A complete Liquid Filters includes these components.

Raw water tank: plays a buffer role in the supply of raw water, coordinates the supply of raw water and the input of the raw water pump

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

Quartz sand filter: The raw water is filtered through the multi-layer mechanical filtration of the quartz sand filter, which can filter out mud, sand, rust, large particles and suspended solids in the raw water, and can remove insoluble impurities in the water and colloids and free chlorine remaining in the water , odor, chroma, and some iron and manganese and organic matter in the adsorbed water, etc., reducing the SDI value of water.

Activated carbon filter: After the raw water is treated with a quartz sand filter, most of the visible matter has been removed, and then the colloid, free chlorine, odor, chroma, and some iron, manganese and adsorption in the water are removed through the activated carbon filter Organic matter in water, etc., belongs to the adsorption filtration method.

(Softening tank): In order to achieve a higher recovery rate and prevent the reverse osmosis concentrated water end, especially the concentrated water side of the last membrane element in the reverse osmosis pressure vessel, the chemical reaction of carbonate, sulfate and Ca2+, Mg2+ ions Scaling will affect the performance of membrane elements. The softening device can completely remove the hardness of calcium and magnesium ions in the water and protect the reverse osmosis membrane to prevent scaling on the surface of the RO membrane and ensure the 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 the particles are accelerated by the high-pressure pump, they may penetrate the reverse osmosis membrane module, 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, it is necessary to provide pressure to the RO membrane from the outside. This pressure is the pressure required for the normal operation of the RO membrane. This pressure is provided by the high-pressure pump.

Reverse osmosis membrane: Reverse osmosis is actually the reverse process of osmosis. In nature, there is a membrane called a semi-permeable membrane, which can only pass through water but not other solutes. If the semi-permeable membrane between fresh water and salt water is separated, the fresh water will naturally pass through the semi-permeable membrane to the salt water side.

EDI device: EDI water treatment device is also called continuous electric desalination technology. It scientifically integrates electrodialysis technology and ion exchange technology. The exchange of ions realizes the directional migration of ions in water under the action of an electric field, so as to achieve the deep purification and desalination of water, and the hydrogen ions and hydroxide ions generated by water electrolysis can continuously regenerate the filling resin, so EDI water treatment The water production process of the 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 easy operation. It can be widely used in the fields of electric power, electronics, medicine, chemical industry, food and laboratories. It is a green revolution in water treatment technology. This new technology can replace traditional ion exchange devices to produce ultrapure water

Precision filter: The function of precision filter is mainly used for water purification, especially in areas with high water quality requirements, to remove fine particles in liquid to meet the requirements of subsequent processes for water inflow. Sometimes it is also installed at the end of the complete water treatment system to prevent fine particles and broken resin residues from entering the finished water. The deionized water is easily caused by secondary pollution by the overflow pipes and equipment, resulting in an increase in the conductivity of the deionized water. The water quality is unqualified. Through the 0.xn--1m-99b precision filter, the particles that may remain in the deionized water are filtered out to ensure the purity of the terminal water.
