Cross flow filtration – a filtration process in which feed water flows tangentially across a membrane surface – is widely utilized in wastewater filtration. The turbulence created across the membrane surface provides optimal flux performance and prolongs filter functionally.
Cross filtration works by introducing feed water under pressure across the membrane surface, instead of directly onto the filter. During filtration, any material smaller than the cross flow membrane pore passes through the membrane, while larger suspended particulates remain in the retentate stream.
