SEMASTTM Ultrafiltration Membrane

NYMOI Ultrafiltration Membranes are made of high-grade materials for long service life, with reinforced structure for excellent fiber strength, low filtration resistance, high flux and high separation precision via uniform pore structure. The modules have large contaminant capacity, easy cleaning and wide applications in surface/drinking/purified water treatment, sand filter backwash water reuse and wastewater treatment.

NYMOI External Pressure Hollow Fiber MBR Membrane

NYMOI external pressure hollow fiber MBR membranes adopt a high-strength fiber structure with excellent tensile and peel resistance for an extended service life. Equipped with a precision automatic potting process, the membrane fibers feature uniform spacing to effectively prevent sludge deposition. The membrane layer has a consistent uniform pore size, ensuring stable and high-quality produced water. Boasting high porosity and high flux performance, the membranes significantly reduce the operational and investment costs of the system. Treated with proprietary hydrophilic modification technology, they deliver strong anti-fouling capacity and stable flux operation. With convenient operation and maintenance as well as an extended cleaning cycle, NYMOI MBR membranes offer a wide application range and are suitable for various municipal and industrial wastewater treatment scenarios.
