Abstract
A method for treating a wastewater process fluid includes: distributing air into a vessel having wastewater process fluid with an external air supply through an array of air diffusers; monitoring a state of the wastewater process fluid with an oxygen reduction potential (ORP) probe and a controller in operable communication with the ORP probe; and controlling a rate of the air supply to the wastewater process fluid by cycling of an air blower on and off. The time periods for operating the air blower are based on ORP readings. A biological selector system is also included.

A method for treating a wastewater process fluid comprising:
- distributing air into a vessel comprising wastewater process fluid with an external air supply through an array of air diffusers;
- monitoring a state of the wastewater process fluid with an oxygen reduction potential (ORP) probe and a controller in operable communication with the ORP probe;
- and
- controlling a rate of the air supply to the wastewater process fluid by cycling of an air blower on and off,
- wherein time periods for operating the air blower are based on ORP readings.
A biological selector system comprising:
- a vessel comprising wastewater process fluid;
- an array of air diffusers positioned within the wastewater process fluid;
- an oxygen reduction potential (ORP) probe positioned within the wastewater process fluid;
- a controller in operable communication with the ORP probe;
- and
- one or more computer-readable storage mediums in operable communication with the controller and containing programming instructions that cause the controller to monitor a state of the wastewater process fluid, and control a rate of the air supply to the wastewater process fluid by cycling of an air blower on and off.
