enhanced nutrient removal upgrade

The project included demolition of an existing aerobic digester and half of the existing drying beds to make room for a new packaged engine generator system and Dewatering Building. The Dewatering Building consisted of a screw press, two progressive cavity sludge feed pumps, grinder, two positive displacement blowers for the existing aerobic digester, and a new electrical room to facilitate the new electrical service and power/controls for the Dewatering Building. A new two-level Denitrification Filter Complex (DFC) was also constructed. The DFC consisted of a wet well, mud well, three filters, clear well, UV and effluent channels, sodium hydroxide tank and containment area, three filter influent pumps, two mud well pumps, three plant water pumps, two positive displacement backwash blowers, two backwash pumps, three sodium hydroxide pumps, tablet chlorination system, UV system, and clear well diffusers.
