Pre-purifier role _ Jinfeng Yu Lu (certified) _ Shenzhen purifier provided by Shenzhen good feng shui Technology Limited. Shenzhen good feng shui Technology Co. (www.jfyl.net) Guangdong Shenzhen, water purifier leaders, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In good feng shui technological leadership with the staff warmly welcome all inquiries negotiations to create good feng shui Technology a better future. Insiders view: water purifier market opportunities brought about water pollution from three years ago, Qujing "illegal dumping of chromium slag" event to the previous year's Guangxi cadmium pollution incidents; drift dead pig on the Huangpu River from Shanghai last year to this year in April Lanzhou Water benzene exceeded, the Han River Water Quality Wuhan excessive ammonia influence, and again water pollution, so the city off guard, people worrying. June 2014 issued by the authority of "2013 China Environmental Status" shows that 74 cities across the country focus on monitoring only 15% of water is healthy. Long water industry expert consultants Gu Chuan said water pollution incident to household water purifiers attention, drinking water, health knowledge are becoming more common.

Reverse osmosis systems include high-pressure pump, reverse osmosis membranes, membrane housing, cleaning systems and associated piping, valves, measuring instruments. Reverse osmosis membranes used by the US Dow produced 4040RO BW30-365 Dow membrane, desalination rate level in more than 98%, reverse osmosis water conductivity less than 20μS / cm. Reverse osmosis membrane element consists of three layers of thin film composite, the surface layer of poly aromatic amines milling material, thickness of about 2,000 angstroms central role of water purifier, layer by layer of microporous polysulfone support, can withstand high pressure, the mechanical tension and with good resistance to chemical attack, the component has a larger membrane area of ??370 square feet of water purifier, a relatively large capacity water flux. Pressure membrane tube selection 4040-2 stainless steel membrane shell, the pressure membrane shell is 304 stainless steel with anti-corrosive, pressure 300psi (2.1MPa), pipe wall is smooth and easy handling characteristics. Hangzhou Nanfang stainless steel high-pressure pump with vertical high-pressure pump, model CDL4-16, flow of 3m3 / h role in household water purifiers, lift 160m, power is 3KW. The pump is a stainless steel structure, water purifier without refueling and maintenance role, with small size, high efficiency, low noise characteristics.
