The main components of water treatment equipment are:
Original water tank: buffers 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 for the water point.
Quartz sand filter: Multi-layer mechanical filtration of raw water through quartz sand filter can remove mud sand, rust, large particles and suspended solids in raw water, remove insoluble impurities in water and colloid and free chlorine left in water. , odor, chromaticity and some iron and manganese and organic matter in the adsorption water, reduce the SDI value of water.
Activated carbon filter: After the raw water is treated by quartz sand filter, most of the visible objects have been removed, and then the activated carbon filter is used to remove the colloid, free chlorine, odor, color and some iron and manganese retained in the water. Organic matter in water, etc., is an adsorption filtration method.
(softening tank): In order to achieve higher recovery rate and prevent reverse osmosis concentrated water end, especially in the reverse osmosis pressure vessel, carbonate, sulfate and Ca2+, Mg2+ ions appear on the concentrated water side of a membrane element after zui Chemical fouling, 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 to prevent scaling problems on the surface of the RO membrane, and ensure the safe and stable operation of the system.
Security Filter: The purpose of the security filter is to retain particles larger than a few microns from raw water to prevent it from entering the reverse osmosis system. Such particles may be broken down by the high pressure pump and 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. 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 is the reverse process of penetration. There is a membrane in nature called semi-permeable membrane, which can only pass through water and cannot pass through other solutes. If the semi-permeable membrane of fresh water and salt water is separated, fresh water will naturally pass through the semi-permeable membrane to the side of the brine.
EDI device: EDI water treatment device, also known as continuous electric desalination technology, scientifically combines electrodialysis technology and ion exchange technology, through the selection of cations and anions by cation and anion membranes, and ion exchange resin in water. The exchange of ions realizes the directional migration of ions in the water under the action of the electric field, thereby achieving deep purification and demineralization of water, and continuously regenerating the charged resin by hydrogen ions and hydroxide ions generated by water electrolysis. Therefore, EDI water treatment The device water production process can continuously produce high-quality ultra-pure water without regeneration of acid and alkali chemicals. It has the advantages of advanced technology, compact structure and easy operation. It can be widely used in electric power, electronics, medicine, chemical, food and laboratory fields, and is a green revolution in water treatment technology. This new technology can replace the traditional ion exchange device to produce ultrapure water with a resistivity of up to 16-18MΩ·CM.
0.22μm precision filter: The function of the precision filter is mainly used for purifying water, especially in the field where the water quality is required. It is used to remove fine particles in the liquid to meet the requirements of the subsequent process. Sometimes it is also installed in the end of the complete water treatment system to prevent fine particles and broken resin residue from entering the finished water. The deionized water is easily polluted by the overflow pipe and equipment, causing the deionized water conductivity to rise and the water quality is unqualified. Through the 0.2μm precision filter, the particles that may remain in the deionized water are filtered to ensure the purity of the terminal water.
