Reverse osmosis membrane is a hydrophilic semi-permeable membrane and the main component of membrane separation technology. With a pore size on the order of angstroms and a charged surface, the reverse osmosis membrane effectively filters and removes dissolved salts, colloids, microorganisms, organic compounds, and other substances from water. Our company supplies reverse osmosis membranes from renowned brands such as Dow, Toray, Hydranautics, Synder, and Hyosung, offering a wide range of specifications.

Water pump is a mechanical device used for conveying fluids or increasing fluid pressure. It transfers mechanical energy from the prime mover or external power source to the liquid, thus increasing its energy. Water pumps are primarily used for the transportation of liquids including water, oil, acidic or alkaline solutions, emulsions, suspensions, and liquid metals.

PP filter cartridge, also known as PP melt-blown filter cartridge, is made of polypropylene ultrafine fibers through thermal melt-bonding. The fibers randomly form a three-dimensional micro-porous structure, with varying pore sizes distributed along the flow direction, enabling surface, deep, and fine filtration in one cartridge. It can effectively capture impurities of different particle sizes. The filtration accuracy ranges from 0.5 to 100μm, and its flux is more than 1.5 times that of comparable filter cartridges with the same accuracy. Different models of end caps can be configured to meet various engineering installation requirements.

Fiberglass tank is a non-metallic composite tank made of resin and fiberglass, produced through computer-controlled machine winding. It possesses advantages such as corrosion resistance, high strength, long service life, flexible design, and strong processability.
