LP Series Low Pressure Reverse Osmosis Membrane Elements for Brackish Water

Description

LP Series Low Pressure Reverse Osmosis Membrane Elements are an aromatic polyamide composite membrane element developed by Hongtek for brackish water. The RO membrane elements have the characteristics of low pressure operation, high water production and good desalination performance. The reverse osmosis membranes are suitable for brackish water, tap water, ground water, surface water filtration and other water sources with a salt content of less than 10,000ppm. The 4040/8040 RO membrane replacement elements are universal RO membrane sizes, which can be directly installed in the RO membrane shell, high filtration efficiency and long working life to help end users save cost.

Structure Diagram of RO Membrane Element

Structure-of-RO-Membrane-Element.jpg

● Reverse osmosis, is a membrane separation method that uses pressure difference as the driving force to separate the solvent from the solution.

● Apply pressure to the feed liquid on one side of the reverse osmosis membrane. When the pressure exceeds its osmotic pressure, the solvent will reverse osmosis against the direction of natural osmosis.

● The low pressure side of the reverse osmosis membrane obtains the permeated solvent, namely the permeate, and the high pressure side obtains the concentrated solution, namely the concentrate.
