Membranes Membrane separation involves the use of thin barriers (membranes) between miscible fluids for separating a mixture. A suitable driving force across the membrane, for example concentration or pressure differential, leads to preferential transport of one or more feed components. Components can be selectively separated over a wide range of particle sizes. This can allow processors to simultaneously concentrate, fractionate, and purify their products. In addition, large volumes can be treated with remarkable energy efficiency. Synder Filtration membranes feature an asymmetric pore structure. Tighter surface pores control rejection characteristics, while larger pores beneath the surface promote greater throughput. Reverse Osmosis, Nanofiltration, and Ultrafiltration Membranes are characterized by their Molecular Weight Cut Off (MWCO), measured in Daltons, while Microfiltration membrane pore sizes are measured in microns. Synder offers two basic UF membrane chemistries: Polyethersulfone (PES) and Polyvinylidene Fluoride (PVDF), and one NF membrane chemistry. Cross Flow Technology ![]() Synder’s UF and MF membranes are also available in the special PHT series. The PHT series is capable of handling higher temperatures and pH during CIP and operation.
