　　Water is a kind of new way of drinking water in our country, to drink, soup, cooking and so on the entrance to the drinking water and bathing, flush the toilet and laundry life sanitary water separate, each with different pipeline supply respectively;Among them, the life sanitary water using ordinary tap water, drinking water is ordinary tap water as water source, the depth of purification treatment of high quality drinking water, its characteristic is to remove the water source of water pollutants, disinfection by-products, tap water pipe network of secondary pollutants harmful substances, such as direct raw drink without boiling, therefore, also known as the pipeline direct drinking water, the water quality clean, oxygen enrichment, and active is more beneficial to human body health.
　　Scope of application:
　　Living community, office buildings, hotels, hotels, schools, factories, etc.

School terminal water supply system

　　The system advantages:
　　1.Good water quality, water quality of effluent water quality reach drinking water purification standard, can be directly drinkable.
　　2.To avoid the secondary pollution of water quality: the system closed to run automatically, regular cycle of sterilization, no water, make the pipe to avoid the secondary pollution in the process of water.
　　3.Convenient and affordable: pipeline direct drinking water system easy to use, cheap, solved the high price of bottled water, inconvenient transportation problem.
　　System principle:
　　Water is also called the "dual water supply", is refers to according to different needs in the life of water, water supply all the way that the use of special process, ordinary tap water will be carry on the processing, processing can be directly drinking pure water, and then by a special pipeline to the door, and separate measurement.One water supply is the untreated ordinary tap water, is used for washing, bath, cleaning, etc., using ordinary pipeline measurement.This direct drinking pure water, pure water or water purification according to the definition of GB17323 standards of the People's Republic of China, namely, namely to meet hygienic standards for drinking water water as raw material, through the reverse osmosis method, and other appropriate processing method, the seal in the container and do not contain any additives can direct drinking water, known as the pure water.Standards issued by the ministry of construction CJ94 drinking water purification, water also conform to the hygienic standards for drinking water as raw material, through the hollow fiber ultrafiltration membrane after purification, through special pipe into every household to drink, known as clean water.Due to its pure quality, the entry is filled, this is unmatched by other water, very suitable for the need of modern cities.
　　Pure water manufacturing method there are four basic: distillation, electrodialysis method, ion exchange method and reverse osmosis (RO).
　　1.Distillation is by heating the water vaporization, again the process of condensed liquid;
　　2.Ion exchange method for chemical displacement principle;
　　3.The electrodialysis method is based on physics and chemistry to produce pure water.
　　(the above three methods of water making process and equipment are complex, high energy consumption.)
　　4.Reverse osmosis technology is the most advanced, the most energy saving, high efficiency separation technology.Its principle is under the pressure of osmotic pressure above the solution, by only allowing water molecules through the interception effect on the choice of reverse osmosis membrane, the solution of the solute and solvent separation, so as to achieve the aim of pure water.Reverse osmosis membrane is a highly ordered matrix structure of polymerization of cellulose.Its pore size is 1 (0.1 nm) to 10 (1 nm), or ten billionth of a meter (about one over one thousand of the size of escherichia coli, one percent of the virus).Use of reverse osmosis membrane separation properties, can effectively remove salt dissolved in water, colloid, organic matters, such as bacteria and viruses.
　　Process (process flow diagram attached) :
　　Tap water into the original water tank, the booster pump (one case) to pure water purification processing unit;Pure water unit:
　　(1).Many medium filter, filter the impurities in water;
　　(2).Activated carbon filter, filter out the water chemical organics, heavy metals, chromaticity, odor, etc.;
　　(3).Cation exchanger reduce the hardness of water, salt barrel is for recycled resin configuration;
　　(4).After three pretreatment of the water by reverse osmosis RO before host, producing pure water, net into the water tank;
　　(5).The water by ultraviolet disinfection processor.
