Purified Water Equipment

Purified Water Equipment Purified water equipment is used to produce pure water to meet the needs of various industries, commonly applied in the chemical and pharmaceutical sectors. The entire system of purified water equipment is constructed entirely from stainless steel materials, and a sterilization device must be installed before the point of use. Utilizing advanced processes such as reverse osmosis and EDI, it is specifically designed to create complete sets of high-purity water treatment processes to meet the water requirements for purified water production and large-volume infusion preparation in pharmaceutical factories. Main Functions of Purified Water Equipment Multi-Media Filter Multi-media filter tanks are typically filled with filter materials such as quartz sand, anthracite, and manganese sand. Their primary function is to reduce water turbidity and remove a large number of bacteria, viruses, and organic matter from the water, thereby creating favorable conditions for subsequent disinfection processes. Manganese sand is particularly effective in removing iron and manganese. Activated Carbon Filter Tank Activated carbon possesses a large number of micropores and an enormous specific surface area, giving it strong physical adsorption capabilities. It is highly effective in adsorbing impurities in water, especially organic matter and microorganisms. The oxygen-containing catalytic oxidation and chemical adsorption functions formed on the surface of activated carbon can remove certain metal ions from the water. Activated carbon also adsorbs residual chlorine in the water, protecting downstream stainless steel equipment and pipeline surfaces while meeting the inlet water requirements of subsequent water treatment units. Automatic Backwash and Regeneration Softening Tank The softening tank is filled with sodium-type cation exchange resin. Through ion exchange reactions, the resin reduces water hardness, preventing calcium and magnesium ions from combining with carbonate and sulfate ions to form scale in subsequent water treatment equipment or pipelines. Precision Filter The precision filter, also known as a safety filter, typically has a filtration accuracy of 5μm. Its role is to intercept all substances with a particle size larger than 5μm to meet the inlet water requirements of the reverse osmosis system. Reverse Osmosis The key to reverse osmosis technology lies in the performance of the reverse osmosis membrane, which is responsible for desalination. The reverse osmosis membrane is a semi-permeable membrane that allows only water molecules to pass through while blocking solutes. In addition to the principles of reverse osmosis and osmosis, reverse osmosis technology also utilizes the membrane's selective adsorption and sieving mechanisms for organic matter. The pore size of reverse osmosis membranes is mostly less than or equal to 10×10⁻¹⁰m, and its separation targets include ions in solutions and organic matter with molecular weights of around several hundred.
