The basic working principle of reverse osmosis is to use a special high-pressure water pump to add the raw water to the pressure of 6-20 kg, so that the raw water can penetrate through the reverse osmosis membrane with a pore size of only 0.0001 ?? m under the action of pressure. Chemical ions, bacteria, fungi and viruses cannot pass through and are discharged with wastewater. Only water molecules and solvents with a volume of less than 0.0001 microns are allowed to pass through.
The security filter is equipped with a filter aperture of 5 ?? M filter element. These filter elements will filter out any size greater than 5 ?? M particles. Protect the downstream RO membrane, otherwise the RO membrane surface is easy to scale. The commonly used permeable membrane is polyamide membrane, and the membrane type is roll composite membrane. The desalination rate of this type of membrane can reach 99.5%.
The filter cartridge is used to filter the raw water into produced water
