RO reverse osmosis water machine: pure water can completely remove harmful substances in the water, the water is pure water after purification. It is not enough water pressure to work under pressure, so it needs a booster pump, need the help of electricity and pressure. Its biggest drawback is that more wastewater, generally filter out about 50% of the waste water. Its high purification costs, less water production, can only be used to solve the problem of drinking water. Activated carbon filter: activated carbon strong adsorption force can heterochromatic and odor removal, but can not eliminate bacteria and other harmful substances in water, pure water filter for activated carbon and sediment, rust removal is relatively poor a. Ultrafiltration: ultrafiltration water purifier can effectively remove sediment, suspended solids, rust, bacteria, colloids and some organic molecules and other household water purification equipment prices, can effectively keep some of our useful minerals, trace elements Wait. Its advantage is that the filter long life, large volume of water, no power-pressurized, household water purification equipment that makes good, but compared to other purification devices, a lower cost and is very suitable for the purification of domestic water. White household water purifier ① polymer film forming method to be selected are compatible. For example, household water purification equipment, submerged ultrafiltration membrane casting preparation, the polymer must be dissolved in a solvent appropriate and safe. Combined with a film-forming polymer and methods shall be selected to obtain the performance and quality can be repeatedly reproduced ultrafiltration membrane. ② polymer shall have to meet specific application object properties. For example, household water purification equipment quality rankings, cellulosic polymer, its hydrophilic meet the requirements needed for the application of biotechnology low protein contamination, but it can not afford alkali cleaning agent; polyether sulfone having excellent alkali resistance, Suitable NaOH required cleaning applications, but it is strongly affected by protein contamination and less resistant to strong solvents and chlorine. ③ need commercially available polymer, a guaranteed supply, quality and affordable prices. Yue Han Technology (Figure), household water purification equipment quality rankings, household water purification equipment provided by the Henan Science and Technology Co., Ltd. Han Yue. Henan Yue Han Technology Co., Ltd. (www.hnlyjd.com/) is a professional "Electronic products, computer hardware, office supplies, water treatment equipment, communications equipment, refrigeration set up" company.
