GE's new ZeeWeed 700B horizontal-designed, inside-out ultrafiltration (UF) membrane offers seawater pretreatment for injection and solids removal in offshore oil and gas applications.
Using SevenBore fiber technology, ZeeWeed 700B are blended polyethersulphone (PES) membranes, which allow 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 virtually unaffected by variable raw water quality. It extends the life of a sulfate removal unit by providing an improved pretreatment technology, decreased life cycle costs and reduced weight as well as footprint. In cases where GE ZeeWeed 700B UF membranes are used purely for solids removal, it also offers superior reservoir protection.
The GE ZeeWeed 700B membrane uses multibore fibers, which are stronger than single bore fibers and minimizes maintenance and repairs. It does not require air scouring and eliminates the need for blowers. GE's UF technology is energy efficient, operating at a lower transmembrane pressure with lower energy requirements.
GE's ZeeWeed technology is an advanced filtration technology that separates particles, bacteria and viruses from water or wastewater. Nearly 1,000 plants worldwide use this technology to produce superior quality water. Its unique ability to handle large volumes of water in a small footprint, combined with the highly efficient process with low energy and low chemical usage, makes it ideal for treating raw water sources like seawater and producing high-quality process water for the oil and gas industry.
