　　Product name: organ’s school direct drinking water treatment equipment Product model:

　　Product features: reverse osmosis chooses the polymer, selective permeability membrane, it can remove ion from filtrate and organic substances of small range and molecular weight, such as bacteria, viruses, heat source, etc.

　　The details of organ’s school direct drinking water equipment:

　　Pipeline direct drinking water equipment

　　We use the technology of host machine and pipeline to deliver pure water to different water points. The circulating water pump is operating while treating the water in pipeline network circularly, in order to ensure that there is no bacteria in pipe network and the fresh taste of water, in addition, pipeline direct drinking water has several advantages relative to enterprises of burning hot water, the first, it can save the time of drinking to ensure the work efficiency; the second, because the electricity cost of enterprises of burning hot water is higher, then pipeline direct drinking water can save a part of cost.

　　I. Summary

　　Reverse osmosis uses the polymer, selective permeability membrane, which can remove the ion from filtrate and the organic substances of small range and molecular weight, such as bacteria, virus, heat source and so on. It has been widely used on sea water or desalinization of brackish water, electronics, medical pure water, high pure water of electronics, drinking distilled water and so on. The aperture of reverse osmosis membrane is just 0.001μm, which is one six-thousand of coli. RO principle is to separate water and solution with peemeable membrane, water and solution permeate into each other, finally get the balance, produce osmotic pressure between both phases. If the solution phase is higher than osmotic pressure, then the water in solution phase will permeate in opposite direction of water, utilize the reverse osmosis to get desalted water. Raw water under the enough pressure, which will go through the osmotic membrane and become the pure water, the dissolved substances and suspended substances which can’t go through membrane, they will be discharged by sewage outlet. Bett RO device adopts compound membrane, roll type membrane elements. Standard RO system is the group type, including precision filter, high pressure pump, membrane cleaning pump and pressure container, membrane group, flow/pressure/temperature/electric conductivity meter, PLC control panel and internal connection channels, valves and cables. High presure channel is 316 stainless steel, low pressure channel is PVC.

　　II. Equipment performance features:

　　1.the main parts are foreign famous brands, designed by CAD, advanced technology, stable performance, good hydraulic performance.

　　2.pretreatment protection device to protect high pressure pump and reverse osmosis membrane from damage.

　　3.high desalination rate, roll type compund membrane of low operation pressure will improve the system efficiency and reduce operating cost.

　　4. production water and concentrate have the flow meters, to monitor and regulate the quantity of effluent and systematic recovery rate.

　　5. online electric conductivity meter is continuously monitoring the production water quality, it is also equiped with set value and alarm.

　　6.feed water and effluent system pressure meters are monitoring the osmotic pressure differnce, to hint the cleaning time, comprehensive system mornitoring, automatic meter display.

　　7. sensitive high pressure and low pressure switches; which are to ensure system in the normal operation condition, in case some exceptional conditions can break the equipment.

　　8.the advanced membrane protection system will have a timing flush to the surface, reduce the speed of pollution, prlong the service life of membrane.

　　9.systematic desalinization over 95%, desalinization of single membrane can reach to more than 99%, simple operation, standard.

　　pletely according to users’ requirements, have the most reasonable designs.
