UF is a separation process using membranes with pore sizes in the range of 0.01 to 0.1 micron. Typically, UF membranes will remove high molecular-weight substances, colloidal materials, and organic and inorganic polymeric molecules.
This UF Membrane NM-UF-90 is special designed for industrial small project like less than 5000Ltr/Hour.
Hinada has PVDF material and PVC material hollow fibers, the UF Membrane UF-90 design capacity around 500 Liters / Hour for surface water filtration.
