Facility Size: 50 homes and community amenities
The Boston-based developer of the Noquochoke Village affordable housing project had an uphill battle with proposing affordable housing in Westport, Massachusetts. Allen & Major Associates — working with the design engineer along with J&R Sales & Service (BioMicrobics’ Massachusetts distributor) and Wastewater Treatment Services (the installer) — began working to design a decentralized, community-based, aerated membrane bioreactor system in the summer of 2018, and the system was installed and started up in May of 2019.
“In evaluating system design alternatives and service vendors, we were pleased to coordinate with J&R Sales and Service, who brought a wealth of knowledge to the design team on how a BioMicrobics [BioBarrier MBR] system can meet the demands, be adjusted based on varying field conditions, and be reliably maintained,” says Phil Cordeiro of Allen & Major Associates.
Installed below the parking lot in locally sourced tanks, the BioBarrier HSMBR system also met water quality requirements for the reduction of chemical and microbiological contaminants and established the material, design, construction and performance requirements for other onsite residential and commercial applications. It consisted of a 10,000-gallon flow equalization tank; followed by a 20,000-gallon settling tank with BioMicrobics SaniTEE effluent screens; two three-compartment 8,000-gallon tanks with BioBarrier HSMBR 6.0-N each with two compartments creating anoxic zones; 3,500-gallon pump chamber; alkalinity feed system, installed but currently not needed, as the MicroC is available as a carbon source; and drip tubing for dispersal.
“We think the most interesting part of this project is that the local regulators were looking for “net zero” nitrogen at the property line and with the BioBarrier treatment train, we were able to achieve a 98% TN removal. The BioBarrier system was selected for this site to meet a local TN requirement of <5 mg/L TN. The system has consistently met this requirement,” says Cordeiro.
With more than 80,000 wastewater treatment systems installed in over 80 countries, we assist clients with providing more options and high-performance technology to meet and exceed regulatory compliance and end-goals for water quality, including water reuse opportunities.
