Reverse Osmosis Membrane Elements RO-3213-1000

Reverse Osmosis Membrane Elements RO-3213-1000 solves the key demand for higher flow in 3213-based systems through innovative design: by reducing the thickness of non-core materials, it frees up space for enhanced water flow, ultimately delivering up to 1000GPD—perfectly meeting owners’ pursuit of efficient water supply.​

Crucially, this flow boost doesn’t compromise purification: it maintains a stable desalination rate, ensuring every drop of treated water meets quality standards. And as a membrane specially engineered for 3213 membrane shells, it fits seamlessly without any custom tweaks, making it a top pick for high-demand small-to-medium commercial scenarios—such as 24/7 community water vending stations or large office buildings with dense users—where both 3213 shell compatibility and continuous high-volume clean water are essential.

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.
