microfiltration
Largest submerged microfiltration plant in the UK achieves reduced capital costs compared to traditional, pressurized systems by utilising small footprint of Memcor microfiltration technology
Farlington, in Portsmouth, has the newest and now largest submerged microfiltration plant in the UK, and achieved reduced capital costs compared to traditional, pressurized systems by utilising the small footprint of Memcor microfiltration technology Designed and built by Black and Veatch Contracting, the recently commissioned 84Mld microfiltration plant comprises six Memcor membrane filtration cells, each cell consisting of PVDF membrane modules

Water re-use award for Memcor .....in Honolulu?!
A high-tech Memcor treatment facility that recycles wastewater for manufacturing and irrigation use has won the WateReuse Association's 'Outstanding Contribution to Sustainable Water Use' award
For future demands requiring increased flows, a seventh filtration cell has also been installed - but without any significant impact on the overall cost of the project.
Created to provide a barrier against cryptosporidium, and ensure further safeguards to supplies to 200,000 people in Portsmouth, Havant and Hayling Island, water quality at Farlington benefits from daily automatic integrity testing to provide evidence of removal efficiency.
The Memcor system, comprising six CMF-S units, is designed to achieve a minimum net output of 80 MLD with an instantaneous input of up to 85 MLD, and an influent turbidity of less than 0.4 NTU.
The system is also designed to achieve a minimum net output of 70 MLD with an instantaneous input of up to 74.4 MLD with an influent turbidity of less than 1 NTU.
Each CMF-S unit incorporates 396 micro-filtration modules containing PVdF hollow fibre membranes with a pore size of 0.2 microns.
Feed water passes through the walls of the hollow fibres to the centre of the fibres producing a filtrate virtually free of suspended solids, which accumulates on the outer surface of the membranes.
