According to the different USES of domestic water, tap water entering households is divided into domestic water and drinking water. Conventional household water purification solutions use ultrafilter + pure water machine as the main water production tool, and then obtain water purification through direct drinking machine, pipeline machine, water softener and other water purification terminal equipment. The overall water purification solution is expensive and wasteful. In view of this situation, longwei water purification creatively put forward the concept of dual-mode separated water supply, using a dual-water purifier as the main water production equipment, to meet the needs of household water through the separated water supply, economic and environmental protection.

Dual mode mass water supply purifier

With a dual-mode design, namely UF membrane +RO membrane design, lonwe ro-189a can connect different water pipes according to different water requirements.

UF filtration: this filter can be used to remove colloids, suspended substances, bacteria, viruses, macromolecules and organic compounds, etc. The filtered water can be used for washing face, bath, vegetables, fruits, clothes, etc.

RO membrane filter: remove the organic matter in water, heavy metal ions, bacteria, virus, heat source and other impurities, the filtered water is almost pure water, achieve the goal of healthy drinking water, can be used for cooking, soup, cook, etc., can also with terminal equipment such as pipeline machine, straight drink machine family platform of drinking water, drinking water health anytime and anywhere!

Long Wei campus special water system with the application of heat exchange technique, make out of the water through the heat exchanger when releasing energy and cooling into the warm boiling water, let come in cold water before entering the water boiler attract heat preheating to near boiling water temperature, which greatly limits the electricity needed to save the water to boil, completely changed the traditional water boiler time-consuming, the shortcomings of power consumption, and to ensure that the water temperature is suitable for students.

Principle of energy saving of special drinking water system in longwei campus

After the 20℃ water is absorbed by the heat energy released by the boiling water through the exchanger, it reaches 85℃ before entering the boiling water boiler. From 85℃ to 100℃, only 15℃ need to be increased. However, if the tap water is heated from 20℃ to 100℃ by an ordinary water heater or drinking machine, the energy saving rate of the water heater is :(80-15) ÷80=81.25% compared with that of the ordinary water heater or drinking machine
