RO function and structure of household water

Pure water machine manufactured not only for everyday drinking, tea, coffee, powdered milk, cold drink, etc., directly to drink better, out of crystal clear ice cubes made with pure, clean, pure water also can be used for steamed rice, soup, porridge, etc., to make the food taste pure, raw fruits and vegetables when you need the best final again washed with pure water, eat more at ease, water will not irritate the skin, if you use it wash, can play the role of beauty.


Reverse osmosis water purification system is based on reverse osmosis water machine core, the part before the reverse osmosis membrane can be called pre-treatment, post-treatment after the reverse osmosis membrane is called, the following points were its Shao :
 
     1, pre-treatment

Pre-treatment is the primary raw water purification, provide water for the reverse osmosis membrane. Its main role is to protect the reverse osmosis membrane. Pre-treatment levels, the filter must have: precipitation filter, activated carbon filter.
 
Precipitation filter, also known as PP (polypropylene) meltblown cotton, its filtration accuracy μm micron level, the main role is to remove the raw water rust, sediment, suspended solids and other large particles of impurities. By precipitation purification filter raw water to meet the basic colorless, no visible thing that prevents the reverse osmosis membrane is blocked.

Pre-activated carbon core not only raw water to remove odor, odor, but also for water turbidity, color, organic matter, iron, phenol, F, As, Hg, Al, CHCl3, CCL4, chlorine and other obvious lowering effect. By removing the chlorine in tap water, to prevent oxidation of strong chlorine damage to the reverse osmosis membrane.

Pre-treatment can also increase the required resin filter to reduce the hardness of the raw water, to prevent fouling of the reverse osmosis membrane surface.

     2, reverse osmosis and reverse osmosis membranes

Penetration is a natural phenomenon, refers solvent in the solution through a semipermeable membrane, to the high-concentration solution is transferred from the lean solution phenomenon.

Reverse osmosis, also known as reverse osmosis, as opposed to penetration phenomenon, is a man-made phenomenon. Refers to reverse osmosis under pressure, high concentration solution of a solvent through a semipermeable membrane to a low concentration solution of the phenomenon.
 
In order to achieve the reverse osmosis membrane is a reverse osmosis phenomenon, the use of a semipermeable membrane special process synthesis. It can remove large particles of impurities in the water, colloids, microorganisms, organic compounds, heavy metals, etc., on dissolved solids (salts) also have a higher removal rate. After treatment by reverse osmosis membrane can be safe, hygienic pure water.

     3, after treatment

Treated water machine can be activated carbon filter, UV sterilization lamp.

The role of the post carbon filter is to manufacture reverse osmosis membrane water depth treatment, removal of volatile organic compounds, odors, improve the taste of pure water. In particular, the use of pressure-type storage tank water machine, activated carbon can effectively remove the rear storage tank produced rubber smell.
 
     UV sterilization lamp often use high-grade pure water, pure water is to prevent secondary pollution.

     4, the booster and the control system

Because of the raw water pressure reverse osmosis membrane needs 0.4-0.8MPa, so water water purification system must be installed in a special booster. Booster generally use 24V DC power supply, the water level is controlled by a switch or pressure switch.
