Reverse osmosis water purifier principle: the use of semi-permeable membrane technology to achieve the separation of water and solutes, the core component is reverse osmosis membrane.
Reverse osmosis water purifier is a set of water purification system, mainly composed of filters and reverse osmosis devices, as well as dosing and disinfection devices. Its working principle is to use semi-permeable membrane technology to realize the separation of water and solute, and its core component is reverse osmosis membrane. Reverse osmosis water purifier can block all dissolved salts and molecular weight greater than 100 organic matter, but allows water molecules through, reverse osmosis composite membrane desalination rate is generally greater than 98%. The use of reverse osmosis purified water can be used for cooking, soup, tea, coffee, to ensure the original flavor.
It should be noted that the equipment for reverse osmosis water treatment is more expensive, and the maintenance and replacement of semi-permeable membranes and other components are also more troublesome. Therefore, when choosing water treatment equipment, you need to choose according to the actual situation and needs.
Reverse osmosis water purifier use precautions
1, the ph value of the water: equipment operation, pay attention to the ph value of the water changes, the reason for this, the hydrolysis of cellulose acetate membranes will affect the performance of the device, the ph value of the feed water should be controlled to be within the range of 3 to 11.
2, the equipment environment temperature: in the northern winter, the temperature drops, the raw water temperature decreases, there may be low water production, water production does not meet the standard, if the equipment continues to operate, should remember to give the equipment to add temperature, to prevent the pipeline freezing and cracking; if the winter does not operate, the reverse osmosis membrane is removed and placed indoors, to prevent icing.
3, pressure: pay attention to the continuous operation of the high-pressure pump. Reverse osmosis inlet pressure to maintain a proper margin, otherwise due to the lack of compaction, the rate of desalination will be reduced. Reverse osmosis device should be stopped when the low-pressure feed water to replace the water in the reverse osmosis device.
