How to increase the water volume in the operation of Guangdong secondary reverse osmosis pure water treatment equipment? Author: With economic development, various places a lot of large industrial, large-scale industrial production, large-scale reverse osmosis water treatment equipment is used in industrial production more of a water treatment equipment for industrial belt There are many conveniences and benefits. The reverse osmosis membrane used in the large-scale two-stage reverse osmosis pure water equipment has a very small pore size, and the osmotic pressure of the aqueous solution is used to separate water molecules and impurities to achieve a thorough purification of water quality. The decrease in water production of large-scale reverse osmosis pure water equipment will directly affect the use of users, so here is a brief introduction to the reasons for the decrease in water production of secondary reverse osmosis pure water treatment equipment. 1. Under the same inlet pressure on the water production side, the pressure on the water production side is set, or the water production pipeline is too small, the delivery point is far, and the resistance is large, resulting in a decrease in net pressure and a decrease in water production. 2. The equipment is not maintained in time. Large-scale reverse osmosis pure water equipment lacks corresponding daily maintenance operations, usually quartz sand, activated carbon, and the front-end filter of the softener are not maintained in place, and the security filter element is not replaced in time or even. 3. The pressure difference is normal. For the 6-core 8040 membrane element, the pressure difference between the two sections is about 3~4bar. Unreasonable piping design leads to large pressure loss or incomplete closure of the second-stage concentrated water discharge valve, which will lead to a decrease in net pressure and thus a decrease in water production. 4. The reading error of instruments and meters. Pressure gauges and flow meters are not calibrated before use, and the readings are not accurate. The installation position of the pressure gauge is far away from the two ends of the pressure vessel, and its reading contains the pressure loss of the pipeline, but when it is used as the inlet pressure, the inlet pressure is lower and the water production is lower. 5. The inlet water conductivity (or TDS) is much higher than the design value. For the NaCL solution, the osmotic pressure increases by about 11.4 psi (0.8 bar) for every 1000 ppm increase in TDS. Under the same inlet pressure, the water production will be reduce. The above-mentioned reasons are the main reasons for the reduction in water production of large-scale secondary reverse osmosis pure water treatment equipment. Did you know? The secondary reverse osmosis pure water treatment equipment produced by environmental protection companies will not let you because of the water quality. The purity and trouble. Using advanced reverse osmosis technology, combined with our excellent technical personnel, the large-scale reverse osmosis pure water equipment developed by us is stable and worthy of your peace of mind to buy.
