The 4040 reverse osmosis membrane is a core filtration component of water treatment reverse osmosis systems. It is compatible with various water treatment equipment, offering stable operation, excellent filtration performance, and a continuous output of high-quality purified water. It is the preferred filtration consumable for industrial water purification, wastewater treatment, and mining applications.
This 4040 membrane uses high-quality Dow membrane material, offering extremely high filtration precision. It effectively removes various impurities from the water, thoroughly filtering out dissolved salts, heavy metals, bacteria, microorganisms, viruses, and other harmful substances, comprehensively purifying water quality and ensuring water cleanliness from the source.
In terms of core performance, this membrane element boasts superior desalination capabilities, achieving a desalination rate of up to 99.7%, a leading performance in the industry. The product employs an advanced three-layer membrane structure design, effectively improving the purified water recovery rate, achieving a product water recovery rate of up to 60%. During operation, the TDS value remains stable, exhibiting strong anti-interference capabilities and easily adapting to various complex water source environments, demonstrating exceptional adaptability and practicality. Meanwhile, the membrane housing features a dedicated waterproof hammer impact structure at both ends, effectively buffering water pressure shocks, preventing damage to the membrane elements, and significantly extending their service life. It supports multiple units connected in series, flexibly increasing the overall water production capacity to meet different scales of water demand.

With its stable and reliable filtration performance, the 4040 reverse osmosis membrane has a wide range of applications. In mining water treatment, it effectively removes harmful impurities, ensuring the safety of production and domestic water in mining areas. In wastewater treatment, it deeply purifies wastewater, helping it meet compliant discharge standards. In various industrial production filtration scenarios, it provides high-purity production water to production lines, effectively ensuring stable production processes and improving overall production efficiency.
