One stage reverse osmosis system:
After the coarsely filtered water passes through the reverse osmosis membrane, it is a first-order reverse osmosis. The reverse osmosis membrane is a semi-permeable membrane, which can prevent large ions such as Ga2 +, Mg2 +, Fe-2, SO4-2, Cl-1, Na + from passing through. To ensure the effect of reverse osmosis and protect the reverse osmosis membrane, the scale inhibitor must be continuously added to the reverse osmosis container. At the same time, the water temperature must be above 25 ° C (using a steam heat exchanger in winter) and a certain water pressure. (Pump) Under a certain pressure, ion-containing water is squeezed through the reverse osmosis membrane to form two kinds of water. The water that passes through the reverse osmosis membrane, that is, the finished water, enters the next link, and the water that does not pass through the reverse osmosis membrane is discharged After the first-stage reverse osmosis treatment, the water enters the next stage-the second stage reverse osmosis.
Two stage reverse osmosis system:
The principle of the second-stage reverse osmosis is the same as that of the first-stage reverse osmosis. Its role is to further remove the salt in the water. After reverse osmosis, the water quality conductivity can approach 1MΩ.CM. After the first and second stage reverse osmosis pretreatment, the last remaining water becomes the feedwater of EDI, and the water (concentrated water) that has not passed through the reverse osmosis membrane is discharged in time. The ratio is generally 1: 3, which means that each ton produced Of qualified water, about 3 tons of concentrated water (reclaimed water) should be drained.
EDI (Electro deionization) processing:
The secondary reverse osmosis water is stored in the intermediate water tank, and more than 99% of its ions have been removed. However, to further improve the water quality and produce ultrapure water, the trace elements and CO2 dissolved in the water must also be passed through electricity. Dialysis, or EDI treatment, has the following principles. EDI, or continuous electrosalt removal, uses mixed ion exchange resins to adsorb anions and cations in water. At the same time, these adsorbed ions pass through anion and cation exchange under the action of DC voltage. The film is removed. In this process, the ion exchange resin is continuously regenerated electrically, so it is not necessary to use acid and alkali to regenerate it. This technology can replace traditional ion exchange devices and produce ultra-pure water with a resistivity of up to 18MΩ.CM. This process technology is known as a revolution in the water treatment industry. Compared with traditional ion exchange, EDI has the following advantages: EDI does not require chemical regeneration; EDI does not require downtime during regeneration; provides stable water quality; low energy consumption; easy operation, low labor intensity, and low operating costs.
