Enforfable and Technical Proposal of Shengyang Livng Pipeline Direct Dringking Water

　　Enforfable and technical proposal of shengyang livng pipeline direct dringking water – shenyang direct dringking water equipment- shenyang pipeline water treatment equipment

　　Real production and relevant potos of pipeline direct dringking water system

　　I. Application scope:

　　This equipment can be supplied office buildings, hotels, guest houses, apartments, star hotels, upscale residential area, schools, troops and factories etc. with high quality direct dringking water.

　　II. Systematic summary:

　　Direct dringking water system is consisted of raw water tank, pre-treatment unit, host membrane treatment unit, cyclical constant voltage frequency conversion water supply unit, disinfection unit and auto control unit.

　　(1). Water treatment system

　　Water purification equipment is the core device in the whole direct dringking water system.

　　Pre-treatment system - - quartz sand filtration, active carbon adsorption, softening treatment, microfiltration and so on. The chief roles are romoving glues, organic substances, bacteria free chlorine etc, which is to meet the input water requirements of following membrane treatment system.

　　Membrane filtration system - - according to the condition of raw water and the requirements of water quality, nanofiltration and RO can be used. This system can remove glues, suspended solids, heavy metal, microorganism and so on.

　　(2). Post-treatment system

　　Post-treatment system includes sterilization and disinfection. In rare cases, mineral substances adding devices would be needed.

　　The basic requirements for sterilization and disinfection of direct dringking water system are: high flash sterilization, which cannot effect the taste of the drinking water, operation and maintanance are easy. UV disinfection has the flash sterilization, meanwhile, pipe dual water supply is different from cans of water, the sterilized water just now may be drunk at once. As a result, in the practical project, UV disinfection can be used to meet the requirements of sterilization, at the same time, it won’t effect the taste of drinking water.

　　(3). Cyclical constant voltage frequency conversion water supply system

　　Direct drinking water supply system uaually adopts the constant voltage frequency conversion to supply water cyclically.

　　III. Features of system:

　　Dual water supply, thorough seperation of drinking water and living water, recoverability of sewage, saving water resource;

　　Built-to-suit, combine with practical engineering, design, choose and customaze the most suitable equipment for you;

　　Physical filtration, use the membrane seperation technology to remove bacteria and virus safely and reserve the beneficial microelements and mineral substances;

　　Instant available, deliver direct drinking water by cyclical disinfection pipe network, offer you purified water which is fresh and instant;

　　Long service life, technology of producing water is mature, which can ensure it in the stable operation in the long-term and the the low costs;

　　Non-attended, PLC auto control which monitor the water quality and breakdown at any time, unnecessary person to monitorit, hunman-computer interface and remote monitoring.

　　Feasibility analysis of pipeline direct drinking water in school

　　Present method of drinking water and existing problems in the school:

　　1.Direct drinking tap water

　　There are many poor area, students drink tap water directly, which is more common in summer. With regard to the majority area, tap water is polluted, whose water resource is polluted, overloading operation and tap water transmission and distribution pipeline are also polluted, as a result, which can effect the bad water quality, indexes of hygiene exceed, especially for the iron rust exceeds in the water, the worse the water quality is, the more chlorine bleach is put into the water, the organic substances in the water and redundant chlorine will produce trichloromethane, which is the strong carcinogen. We emphasize that tap water is living drinking water, not drinking water. As the water resource of tap water, pollution level is not going well, so we don't recommend to drink tap water except the raw water is protected well in the big city, the purification condition of water plant is advanced, the terminal water quality is guaranteed. Nationalwide, due to the purification technology of water plant, equipment and management, tap water quality and water delivery pipe we cannot meet the level of foreign countries whose tap water can be drunk directly.

　　2. Drinking hot water

　　Because of the secondary pollution and odor problems in tap water, to ensure the students drink healthy water, there are some coolective boilers and water heaters in the schools to boild the water for drinking. Make the problem water boiled, but the boiled water just kills the microorganism in the water, the heavy metal, organic substances and so on are still kept in the original tap water. So the school needs the further treatment, then make it boiled, that is better for students to drink hot water or drink water directly.

　　3. Students themselves bring water

　　It is quite common for students to bring water, and there are various drinks, they are purified water, distilled water, coca cola and beverage with different brands and containers. This phenomenon is the trouble for parents and students, one more task for them to bring water when they are leaving home, in additional, which will effect the cleaning of classroom and the desks, at same time produce the one-upmanship between students.

　　4. Drinking from canteen

　　For students whose family are rich, they feel “bring water” is a trouble, so their parents would give them pocket money to buy beverage. The majority money they use to buy coca cola, ice-cream and so on, something like that, just for “Jie chan”. This way of spending money will cause the bad habit of wasting. And more students may spend the money in playing, which also cause the one-upmanship phenomenon.

　　5.Cans of drinking water

　　There are so many schools to introduce the intelligent card drinkingwater machine, getting water by using card, it is uncertain that one cup is 0.01~0.05 yuan, but the intelligent card is not intelligent, the price of water is high, which causes the secondary pollution, water quality can not be controlled, the trouble of water delivery and IC card management have made the water machine out of service.
