Ocean City Wastewater Treatment Plant Biosolids Treatment Improvements. Ocean City, Maryland.
WRA conducted a one-year study for the Town of Ocean City, Maryland to evaluate the feasibility and provide recommendations for the addition of a sludge pasteurization process. The Town was faced with difficulties in disposing of the currently produced Class B sludge and was in need of flexibility and reliability for future disposal. WRA conducted evaluations of three sludge pasteurization processes, facilitating Class A sludge production. The Envessel Pasteurization™ process was recommended and WRA prepared designs and provided construction administration services for the new Class A Biosolids Treatment Facility. The new facility eliminated the previous operating problems and produces a beneficial Class A biosolids product, while significantly reducing operating costs.
WRA provided engineering services during construction and on-site resident project representation for the entire construction duration.
Biosolids and Residuals Handling
WRA prepared process mechanical designs to integrate the selected Envessel Pasteurization™ process equipment into the design. Other designs included rotary press dewatering equipment, thickened sludge holding tanks, and sludge pumping and conveyance systems.
A new building was designed to house all new process equipment. The building featured a truck bay drive through to facilitate loading of the Class A Biosolids.
The project included design of the concrete structure for the Biosolids Building, including augered pile supported foundations. Structural design included steel, concrete masonry, and cast-in-place concrete.
WRA designed all new underground utilities including utility relocations. A separate site preparation contract was prepared to facilitate the completion of the project.
A subsurface investigation was performed to determine on-site soil conditions and to provide foundation recommendations.
