Stable operation, due to the use of large reverse osmosis equipment components (reverse osmosis membrane and high pressure pump), easy to produce operational failure;
ƒExcellent water quality, desalination rate ≥ 97%;
Fine filter → activated carbon filter → granular carbon filter → high pressure pump → reverse osmosis → rear activated carbon → pure water tank → out of pure water
1、Water Technical parameters: tap water
The composition and principle of the equipment：
Summary of working principle and performance
Reverse osmosis is a semipermeable membrane that allows water to pass through and does not allow solute to pass through the action of pressure difference. The mechanism of its work is hydrogen bond theory and selective adsorption-capillary flow theory. The reverse osmosis membrane is a low pressure composite membrane and an ultra low pressure composite membrane. The structure is a spiral wound membrane, and a bag-shaped reverse osmosis membrane is sandwiched by a layer of porous supporting material. , And the opening of the diversion net and the bag-shaped film is fixed to the porous fresh water centralized tube and the coil is made into a spiral shape, and the outer seal is made of epoxy resin. The advantage is that the unit volume membrane surface area.Water distribution, compact structure. High desalination rate, good retention. Disadvantages are easy to plug, cleaning more difficult, so in the application of water quality pretreatment and cleaning is essential.
The main factors affecting the desalination rate of reverse osmosis membrane：
1、The number of ions is increased with the increase of the ion order, and the desalination rate of the second and third order ions is higher than that of the single order ion.
2、Molecular size: Desalination rate increases with increasing molecular average diameter.
3、Hydrogen bonding trend: For compounds containing strong hydrogen bonds, desalination rate is very low, such as water, ammonia and phenol.
4、Soluble gas: easy to penetrate in its free state, such as CO SO O Cl HS
5、PH value: acidic conditions, although the film is not easy to block, but the desalination rate to decline
6、Raw water concentration: When the raw water concentration is increased, the desalination rate decreases.
7、Water temperature: When the water temperature rises, the desalination rate increases (due to the decrease in water viscosity).
8、Working pressure: When the working pressure is raised, the desalination rate is slightly increased.
