INJECTION SYSTEM FOR WASTEWATER TREATMENT
20200095143 · 2020-03-26 ·

A system and method for monitoring and altering the conditions of a sewage system comprising a wet well connected to a sewer. The wet well is also configured to provide sewage to a secondary system, where the sewage is fed into an oxygen contact chamber. That chamber is fed oxygen which is dissolved into the sewage such that the sewage in the contact chamber has elevated oxygen content. That oxygenated sewage is then fed into the sewage system in order to raise oxygen levels and control anaerobic activity. Sensors and valves of the system are controlled by a central controller which provides for improved functionality, energy savings, and automated function.
