AF-2 Automated Chemical Control

TSS Monitoring

The Advantage Feed (AF-2) system relies on spectroscopy rather than the human eye. A durable TSS sensor placed in the wastewater effluent stream sends critical information to the AF-2 Controller. The sensor is cleaned automatically to ensure accuracy.


Desired effluent TSS is programmed by management into the system by selecting a minimum and maximum range and entering the set points via the AF-2 color touch screen. Real time TSS value is constantly displayed.


The AF-2 is designed to control coagulant and polymer chemical feed pumps. AF-2 output wires are connected to chemical feed pumps and (4 – 20 mA) signals from the AF-2 ramp the pumps up or down to meet set point. The system calculates and adjusts the feed pumps every 57 seconds or when necessary.


Only the best quality components have been selected for the AF-2 to insure reliability. The system is on call 24/7 – 365. It never gets sick or takes a vacation.
