another, and each system must be custom-designed to meet the specific needs of individual water treatment plants. Pi offers this bespoke design and specification service to ensure optimal coagulation control.
Assess Before Upgrading
Before modifying existing coagulation controls, Pi recommends installing and monitoring a coagulation analyser. This allows operators to evaluate the performance of their current control systems and identify areas for improvement, ensuring any updates are data-driven and effective.
Key Benefits
Applications
Historically, multi-parameter coagulation control systems have been PLC-based, overly complex, costly, and often criticized for lacking robustness and reliability. The CoagSense coagulation analyser from Pi offers a stand-alone, instrument-based solution that is fully configurable to handle site-specific and within-site variations.
Water treatment facilities have traditionally attempted to control coagulant dosing using a single parameter—such as pH, turbidity, streaming current, or UV254—with mixed results. Pi’s CoagSense coagulation analyser enables flexible control using one, multiple, or all of these parameters, ensuring greater accuracy and efficiency in coagulation control.
Options
The CoagSense coagulation controller is versatile and can be employed in various configurations:
The CoagSense system is adaptable, with options to meet diverse site requirements. Available features include:
With these options and configurations, the CoagSense coagulation analyser empowers water treatment professionals to achieve optimal process performance tailored to their specific needs.
