Category Introduction
The Domestic RO Membrane 3013 is a reverse osmosis filter element widely used in both residential and commercial applications. Its core function is to effectively remove dissolved salts, heavy metals, bacteria, and other impurities from water through high-precision filtration to a resolution of 0.0001 micron, achieving a salt rejection rate of up to 98%, thereby producing clean and safe drinking water.
This membrane element measures 3 inches by 13 inches (approximately 76 mm by 330 mm) and is compatible with a variety of standardized membrane housings. Available in various water output capacities, ranging from 150 GPD to 800 GPD, it meets the water needs of diverse applications, from ordinary households to restaurants and hotels. Utilizing a polyamide film composite material, it typically operates within a pH range of 2-11, providing a highly efficient filtration solution for domestic reverse osmosis water purification systems.
