Reverse osmosis system Mide Crystal is a five-stage system for obtaining high-purity drinking water. Capacity-up to 280 l / day. The package includes a booster pump. The principle of operation is traditional for reverse osmosis filters and consists in dividing the source water with a semipermeable membrane into two streams: purified water — permeate and water with a high content of impurities — concentrate, which is discharged into the sewer. The pore size of the membrane does not exceed 0.0001 microns, and the size of most dissolved impurities, as well as bacteria and viruses, is much larger, so they do not pass through the membrane. The system works stably even at low pressure in the supply line, thanks to the presence of a pressure boosting pump in the package.
