1Multi-media filtration 

       Multi-media filtration: It mainly involves coarse filtration of tap water to prepare it for entering the reverse osmosis membrane, ensuring that the water quality reaches a certain level before entering the reverse osmosis membrane, thereby protecting the usage effect and service life of the reverse osmosis membrane. This process involves filtering the tap water from the raw water tank through fine sand, activated carbon and precision filters to remove impurities, organic matter, colloids, suspended solids and other substances in the water, preventing these large particles from entering the reverse osmosis membrane and clogging it. After coarse filtration, the water quality has improved to a certain extent and is allowed to proceed to the next stage.

2First-stage reverse osmosis

        The water that has undergone coarse filtration and then passes through a reverse osmosis membrane becomes the first-stage reverse osmosis. The reverse osmosis membrane is a semi-permeable membrane and can preventGa2+,Mg2+,Fe-2 ,SO4-2,Cl-1,Na+When large ions pass through, to ensure the effect of reverse osmosis and protect the reverse osmosis membrane, continuously add scale inhibitors to the reverse osmosis container, while ensuring that the water temperature remains constant25℃Above, (in winter, a steam heat exchanger is used) and a certain water pressure is ensured. (A vertical pump is used) under a certain pressure, ionized water is squeezed through the reverse osmosis membrane, thus forming two types of water. All the water that passes through the reverse osmosis membrane is the finished water and enters the next stage, while the water that does not pass through the reverse osmosis membrane is discharged. The water that has undergone the first-stage reverse osmosis treatment then enters the next stage - the second-stage reverse osmosis. 

3Secondary reverse osmosis 

       The principle of secondary reverse osmosis is the same as that of primary reverse osmosis. Its function is to further remove salt from water.Ga2+,Mg2+,Fe-2 ,SO4-2,Cl-1,Na+Plasma further improves water quality. After secondary reverse osmosis, the conductivity of the water can approach1MΩ.CM. After the first and second stages of reverse osmosis pretreatment, the water retained later becomesEDIThe feed water that has not passed through the reverse osmosis membrane (concentrated water) is discharged in a timely manner, and the proportion is generally1:3That is, for every ton of qualified water produced, approximately3One ton of concentrated water (reclaimed water). 

4,EDI(Electro deionization"Processing" 

       The water that has undergone secondary reverse osmosis is stored in an intermediate water tank, which99%The above-mentioned ions have been removed, but to further improve water quality and produce ultrapure water, the trace elements dissolved in water andCO2It also goes through electrodialysis, that isEDIThe principle of processing is as followsEDIContinuous electro-deionization is a process in which mixed ion exchange resins adsorb cations and anions in the feed water. Meanwhile, under the action of direct current voltage, these adsorbed ions pass through the cation and anion exchange membranes respectively and are removed. During this process, the ion exchange resin is continuously regenerated by electricity, so there is no need to regenerate it with acid or alkali. This technology can replace traditional ion exchange devices and produce products with a resistivity as high as18MΩ.CMUltra-pure water. This technological process is regarded as a revolution in the water treatment industry. Compared with traditional ion exchange,EDIIt has the following advantages:EDINo chemical regeneration required;EDIThere is no need to stop the machine during regeneration. Provide stable water quality; Low energy consumption; Easy to operate and with low labor intensity. Low operating costs.
