ULP/XULP series membrane elements
The series membrane elements are made of polyamide composite membrane material and achieve the required permeation flow rate and high desalination rate under ultra-low pressure operation conditions.
The operating pressure is approximately two-thirds of that of conventional composite membranes. This reduces the investment costs of pumps, pipelines, containers and other equipment, as well as the operating costs of reverse osmosis systems, thereby enhancing economic benefits.
The series of membrane elements are suitable for desalination of water sources with a salinity level of less than approximately 2000 ppm, including surface water, groundwater, tap water and municipal water. They are mainly used in various industries, such as pure water production, boiler feed water, food processing and pharmaceuticals.
