Detailed Product Description: | Ultrafiltration principle Ultrafiltration, also known as ultra-filtration, for the retention of colloidal size particles, water and low molecular weight solute is allowed through the membrane. The mechanism of ultrafiltration by the membrane surface mechanical screening membrane pore blocking and membrane surface and the adsorption of film hole effect, sieving. Ultrafiltration principle is also a membrane separation process principle, ultrafiltration using a pressure of active membrane, the retention of colloidal particles and a relatively high molecular weight substances under the action of the external driving force (pressure), and water and small solute particles through over the membrane separation process. Through the membrane surface of the porous filtering the MWCO 3x10000-1x10000 material. Of treated water by means of external pressure to the flow rate through the membrane surface, the water molecules and the molecular weight of less than 300-500 of the solute through the membrane, while larger than the membrane pore particles, macromolecules such as sieving effect interception, so that the water to be purified. That is, when the water by ultrafiltration membrane can remove the water contains most of the colloidal silica, while the removal of a large number of organic. Ultrafiltration is a pressure driven membrane separation technologies. Separation of macromolecules and small molecules for the purpose of the membrane pore size in the 20-1000A °. The hollow fiber ultrafilter (membrane) has a filling unit containers, high density, small footprint advantages. Reverse osmosis principle Material through selective film to become a semi-permeable membrane. Generally only through the solvent and not by the solute film as the ideal semi-permeable membrane. The same volume of dilute solution and concentrated liquid were placed in a container on both sides of the middle semi-permeable membrane barrier, the solvent in the dilute solution through the semipermeable membrane natural flow to the concentrated solution side, the concentrated solution side of the liquid surface will be higher than the surface of the dilute solution to a certain height, the formation of a pressure difference to reach osmotic equilibrium state, such a pressure difference is the osmotic pressure. The size of the osmotic pressure of concentrated liquid type, concentration and temperature and the nature of the semipermeable membrane has nothing to do. Exert a pressure greater than osmotic pressure in the concentrated solution side, the solvent in the concentrated solution to dilute solution flow, the direction of flow of such solvents, contrary to the direction of the original penetration, a process known as reverse osmosis Hollow ultrafiltration membrane The hollow fiber membrane is a of the ultrafiltration membrane. It is the most mature and advanced ultrafiltration technology. The hollow fiber diameter :0.5-2 .0 mm, internal diameter :0.3-1 .4 mm, covered with microporous hollow fiber wall aperture to intercept a molecular weight of the substance expression, molecular weight cutoff up to several thousand to hundreds of thousands. The flow of raw water pressure in the lateral or lumen of the hollow fiber, respectively, constitute the external pressure and internal pressure. Ultrafiltration is a dynamic filtration process are retained material with concentrated small to exclude from clogging the membrane surface, can be long-term continuous operation. The ultrafiltration membrane is one of the earliest development of polymer membranes. The ultrafiltration technology is a widely used in water purification, solution separation, concentration, and extract useful substances from waste water, waste water purification and reuse of high-tech in the field of. Is characterized by the simple process of using, without heating, energy conservation, low voltage operation, small footprint devices. |
