4" x 21" Extra Low Pressure RO Membrane (1,000 GPD)
Proudly manufactured in the United States by Hydrocomponents & Technologies Inc. (HCTI), this is an industrial-grade, extra low pressure (XLP) reverse osmosis membrane engineered for high-performance commercial water treatment applications. Designed to fit standard 4-inch by 21-inch pressure vessels, this element utilizes advanced thin-film composite technology to provide superior filtration efficiency. By operating effectively at a reduced feed pressure of just 100 PSI, this HCTI membrane minimizes the energy consumption of high-pressure booster pumps while maximizing system throughput, making it a highly cost-effective solution for reducing overall facility operating expenses.
This American-made element is built for consistency and durability, delivering a nominal permeate flow rate of 1,000 gallons per day (GPD). With a stabilized salt rejection rate of 99.00%, it provides robust removal of total dissolved solids (TDS) and other common contaminants, ensuring reliable water quality for commercial RO setups. Whether used in small-scale commercial purification or as part of a multi-stage industrial system, this membrane is designed to maintain consistent output even under variable feed water conditions, offering a dependable balance of high flux and stringent, energy-efficient purification.
