Community Discovers Membrane Based Treatment Solutions

Aug. 25, 2009 - PRLog -- That’s because the new
1,000 acre planned residential community features a state of the art Bord na
Móna PuraM® Membrane Bioreactor wastewater treatment system that
makes maximum use of every drop of water.Bord na Móna was awarded the $1-million contract by Tennessee-based
Adenus Technologies in October 2007. The installation was completed in April
2008. The plant was designed to treat a Phase One flow of 250,000 GPD and
to achieve a final effluent quality of 10 mg/l BOD : 20 mg/l TSS : 10 mg/l TN.
What’s more, the design allows the final effluent to be used as a supply for
irrigation water on the development’s Greg Norman designed golf course.
The wastewater treatment system installed at this high profile mixed use
development incorporates the Bord na Móna enhanced air scour flat plate
cassette design, that reduces complexity, and operational input, a significant
benefit for decentralized treatment works. The PuraM system treats wastewater
to reuse standards and can be used for irrigation of the golf course. The
design allows for phasing that can expand the capacity of the works to meet
the future needs of this dynamic new community.
The PuraM wastewater plant is comprised of two treatment streams each
designed to handle up to 125,000 GPD. Each stream has an anoxic/equalization
tank and PuraM Membrane Bioreactor (MBR) tank. The system includes
18 flat plate PuraM membrane cassettes. Consideration was made in the
design to allow for complete ease of upgrading the system in future phases for
flows up to 1,000,000 GPD. The anoxic/equalization tanks were designed to
permit future conversion into PuraM MBR tanks.
While the Laurel Cove development marks the first U.S. installation of a
PuraM treatment system, similar PuraM systems are already in place in
Europe, where Bord na Móna’s parent company is headquartered. PuraM is a
pre-engineered wastewater solution that achieves high quality effluent within
a greatly reduced overall footprint. The PuraM MBR is engineered specifically
for the decentralized municipal, community and commercial wastewater
treatment market with an emphasis on reliability, reduced operational input,
ease of maintenance and less complexity than comparable systems.
PuraM is based on flat plate ultra-filtration membrane technology assembled
into stainless steel membrane cassettes. The cassette consists of a unique
integral dedicated air diffuser assembly that eliminates the need for backpulsing
or frequent chemical cleaning. The system does not require permeate
pumps or any site installed chemical dosing system while achieving a typical
time between recovery cleans of approximately 12 months, significantly better
than comparable systems.
