Ultra-Low-Pressure Reverse Osmosis ULP Series Membrane Elements
Detailed description
(1) Product Positioning
ULP-series membrane elements are suitable for desalination applications using municipal tap water or groundwater as the feedwater source, under low-salinity conditions (TDS < 1000 mg/L). They are primarily employed in large-scale residential water supply systems, purified water production, and the preparation of industrial-grade pure water for food and beverage industries, among many other fields.
(2) Product Features
It can achieve a high water flux under extremely low operating pressures while maintaining a high desalination rate, with an operating pressure approximately 30–50% lower than that of conventional brackish‑water membranes and an energy consumption reduction of more than 20%.
(3) Product Performance
