Product Description
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, SiOz, 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 wastewater reuse, material concentration, purification and refining purposes.
