Electronic ultrapure water equipment process flow:
1, the first level of pretreatment system: the use of quartz sand multi-media filter, the main purpose is to remove the source water contains sediment, rust, colloidal substances, suspended solids, such as particles in the 20 m or more harmful substances, the system can be automatically (manually) for the backwash, rinse, etc. A series of operations.
2, the second level of pretreatment system: the use of shell activated carbon filter, the purpose is to remove the pigment in the water, odor, biochemical organics, reduce the residual chlorine value of water and pesticide contamination and other pollutants harmful to the human body. The system can automatically (manually) backwash, positive flushing and a series of other operations.
3, the third level of pretreatment system: the use of positive resin to soften the water, mainly to reduce water hardness, remove calcium and magnesium ions in the water (the main component of scale formation), can effectively extend the service life of the reverse osmosis membrane, and can be intelligent resin regeneration.
4, the fourth level of pretreatment system: the use of 5um pore size precision filters, so that the water is further purified, so that the turbidity and chromaticity of the water to optimize. Ensure that the RO system water intake conditions, to ensure that the quality of the water produced by the equipment, to extend the service life of the equipment.
5, reverse osmosis (ultrafiltration) equipment host: reverse osmosis (ultrafiltration) technology for in-depth desalination (imported U.S. reverse osmosis membrane) to remove calcium, magnesium, lead, mercury and other heavy metals harmful to the human body and other impurities, reduce the hardness of the water, the rate of desalination of 99% or more, the production of pure water to meet national standards.
6, micro-filtration device: the installation of the device is mainly to prevent particles of resin particles from filtering out the cloth water, resulting in secondary water pollution, which is mainly used in the water quality of particularly high occasions.
7, sterilization system: the use of ozone generator (or ultraviolet sterilizer), to reduce the secondary pollution of bacteria, sterilization rate of up to 99% or more, while the ozone dissolved in the water to form oxygen-rich water, to ensure that the water is pure and fresh. Adopting water-air mixer to make ozone fully mixed with water to achieve the best concentration ratio.
Ultra-pure water equipment using reverse osmosis system + EDI process. Quartz sand filter and security filter constitute the pretreatment system, quartz sand filter to remove suspended solids and bacteria, viruses and other pollutants in the raw water, through the security filter further filtration, to ensure that the reverse osmosis system of water quality. The water entering the reverse osmosis system is processed, and the large molecules are removed, so that it enters the EDI treatment unit, and the electrodesalination can remove more than 90% of the ions in the water, so that the water quality reaches the standard of ultrapure water, which is in line with the requirements of production.
