Adopts advanced 4040 RO membrane technology, which is capable of removing up to 99.7% of inorganic salts and heavy metal ions, and effectively eliminating colloids, microbiological organic materials, bacteria, protozoa, pathogens, and various inorganic chemical substances. The system features a chemical-free operation, ensuring stable production of high-quality pure water with zero pollution discharge and significantly reduced production costs. It is equipped with a comprehensive pretreatment system, including an activated carbon adsorption filter and precision quartz sand filter, to ensure optimal feed water quality. Constructed with durable 304 stainless steel framework and high-quality pipe fittings, the system provides superior corrosion resistance and long-term reliability. It is also integrated with an automatic pressure protection system and online monitoring instruments to ensure safe and stable operation. The RO membrane can be cleaned through both automatic and manual modes. The chemical cleaning process employs either citric acid or sodium hydroxide solutions, providing effective removal of fouling and scaling to maintain membrane performance. With its long service life, user-friendly operation, and strong adaptability, this system is suitable for a wide range of applications in industrial, commercial and laboratory settings.
