The Client

Town of Middletown, DE

The Problem

1.0 MGD wastewater treatment system needed for nitrification-denitrification for pretreatment of Rapid Infiltration Basisns (RIBs).

Technology Solution

The rapidly growing Town of Middletown, DE needed a new 1.0 MGD wastewater treatment system to achieve effluent limits of < 2 mg/L ammonia and < 10 mg/L Total Nitrogen (TN) prior to application to the rapid infiltration basins (RIBs).

In December of 2019 twelve Webitat modules were installed in the aerated tank and eight were installed in two subsequent anoxic channels. The total of 20 Webitat modules provided over 110,000 ft2 of BioWeb media necessary for nitrification-denitrification. Entex supplied blowers, pumps, controls, instrumentation and valves for the Webitat system.
