Brief Introduction:
The 1812-sized and 2012-sized residential membrane elements are mainly applicable to various small-sized systems, such as household water purifier and other water purifying devices in hospital and laboratory.
Being suitable for the desalting treatment of those water sources with salt concentration lower than 2000 ppm, such as surface water, underground water, tap water and municipal water, etc., ULP series are mainly applicable to numerous applications of various sizes, such as pure water, boiler water replenishment, foodstuff processing, and pharmaceutical production, etc.
