Fouling is the most common fault affecting the service life of RO membrane, mainly divided into particulate fouling, colloidal biological fouling and chemical scaling. Scaling can be controlled by adding scale inhibitors, while particulate and biological pollution can only be solved by optimizing the pretreatment system with UF membrane. Even if equipped with precision high-flow …

The high-flow filter cartridge installed before RO membrane is the last critical physical protection barrier of the reverse osmosis system. Conventional small filter cartridges require a large number of parallel installation, occupying space and increasing labor replacement costs. Our pleated large-flow security filter cartridge has high dirt holding capacity and low pressure drop, which can …

PVDF hollow fiber UF membrane is the preferred filtration material for harsh wastewater working conditions, relying on excellent hydrophilicity, chemical corrosion resistance and tensile strength. Compared with PES membrane, PVDF UF membrane can withstand repeated sodium hypochlorite high-concentration cleaning without fiber cracking. For oilfield produced water carrying crude oil emulsions and municipal tertiary wastewater with …

Most industrial water treatment failures of RO membrane are caused by incomplete pretreatment without UF membrane. Raw industrial water contains massive clay colloids, algae and biological slime, which traditional multi-media filters and single security filters cannot fully intercept. Tiny colloids will form dense pollution layers on the surface of RO membrane, resulting in rising operating …
