Grade One:

　　1"Overview"

　　Quartz sand filters are used to remove suspended particulate matter from water and reduce the turbidity of the effluent. Activated carbon filters are used to remove color, odor, residual chlorine and organic matter. The water flow direction of the equipment operation adopts a top-down direction, which arranges the particle size of the quartz sand filter material from large to small along the water flow direction. This filtration method can greatly exert the interception effect of each part of the filter material in the filter layer, thereby improving the filtration efficiency. Activated carbon filters are used for advanced treatment of effluent, improving the quality of effluent and enhancing the reliable and stable operation of equipment.

　　2"Characteristics"

　　a.It has a large filtration surface and a high removal rate, providing necessary protection for the subsequent water treatment system.

　　Grade 2:

　　1Working principle:

　　DHThe iron and manganese removal device uses oxidation methods to oxidize low-valent iron ions and low-valent manganese ions in water into high-valent iron ions and high-valent manganese ions, and then removes them through adsorption and filtration, achieving the goal of reducing the iron and manganese content in water. The filter material adopts refined quartz sand or manganese sand.

　　2Usage:

　　It is widely used in the pretreatment of mineral water and pure water for iron and manganese sedimentation, as well as in the early water treatment for iron and manganese removal in geothermal projects and swimming pool projects.

　　Large-scale fully automatic magnetic separator

　　The fully automatic magnetic separator designed and manufactured is highly efficient in automation and iron removal, and has been successfully applied in iron removal projects of high-iron water across the country. Stainless steel filter cartridges can be adoptedPPDifferent materials such as cotton, nylon and melt-blown are used as filter elements to remove tiny suspended solids and other impurities in water, making the raw water quality meet the feed water requirements of reverse osmosis membranes.

　　Iii. Level Three:

　　1Resin function:

　　By taking advantage of the ion exchange property of cation resin, calcium and magnesium ions in tap water are displaced and adsorbed, greatly reducing the hardness of the raw water and achieving the purpose of softening. This eliminates the problems such as scaling, hard towels and poor taste caused by the high hardness of tap water. Food-grade cation exchange resin: It can reduce the hardness of raw water,Avoid causing stones.

　　2Service life:

　　Since cation resin cannot infinitely replace and adsorb calcium and magnesium ions, every time it is used7～10Days or the volume of water to be treated1For about one ton, the resin filter element needs to be removed and placed in a concentration of10％Soak in salt water2～3It takes about an hour for the cation resin to be regenerated in sodium chloride (salt), and this cycle can be reused8～10About a month;

　　Four. Fourth level:

　　1Coconut shell activated carbon filter element

　　Activated carbon is widely used in petrochemicals, gold refining, water purification and air purification. Its effective effect mainly depends on the rich pores produced by the steam burning in the carbon body during the activation process. The specific surface area of coconut shell activated carbon is generally greater than1500M2/gIt's bamboo charcoal2～3It's made of charcoal10～20Double. That is to say, in an activated carbon particle the size of a grain of rice, the inner surface area of the micropores is equivalent to the size of the inner wall of a large living room. It is precisely these micropores that enable activated carbon to "capture" various toxic and harmful gases and impurities. During World War I, the German army used poison gas for the first time in combat, and the world's first gas masks made of activated carbon also came into being. With the advent of the third pollution period marked by "indoor air pollution", urban residents are increasingly yearning for and craving pure air, and various activated carbon products are entering thousands of households. It has a powerful retention effect on organic matter and inorganic colloids in water, and can remove the taste, odor, residual chlorine and decolorize in water, making the water sweeter and more palatable.

　　V. Level Five:

　　Stainless steel multi-core security filter

　　Stainless steel filter cartridges can be adoptedPPCotton is used as a filter core to remove tiny suspended solids and other impurities in water, making the raw water quality meet hygiene standards. It can be used in hotels, schools, factories, beverage factories and households to prepare cold drink water and beverages, as well as as a pure water preparation unit device. Multiple microporous filter elements can be assembled (lengths are optional)1040Different specifications (in inches), suitable for larger or higher flow rates. The filter can be installed.10"Inch"40There are various sizes available. The flow is large and accessible600t/hThat's all. The internal filter element sockets of a multi-core filter are generally222Type. The connection of the cylinder can be of flange type or clamp type, generally greater than5All the core filters are connected by flanges. The connection of the inlet and outlet pipes generally adopts quick-opening or flange connection, and can also be customized according to customer requirements.
