Category Introduction
The Domestic RO Membrane 3213 is a reverse osmosis membrane element designed specifically for home water purification systems. Its core function is to utilize efficient reverse osmosis technology to effectively remove impurities such as dissolved solids, bacteria, viruses, heavy metals, and pesticides from water, thereby producing clean and safe drinking water. This series of membrane elements boasts a remarkable high flux, with water production capacities ranging from 600 GPD (gallons per day), 800 GPD, and even 1000 GPD. These membrane elements meet daily household water needs and provide a stable and reliable water purification solution.
The Domestic RO Membrane 3213 is constructed from a polyamide film composite material, ensuring high filtration efficiency and durability. Under standard testing conditions (25°C, 100 psi, 500 ppm NaCl), this series of membrane elements demonstrates excellent and stable salt rejection, typically reaching approximately 96%. To maintain optimal performance, it is recommended that the Domestic RO Membrane 3213 be replaced every six months to one year, depending on actual water quality and usage, to ensure the purity and health of your drinking water.
