Ultra-low Pressure RO Membrane Elements ULP-4021

ULP-4021 is an ultra-low-pressure reverse osmosis membrane independently developed by BANGTEC, specialized in desalination treatment for water sources like surface water, groundwater, and municipal water, with a recommended salt content threshold below 2000mg/L, ensuring stable performance in such low-salinity environments. It is widely applicable to small-scale water treatment systems: from automatic water vending machines in residential areas or parks, to direct drinking equipment in office buildings, and even pure water systems for medical laboratories, perfectly matching the compact, efficient needs of these scenarios.​

Its standout advantage lies in ultra-low operating pressure—only about 2/3 of conventional low-pressure composite membranes—paired with impressive core performance: 99.3% desalination rate and 1000GPD water production. This low-pressure design directly cuts costs: it reduces investment in supporting equipment (such as pumps, pipelines, and containers) and lowers the long-term operating costs of reverse osmosis systems, ultimately boosting the economic efficiency of water treatment projects.
