Veolia RO Membranes | GK Series | GK4040F50

The GK Series ultrafiltration (UF) spiral wound membranes are characterized by a molecular weight cutoff (MWCO) of 3,500 on polyethylene glycol (PEG) and a smooth, fouling resistant membrane surface.

GK spiral wound membranes are used for surface water pretreatment, color, or total organic carbon (TOC) reduction, and chemical purification.
