Clearwater Industries Autofloc polymer dosing system automates polymer dosing to ensure optimal water clarifier performance.  Monitoring the water’s clarity in the center well, and adjusting polymer dosing accordingly, our AutoFloc acts as an around the clock operator ensuring polymer efficiency and minimizing use.

Clearwater also manufactures dry feeders, pump skids, sumps, and pumps.  These systems are typically custom-designed to the specifications required by the application.

Automation of Coagulant and Flocculant Dosing

Typical Process: 

Many industries use clarifiers or thickeners to remove suspended solids from wastewater flow streams. Usually, producers add coagulants and flocculants to aid in the removal of suspended solids. These additives are mixed with the wastewater stream and directed to the center well of a clarifier or thickener.

When unadjusted for differences in suspended solids, flow rate, or reaction efficiencies, the plant may underdose, resulting in poor water quality or overdose contribution to excessive use. In extreme cases, overdosing can result in the mechanical failure of clarifier components.

Clearwater Industries Advantage:

A Clearwater Industries Autofloc System will automate the coagulant and flocculant dosing to optimize clarifier performance.

Clearwater Industries stainless steel AutoFloc probe held in an employees hand to show it's size.

To do this, we install our stainless steel Clearwater Industries Autofloc Centerwell Probe in the center well of the clarifier.  Infrared light absorption is detected in the flocculation zone and relayed to the Clearwater Industries Autofloc Messenger.

The messenger adjusts the associated dosing pumps via an analog 4-20 mA output signal to account for changes in light absorption seen in the center well.  A touch screen interface allows users to adjust the outputs sensitivity, air-sparging cleaning events, set alarm relays, monitor real-time readings, and review historical data.  The Autofloc Messenger can output (4) analog outputs and accept (4) probe inputs.

Operators can further automate the process with Clearwater Industries Autofloc Clarity Probe.  The probe, similar to the Centerwell Probe, uses a larger gap to detect the lower level of solids expected at the clean water overflow.  This probe will provide coagulant dosing automation and clean water overflow alarms.

Real-time coagulant and flocculant control results in reduced consumption rates and improved process reliability.  For more information on this application, or others, please contact Clearwater Industries at (414)365-1200 or sales@clearwaterind.com.
