Waste Water Treatment with Ozone

The performance of aeration equipment is critical to the successful operation of an activated sludge process. Often, in building a new plant, the performance of such equipment must be tested against the manufacturers specification in terms of power used for the quantity of oxygen transferred to the water.

Standard clean water Oxygen Transfer Efficiency (OTE) tests using nitrogen to purge oxygen out of the water, so reducing the Dissolved Oxygen (DO) concentration to zero, allow multiple tests to be carried out on new aeration equipment in a short time, giving data based on consistent methodology using a zero DO baseline.
