Pure water equipment mainly adopts reverse osmosis membrane technology. Its working principle is to apply a certain pressure to water, allowing water molecules and ionic mineral elements to pass through the reverse osmosis membrane, while most inorganic salts (including heavy metals), organic substances, as well as bacteria and viruses dissolved in water cannot pass through the reverse osmosis membrane. Thus, the purified water that has passed through and the concentrated water that cannot pass through are strictly separated. The pore size on the reverse osmosis membrane is only 0.0001 microns, while the diameter of viruses is generally 0.02 – 0.4 microns, and the diameter of ordinary bacteria is 0.4 – 1 micron.
(1) Reverse osmosis is a physical method without phase change to desalinate saline water at room temperature. The desalination rate of ultra – thin composite membrane elements can reach over 99.5%, and it can simultaneously remove colloids, organic substances, bacteria, viruses, etc. in water;
(2) Using high – quality reverse osmosis membranes, the desalination rate is high, the service life is long, and the operation cost is low;
(3) Adopting a fully automatic pretreatment system to realize unmanned operation;
(4) Using high – quality booster pumps, which are efficient, low – noise, stable and reliable;
(5) Online water quality monitoring and control to real – time monitor water quality changes and ensure water quality safety;
(6) Fully automatic electrical control program, making operation and use more convenient;
(7) Personalized design according to local water quality to meet needs in all aspects;
(8) The equipment has a small footprint and requires little space;
(9) The reverse osmosis device has a high degree of automation, with little work for operation, maintenance and equipment maintenance;
(10) The treatment of water only relies on the pressure of water as the driving force, and its energy consumption is the lowest among many treatment processes;
(11) Using a large amount of chemical agents and acid – base regeneration treatment, there is no chemical waste discharge and no environmental pollution;
(12) Reverse osmosis can produce water continuously. The system is simple, easy to operate, and the product water quality is stable.
