Waste Water Reclamation Plant Three | Secondary Treatment

Aeration

The most complex and interesting part of a wastewater treatment plant is the biological process. The water leaving the barscreen still contains solids and disease causing bacteria. In secondary treatment we culture bacteria and protozoa to consume the solids and destroy any dangerous viruses or bacteria. This stage of treatment is a carefully controlled artificial environment where microorganisms that live in nature can be used in a fast and efficient manner. We control the oxygen content, the mixing, the temperature, the contact time, and the microorganism population size.

All tanks in the new plant are covered for odor control and to improve efficiency in cold weather.
