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.

Category Introduction

Ultra Low Pressure Ro Membrane For Commercial is a reverse osmosis membrane product designed specifically for commercial applications. It is suitable for water sources with a salt content not exceeding 2000 mg/L, including surface water, groundwater, and municipal water supply, and can efficiently desalinate. This product has ultra-low pressure operation characteristics, which can reduce energy consumption and improve water purification efficiency. It is mainly used in small water purification scenarios, such as automatic water vending machines in residential areas or parks, direct drinking water equipment in office buildings, and pure water preparation systems in medical laboratories. Ultra Low Pressure Ro Membrane For Commercial provides a reliable water purification solution for the commercial sector through its stable desalination performance and wide adaptability.
