OVER VIEW OF ULTRAFILTRATION CERAMIC MEMBRANE ELEMENT
Ultrafiltration ceramic membrane is a variety of membrane filtration in which forces, such as pressure or concentration gradients, cause separation through the semi-permeable membrane. High molecular weight suspended solids and solutes remain in the so-called retentate while water and low molecular weight solutes pass through the membrane in the permeate (filtrate). The pore size of the ultrafiltration ceramic membrane is in the range of 0.01μm ~ 0.05μm, suitable for the separation, concentration, and purification of macromolecules and small molecules.
A versatile and economical solution for clarification, concentration, and purification of liquids, ultrafiltration ceramic membrane could remove emulsified oils, metal hydroxides, colloids, bacteria and viruses, emulsions, dispersed material, suspended solids, and other large molecular weight materials from water and other solutions. Ultrafiltration ceramic membrane also serves in critical parts of the production processes of fruit juice, milk and whey, electrocoat paints, pharmaceuticals, poly-vinyl alcohol, and indigo dye. It is key to surface water treatment for potable uses and wastewater treatment for reuse. Ultrafiltration ceramic membrane is used to recycle flow or add value to later products and more. In many cases, ultrafiltration ceramic membrane is used for prefiltration in reverse-osmosis plants to protect the reverse-osmosis process. Ultrafiltration ceramic membrane is an effective means of reducing the silt density index of water and removing particulates that can foul reverse osmosis membranes.
