4 inch Ultra-filtration Membrane Module for Pure Water Purification with PVDF material
Ultra-filtration is an advanced technology to separate, purify and concentrate substance . It presents hollow capillary tube shape or hollow fiber shape, micro-pore covers tube wall densely. Feed liquid is flowing in or out the membrane under the influence of pressure, dissolvent or small molecule can permeate membrane and become pure liquid by collection, while large molecule (such as protein, each kind of enzyme, nucleic acid, polysaccharide and so on) ,colloid particle (such as emulsion, micro-ion) and bacterium are cut off by the membrane and are taken off by the circulating liquid flow to become concentrating liquid. waters.
UF provide:
* High and consistent product quality measured by turbidity (NTU) or silt density index (SDI).
* Tolerance to feedwater quality upsets.
* No use of pretreatment chemicals (polymer, coagulant, pH adjustment) and associated costs for sludge disposal.
* Small footprint and less weight than media filters.
