Ultrafiltration (UF) membranes are a type of membrane filtration in which forces like pressure or concentration gradients lead to a separation through a semipermeable membrane. Suspended solids and solutes of high molecular weight are retained, while water and low molecular weight solutes pass through the membrane. This process is used in both industrial applications and in the treatment of wastewater. Fresco is represented more than three brands, i.e. Deerfos, GRAFil and QUA Membranes
