The Shanghai Yetuo Basic Ultra Pure Water Machine, as the core equipment for pure water preparation in laboratories, small testing rooms, and other scenarios, uses a modular purification process to convert ordinary tap water into pure water that meets experimental standards. Its core principle revolves around multi-stage filtration, deep desalination, and fine purification layer by layer promotion. Through the synergistic effect of physical filtration and ion exchange, impurities, ions, colloids, and other pollutants in the water are accurately removed, achieving efficient preparation of pure water. The entire process is automated and can stably produce water without complex operations.

The preparation of pure water for equipment starts from the pretreatment system, which is the fundamental step of pure water preparation. The tap water first enters the PP cotton filter and activated carbon filter. The PP cotton filter physically intercepts large particles such as sediment, rust, and suspended particles in the water with a micron sized filtering aperture, avoiding subsequent blockage of the core filter; Activated carbon filter utilizes its porous structure to adsorb residual chlorine, discoloration, odors, and some organic matter in water, thereby removing the oxidative damage caused by residual chlorine to subsequent resins and membrane components, laying a solid foundation for subsequent purification processes.

The pre treated water enters the core desalination process, which is a key step in removing ions from the water. Basic ultrapure water machines mainly use ion exchange resin column technology. The resin column is filled with a mixture of anion and cation exchange resins. When water flows through the resin, cations and anions such as calcium, magnesium, sodium, and chlorine in the water will undergo displacement reactions with hydrogen ions and hydroxide ions on the resin. Harmful ions in the water are adsorbed by the resin, and the displaced hydrogen ions combine with hydroxide ions to form water molecules, thereby achieving deep removal of ions in the water, greatly reducing the conductivity of water, and initially obtaining pure water.

After desalination, the water will enter the terminal refining and suppression stage. The pure water passing through the resin column will be filtered through high-precision ultrafiltration membranes or microporous filters to remove trace colloids, resin debris, and microorganisms remaining in the water, further improving the purity of the water quality; At the same time, the equipment is equipped with a UV ultraviolet suppression module or a circulating suppression system, which effectively suppresses the growth of fine Jun and mold in the water, avoids secondary pollution, and ensures the stability of the effluent quality.

The various purification units of the Shanghai Yetuo basic ultrapure water machine form a closed-loop connection. From raw water inlet to pure water outlet, the entire process is monitored in real-time by the equipment's built-in water quality sensor. When the filter element reaches saturation, the equipment will promptly remind replacement to ensure that each level of purification process is in the best working condition. The entire process abandons complex operating procedures and can continuously prepare pure water that meets the GB/T 6682 laboratory water standard with just one click. The effluent has stable electrical resistivity and can meet basic water needs such as laboratory glassware cleaning, routine chemical experiments, and instrument lubrication. With the advantages of high cost-effectiveness and high stability, it has become an ideal choice for small-scale water use scenarios.
