TexAire

The TexAire Wastewater Treatment System is an economical alternative for use in treating domestic wastewater generated by normal household activities. The system consists of a single tank extended aeration activated sludge system which is capable of producing an effluent which meets applicable state discharge standard. This system has been successfully tested in accordance with the NSF/ANSI Standard 40.

The aeration process provides dissolved oxygen, mixing of the wastewater, and enough time for organisms or bacteria to break down the organic solids.

The TexAire aerates the wastewater in the aeration chamber following the pretreatment chamber. In the aeration chamber the wastewater is brown in color. This is caused by the return of sludge from the clarifier. As the water leaves the aeration chamber it enters a quiet zone where no mixing occurs. The quiet zone is referred to as the clarifier. In the clarifier the solids separate from the liquid and settle to the bottom: this matter is called sludge.

The sludge contains dissolved oxygen and this oxygen activates the bacteria it contains. This “activated sludge” is returned to the aeration chamber to be remixed. The sludge mixes with the incoming wastewater and this mixture of returned sludge and wastewater is referred to as mixed liquor.

This mixed liquor flows back to the clarifier; solids separate and return to the aeration chamber and so on and so forth.
