The main components of water treatment equipment include:

Raw water tank: acts as a buffer for the supply of raw water, coordinating the supply of raw water with the input of the raw water pump.

Raw water pump: Provide sufficient pressure and water volume for the water consumption point.

Quartz sand filter: The raw water is filtered through multiple layers of mechanical filtration through the quartz sand filter, which can remove mud, rust, large particles, and suspended solids in the raw water. It can remove insoluble impurities and residual colloids, free chlorine, odors, chromaticity, as well as some iron, manganese, and organic matter adsorbed in the water, reducing the SDI value of the water.

Activated carbon filter: After the raw water is treated with a quartz sand filter, most of the visible substances are removed, and then the remaining colloids, free chlorine, odors, chromaticity, as well as some iron, manganese, and organic matter adsorbed in the water are removed through the activated carbon filter. This belongs to the adsorption filtration method.

Softening tank: In order to achieve higher recovery rate and prevent chemical scaling of carbonate, sulfate and Ca2+, Mg2+ions on the concentrated water side of the last membrane element in the reverse osmosis pressure vessel, especially on the concentrated water side, which affects the performance of the membrane element, the softening device can completely remove the hardness of calcium and magnesium ions in the water, protect the reverse osmosis membrane, prevent scaling on the surface of the RO membrane, and ensure safe and stable operation of the system.

Security filter: The function of the security filter is to intercept particles larger than a few microns brought by raw water to prevent them from entering the reverse osmosis system. After being accelerated by the high-pressure pump, these particles may puncture the reverse osmosis membrane components, causing a large amount of salt leakage and scratching the impeller of the high-pressure pump.

High pressure pump: in order to overcome the Osmotic pressure of RO membrane, the outside world needs to provide pressure for RO membrane. This pressure is the pressure required for the normal operation of RO membrane. This pressure is provided by the high pressure pump.

Reverse osmosis: Reverse osmosis is actually the reverse process of infiltration. There is a kind of membrane in nature called Semipermeable membrane, which can only pass through water and cannot pass through other solutes. If the Semipermeable membrane of fresh water and salt water is separated, fresh water will naturally pass through the Semipermeable membrane to the side of salt water.

EDI device: EDI water treatment device, also known as continuous electro desalting technology, scientifically integrates Electrodialysis technology and ion exchange technology, and realizes the directional migration of ions in water under the action of electric field through the selective permeation of cation and anion membranes to cation and anion and the Exchange interaction of ion exchange resin to ions in water, so as to achieve the deep purification and desalination of water, The filling resin is continuously regenerated by the hydrogen ion and Hydroxide ion ion generated by Electrolysis of water, so the water preparation process of EDI water treatment device can continuously produce high-quality Ultrapure water without the regeneration of acid and alkali chemicals. It has the advantages of advanced technology, compact structure and simple operation, and can be widely used in power, electronics, medicine, chemical industry, food and laboratory fields. It is the Green Revolution of water treatment technology. This new technology can replace the traditional ion exchange device to produce Ultrapure water with a resistivity of 16-18M Ω · CM

Zero point two two μ Precision filter: Precision filter is mainly used for purifying water, especially in areas with high water quality requirements, to remove small particles in liquid to meet the requirements of subsequent processes for inlet water. Sometimes it is also installed at the end of the entire water treatment system to prevent small particles and broken resin residues from entering the finished water. Deionized water is prone to secondary pollution caused by flow pipes and equipment, resulting in an increase in conductivity of the water and unqualified water quality μ M precision filter, filtering out possible residual particles in deionized water, ensuring the purity of the terminal water quality.
