A: product classification of water purifier:
1) water machine; including pure angel, filter dust cover of pure water machine, water machine (commercial type officedevice),Nongjiale pure water machine (mainly for rural practical), water purification, water purification and angel wizard.Pure water machine manufacturers in Shanghai, Beijing based, these city water machine development started early, main products for the larger coastal cityin northern area and water salinity.
2) ultrafiltration machine; including the energy drink straight water purifier, Gemini, box type straight drink machine, threedrum filter,stainless steel kitchen water purifier etc.. Shenzhen is the ultrafiltration machine development of heaven, has become the country's largest supply base of ultrafiltration device.
3) function machine: including soft water machine, small molecules of water function.
This is the three big classification, and according to the use of concrete can be divided into: kitchen water purifier,kitchen drinking dual-purpose machine, the whole house water purifier, central water purifier, ultrafiltration straight drink machine, pure filter straight drink machine
Other water purifier: pipeline machine, tap water purifier, double drum filter etc..
Two: water purifier has no use: principle of water purifying machine technology
1:microfiltration filtering precision is generally in the 0.1 - 10 micron, a variety of PP filter common, ceramic filter etc. all belong to thescope of the main micro filtration, filter water sediment, rust and other large particle complex. Machines of this type of filtering water can not drink it, mainly to meet the family vegetable washing water of life and so on, this kind of products such as central water purifier, whole house water purifier, etc..
2:ultrafiltration: filtering precision is generally in the 0.001 - 0.1 micron, belong to one of the high and new technology in twenty-first Century. Filter out the iron rust in the water, sediment, suspended matter, colloid, bacteria, high molecularorganic compounds and other harmful substances, some mineral elements and can retain the beneficial. Is the core component of mineral water, mountain spring water in production process. This kind of products such as kitchen water purifier, water purifier, Kitchen God, ultrafiltration instant drinking machine series can be achieved straight drink effect.
3 worry: between sodium; filtration precision between ultrafiltration and reverse osmosis desalination rate of penetration,lower than thereverse, is an ideal filter material, but in its production has not yet formed stable technology, and the cost is relatively high.
4: reverse osmosis filtration precision is about 0.0001 microns separation technology, is an ultra high precision by using thedevelopedAmerican early 60's membrane pressure difference. Which can filter impurities in water (including all the harmful and beneficial), onlyallows water molecules to pass through. But the need for pressurized power, the flow of small, lowefficiency of water utilization.
Three: the role of water purifier
1) kitchen water purifier; mainly for the kitchen purifying water quality and safety protection, remove mountains, bacteria,virus, and polymer chemical pollutants and other harmful substances. Apply to the south, and the north area, sweet water quality, ensure thehousehold water security, water quality is the European bottled mineral water standard:
2) the whole house water purifier for family security needs to solve the safe problem of water, the family, a full range of water purification optimization of water demand, reached the international top clean water solution, purification bath water, kitchen water, alllife demand of drinking water, a full range to solve the drinking water security issues. Usinghousehold water purifier, water purification,clean health safety.
3) ultrafiltration instant drinking machine with advanced technology; separation method, the effective removal of heavy metals, scale,polymer: pollutants, may obtain the high pure water in severe pollution in the environment. Life security worries, exempt from the water pollution problem in any case. By the world recognized as nuclear radiation area, heavy metal pollution, chemical pollutionregional, regional necessary water purification equipment.
4) ultrafiltration water purifier; get rid of scale removal from water, residual chlorine, bacteria, virus, macromolecular organic substance,to ensure the health of human body. In fact, our daily purchase in the supermarket shopping malls of pure water, mineral water, andwe buy bottled water is the use of the regular water purifier, only these water purifier is thehousehold water purifier amplification, the principle is the same, so the water purifier is very useful, and use is also very obvious.
Four: water purifier is useful to understand the local water quality?
Here is a list of quality report of countrywide main city, seen after know the current status of the national water qualityhow bad.
Beijing - the annual discharge of sewage 900000000 T, of which only 10% after decontamination, the city's 83 rivers are polluted.
Tianjin city ---- the annual emission of 394000000 T city waste water, industrial waste water is 280000000 t.
Hebei province Baoding city drainage pipeline ----45% is corrosion, pipeline blockage, a lot of overflow water, sewage discharge and become a "big".
Shanxi province Taiyuan city ---- Taiyuan section of Fenhe River water phenol, cyanide, arsenic, mercury, chromium sixaddicted to drinking,smoking,etc., phenol content exceeds the standard of drinking 2000 times.
Changzhi city ---- Zhang heavily polluted river water, river water of Xiangyuan county were black, many toxic compounds in water and not sink float, chemical oxygen demand exceed the standard 100%
Jincheng ----1986 years ago, more than 70 enterprises Dan River, wastewater discharged into the river each year up to 14970000 T,the 70% polluted river.
Shenyang City, Liaoning Province, a plurality of ----60 plant using natural pits and seepage well discharge of untreated sewage, a direct result of the polluted groundwater.
Jinzhou city ---- Jinzhou Bay is the most serious national mercury polluted area, the seabed sediment mercury contentexceed the standard 11 times.
Qigihar City, groundwater pollution degree is divided into non polluted area (pollution index < 1), light pollution area(pollution index 1.0-3.5), middle polluted area (pollution index (3.5-5.5), heavy pollution area pollution index > 5.5). The city of groundwater, in heavypollution area
