Pure Water Testing
Pure water refers to water without impurities, referred to as clean water or pure water, is pure, clean, does not contain impurities or bacteria water, such as organic pollutants, inorganic salts, any additives and all kinds of impurities, is to meet the health standards of drinking water for the original water. It is made by electrodialysis, ion exchanger, reverse osmosis, distillation and other appropriate processing methods, sealed in a container, and does not contain any additives, colorless and transparent, and can be directly consumed. Space water sold in the market, distilled water are pure water.
Testing Services
BOC Sciences water quality testing laboratory has CMA, CNAS qualification, with a professional pure water testing team, has been committed to the testing and evaluation of drinking water health, in strict accordance with the standard establishment system, in the field of water quality testing has many years of technical accumulation. We provide testing and evaluation services for products such as drinking water, pure water, mineral water and water-related products contacted by drinking water treatment agents, descaling agents and chemical substances. Pure water treatment process often includes one or several of the following processes: reverse osmosis, ultrafiltration, ion exchange or UV sterilization, etc.. The water quality required varies by industry, but pH control, turbidity monitoring, chlorine testing, conductivity and silicon content testing are always beneficial to improve the efficiency of pure water production.
