Background
The Back River Wastewater Treatment Plant (BRWWTP) is a large WWTP situated on the west shore of the Back River, Maryland, which is a tributary of the Chesapeake Bay.
Originally opened in 1911, it is today operated by the City of Baltimore and plays a crucial role in treating wastewater for the region, serving approximately 1.3 million residents in a 140 square mile area of Baltimore City and County.
The plant occupies a 466-acre site and has a 35-foot elevation difference from influent to outfall, allowing wastewater to flow through the plant entirely by gravity.
Challenge
As part of the expansion and upgrade, the City of Baltimore approved the construction of a new Non-Potable Water (NPW) reuse project that treats 1000 gpm (227 m³/h) @ 50 micron.
The treated water will be used for the cooling process of the blowers serving the sludge pond. The particular blower specified for the project demands water that is free from particles larger than 50 microns.
Balancing this high flow requirement, stringent filtration standards, and the spatial limitations within the plant posed a significant challenge for maintaining efficient and uninterrupted operation.
Solution
Amiad provided a fully integrated solution including:
• 2 x Amiad EBS 10000 self-cleaning screen filters with custom-designed and fabricated face piping
• Valves
• Skid
• Control panel
The EBS Series offers unique performance thanks to its large filtration area, able to sustain high flow rates in presence of fine filtration requirements, down to 10 micron.
Amiad’s electrical-drive suction-scanning cleaning technology allows constant, dependable flow, and very effective cleaning cycles even at fine filtration degrees.
Results
The integrated solution was able to meet the requirement set by the project’s lead contractor, while keeping the footprint to a minimum.
The two Amiad EBS systems have been in operation since 2022, guaranteeing continuous operation with flow rates ranging between 700-1000 gpm (159-227 m³/h).
