Product Overview

Description


LP Series:Low Pressure RO Element


 


Brief Introduction


LP series(low pressure) aromatic polyamide  RO element is developed by VONTRON for treatment of brackish water .It has the characteristics of low-pressure in operation, high permeate flow and excellent rejection performance in removing of solvable salts, TOC ,SiO2,etc.It is especially suitable for the preparation of high purity water in electronics and power industry.


 


Scope of Application


LP series is normally suitable for treatment of brackish water,surface water, underground water and municipal water with TDS is less than 10000 ppm.It is mainly used for producing various scales of bottle water, drinking water,industrial used pure water,high purity water, boiler replenishment water, also for Waste water recycling ,material concentration,purification and refining purposes.
