Membrane ultra-filtration unit ZeeWeed 700B

for water

ZW700B using SevenBore* fiber technology Veolia's ZW 700B inside-out ultrafiltration (UF) membranes use a blended polyethersulphone (PES), allowing the membrane to stay permanently hydrophilic and reduce the fouling tendency. When compared to granular filter media and cartridge filters, the ZeeWeed* 700B membrane produces superior water quality and is much more resilient to variable raw water quality. An inside-out SevenBore* membrane, available with Seabreeze or RMS, (Rackless Module System), technologies, ideal for low solids and seawater reverse osmosis (SWRO) pre-treatment applications. The ZeeWeed 700B is a pressurized hollow-fiber membrane employs a blended polyethersulphone (PES) allows the membrane to stay permanently hydrophilic and reduce the fouling tendency which is crucial to an efficiently run plant. The product features SevenBore* fiber technology. This innovative design incorporates seven bores within each fiber, producing a mechanical strength that is 10 times higher compared to single-bore fiber. The ZW 700B is a versatile product that can easily retrofit other ultrafiltration and microfiltration systems. This unique membrane contributes to a lower operational and lifecycle costs by reducing power, maintenance, chemical and replacement expenses compared to conventional, pressurized single-bore UF options.
