Description

The ULP22-8040 reverse osmosis membrane is a premium ultra-low pressure 8-inch industrial thin-film composite (TFC) membrane designed to deliver high water production with excellent salt rejection while operating at significantly lower pressures than conventional RO membranes. Its advanced membrane technology reduces energy consumption, lowers operating costs, and extends the service life of pumps and associated equipment.

Designed for treating municipal water, borehole water, surface water, and other low-salinity water sources with total dissolved solids (TDS) levels up to 2,000 ppm, the ULP22-8040 is ideal for commercial and industrial water treatment applications. It produces high-quality purified water for bottled water plants, food and beverage processing, pharmaceutical manufacturing, boiler feed water, and other industrial processes where consistent water quality is essential.
