Haskell expanded and renovated a North Carolina wastewater treatment plant.

In an effort to match the growing demand for plasma-derived medicines and adhere to changing permit limits, this client needed to expand its wastewater treatment plant. With a reputation for delivering solutions to the Water sector that fit each community’s unique needs, Haskell was chosen to meet increased flow requirements and newly imposed municipal cleanliness requirements. 

The nuances of wastewater treatment plants require trained and tested expertise.

Modifications of the existing structure included the addition of a strainer in the headworks building, the replacement of all media in existing moving bed biofilm reactor (MBBR) blowers, and the enforcement of supporting piping and structures. MBBR aeration is known for its efficiency, space conservation and straightforward process. Its media is essential for providing a hospitable environment for microorganisms to grow. The biofilm then decomposes tank waste.

The improvements assure a consistent flow and discharge that meet municipal requirements.

New plant fabrication occurred in phases, the first including the creation of a new 1.5-million-gallon-per-day (MGD) aerated equalization tank. This tank ensures that wastewater flows at a consistent and balanced rate before further treatment, which is crucial for optimizing the efficiency and effectiveness of treatment processes. The new construction also installed an approximately 1.8-million-gallon precast concrete tank, supporting equipment building and sludge tanks. The precast concrete tanks include three trains, which facilitate the treatment process by isolating it, and each train includes an aerobic, anoxic and membrane portion of the tank. Following the tank, the process waste flows through the building and is safely discharged into the municipal wastewater system within the new limits.
