Abstract

PURPOSE:To prevent lowering of performance of modules and to extend the life time of the modules, by pressurizing raw liq., which passes through a reverse osmotic unit having two or more reverse osmotic membrane modules, in order along the direction of the flow step by step by use of pressurizing pumps installed within the unit.
