Tertiary Wastewater Filtration

Final effluent polishing for reuse, recycle or discharge to the environment

Tertiary treatment, also referred to as effluent polishing, is required to improve water quality in the wastewater treatment process before discharge to the environment. Most wastewater treatment plants use at least one tertiary filtration system to accomplish coagulation assisted filtration, absolute barrier filtration or nutrient, removal which includes biological denitrification and chemical phosphorus removal. As wastewater is purified to higher degrees by such treatment processes, the treated effluent can then be reused for irrigation, recreational use or water reuse.

Evoqua offers a wide range of tertiary filtration technologies that include disc filtration systems as well as gravity sand filtration systems
