A complete water treatment system consists of three main parts: pre-treatment system, precision treatment system, and post-treatment system. Raw waterPPAfter pre-treatment systems such as filter cartridges (sand rod filters), activated carbon units, and water softener units, the content of suspended solids (particulate matter), colloids, organic matter, hardness, microorganisms, and other impurities in the water is greatly reduced to reduce the processing load of subsequent precision treatment systems such as reverse osmosis and electric desalination, and extend their service life.
Analysis of Industrial Pure Water Equipment System Units
PPfilter element
Material: Polypropylene hot melt fiber filter cartridge.
Characteristics:10μmFilter holes can intercept particulate matter in water (such as sediment and rust commonly found in tap water), reduce turbidity, but cannot filter out bacteria and ionic substances.
Specifications:10Inch（250㎜）/20Inch（500㎜）.
Activated carbon unit
Activated carbon has a large specific surface area and is covered with extremely small pore sizes（10～30The micropores of E have a significant adsorption and filtration effect on organic colloids, residual chlorine, iron ions, etc. Commonly used desktop pure water machines, water purifiers, etc10inch/20Inch activated carbon filter cartridge. Glass fiber reinforced plastic commonly used in large pure water units/Activated carbon filter canister made of stainless steel material.
Softener unit
Large and medium-sized pure water systems often use fully automatic water softeners to remove calcium and magnesium ions from raw water. The fully automatic water softener consists of a sodium ion resin tank, a regeneration salt tank, and multiple control valves, which can be programmed to control operation and automatically regenerate (time type)/There are two control methods for flow type. During regeneration, the siphon principle is used to absorb salt, and then water is injected to hydrate the salt. The regeneration time is usually2hour
Small desktop pure water machines are generally used10inch/20Inch soft water resin filter to reduce the hardness of raw water.
reverse osmosis unit
RO（Reverse Osmosis）Reverse osmosis technology is a membrane separation and filtration technology that uses pressure gauge difference as power. It originated from the research of aerospace technology in the 1960s in the United States and gradually transformed into civilian use. Currently, it has been widely used in scientific research, medicine, food, beverage, seawater desalination and other fields.
ROThe pore size of reverse osmosis membrane is as small as the nanometer level（1nano=10-9Under certain pressure,H2OMolecules can pass throughROMembrane, while impurities such as inorganic salts, heavy metal ions, organic matter, colloids, bacteria, viruses, etc. in the source water cannot pass throughROThe membrane strictly distinguishes between pure water that can pass through and concentrated water that cannot pass through.
ROMembrane responds to high valence ions, colloids, bacteria, and molecules with a molecular weight greater than300 daltonThe removal rate of organic substances (including heat sources) is as high as99%Above, for low-priced ions（NA+TheK+）Removal rate reaches95%When the conductivity of the source water<3505µs>，ROThe conductivity of pure water is usually≤55µs/cmMeets the national third level water use standards. After circulating and filtering through atomic level ion exchange columns, the effluent rate can reach18.2MΩ.cm. The reverse osmosis method is achievable90%～99%impurity removal rateZThe economic approach is also a reagent grade ultrapure water systemPre processing methods. Remarks:ROThe filtration capacity of the membrane is greatly affected by water temperature,ZThe suitable water temperature is25℃～30℃The temperature drops1℃，ROThe water production of the membrane decreases approximately3%When the water temperature approaches0℃When,ROThe membrane will stop producing water.
Ultrafiltration unit
Ultrafiltration membrane, also known as hollow fiber ultrafiltration membrane. The pore size is between reverse osmosis and microfiltration, approximately0.01～0.1μmIt is commonly used as a post-treatment device for pure water systems, which can be used to intercept various particles, macromolecular solutes, bacteria, viruses, pyrogens, etc. in the solution. The pore size of ultrafiltration membrane is determined by retention test of substances with a certain molecular weight, and expressed as the numerical value of molecular weight. The molecular weight of ultrafiltration membrane that can filter out heat source is usually6000Dalton（dalton）.
UV meter unit
Ultraviolet light is a type of light wave that is invisible to the naked eye and exists on the outer side of the ultraviolet end of the spectrum, hence it is called ultraviolet light. According to different wavelength ranges, it is divided intoATheBTheCThree types of bands, among whichCThe wavelength of ultraviolet radiation in the band 240 －260nmBetween them, forZEffective sterilization band, wavelength within the bandZStrong point is253.7nm.
UV sterilizer 304 or316LStainless steel as the main material, high-purity quartz tube as the sleeve, combined with high-performance quartz ultraviolet low-pressure mercury disinfection lamp tube, has the advantages of strong sterilization power, long service life, stable and reliable branch, and its sterilization efficiency≥ 99%The service life of imported light tubes≥ 9000hour
Characteristics of UV sterilization:
1.UV sterilization is fast, efficient, and effective.
2. Ultraviolet radiation does not alter the physical and chemical properties of water, and does not contaminate pure water by introducing additives.
3. Suitable for various water flow rates, easy to operate, convenient to use, just need to regularly clean the quartz glass sleeve and replace the lamp tube.
4. Small size, lightweight, and low power consumption.
5. UV sterilization does not have a continuous disinfection effect and is susceptible to secondary pollution.
Purification column unit
