Easily Help You Understand The Process And Function Of Water Treatment Equipment

Raw water tank: It plays a buffering role in the supply of raw water, coordinating the supply of raw water with the input of the raw water pump

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

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

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

(Softening tank): In order to achieve a higher recovery rate and prevent chemical scaling of carbonate, sulfate, 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, and prevent scaling problems on the surface of the RO membrane, ensuring safe and stable operation of the system.

Security filter: The function of a 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 a high-pressure pump, these particles may penetrate 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 the RO membrane, external pressure is required to provide pressure to the RO membrane, which is the pressure required for the normal operation of the RO membrane. This pressure is provided by the high-pressure pump.

Reverse osmosis is actually the reverse process of infiltration. There is a type of membrane in nature called a semi permeable membrane, which can only pass through water and cannot pass through other solutes If freshwater and saltwater are separated by a semi permeable membrane, freshwater will naturally pass through the membrane to the saltwater side.

EDI device: EDI water treatment device, also known as continuous electric desalination technology, scientifically integrates electrodialysis technology and ion exchange technology. Through the selective permeation of cations and anions by cation and anion membranes and the exchange of ions in water by ion exchange resin, the directional migration of ions in water is achieved under the action of an electric field, thus achieving deep purification and desalination of water. The hydrogen ions and hydroxide ions generated by water electrolysis continuously regenerate the loaded resin. Therefore, the water production process of EDI water treatment device can continuously produce high-quality ultrapure water without the need for acid or alkali chemical regeneration. It has the advantages of advanced technology, compact structure, and easy operation, and can be widely applied in the fields of power, electronics, medicine, chemical industry, food, and laboratory. It is a green revolution in water treatment technology. This new technology can replace traditional ion exchange devices and produce ultrapure water with a resistivity of up to 16-18M Ω· CM

0.22 μ m precision filter: Precision filters are mainly used for purifying water, especially in areas with high water quality requirements, to remove small particles from liquids to meet the requirements of subsequent processes for incoming 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 overcurrent pipelines and equipment, resulting in an increase in conductivity and substandard water quality. Through a 0.2 μ m precision filter, any particles that may remain in the deionized water are filtered out to ensure pure water quality at the end.
