The RO B400 LE is a spiral-wound composite polyamide membrane element that provides higher permeate flux than standard membrane elements. Its main feature is that it requires lower feed water pressure than HR, HF and FR series membrane elements, hence the designation LE (Low Energy). This type of membrane element is specifically designed for industrial and drinking water treatment projects, such as brackish water or low-salinity water sources.
