We are the Leading Purified Water Storage and Distribution System, Ultrapure Water Purification System, and RO Water System for Pharmaceutical Industry. The most common filtration technique is reverse osmosis, which is typically used in pharmaceutical water systems. This method is used to remove particles from the water, including particulates. The RO system has a semi-permeable layer that allows water to pass through while rejecting impurities. Reverse osmosis is capable of removing pathogens as well as salts, carbohydrates, proteins, pigments, and other particles with atomic weights more than 250 daltons.
