Chen purifier on Granville Granville Chen core technology advantages purifier technology advantages of using five reverse osmosis filtration system automatically and intelligently, effectively remove heavy metals and other harmful substances, ensuring the safety of drinking water quality. Shanghai Wei Chen purifier reflect technological advantages: a. 95% of the parts are machine independent research and production, the production process up to 110 multi-channel processes, 1-5 micron pp cotton uses a unique spray melt process to ensure accurate filtering accuracy. II. Granular Activated Carbon: The water purification industry best activated carbon, each batch of raw materials have been a number of detection granularity, ph value and so on. Three. Core reverse osmosis membrane: imported reverse osmosis membrane, the exclusive use roll film technology, quality stable and durable, the implementation of strict production standards in film processing, film processing plant closed a professional production and processing areas clean, constant temperature and humidity , from the diaphragm to the finished film, every process has a detailed production standards and strict implementation of the production process of the film using a dedicated automatic slitting machine, automatic gluing, maintaining product quality and stability of the film. Four. Must go through as many as 210 technical reliability test, 100,000 times life test each product before the factory to ensure safe and efficient products. Shanghai Wei Chen all processes of production of water purifiers are rigorously checks its core technology has always synch with today's top water treatment technology.
