Reverse Osmosis (RO)

Explore optimized water purification through advanced Reverse Osmosis (RO) technology. Discover how tailored multi-stage RO systems maximize water recovery and ensure top-quality permeate.


Reverse Osmosis (RO) technology represents a revolutionary approach to water purification, especially in Minimum or Zero Liquid Discharge projects, harnessing the natural process of osmosis in reverse to effectively remove contaminants and impurities from water/wastewater. RO technology purifies water by applying hydraulic pressure in excess to the osmotic pressure of brine to a semi-permeable membrane, allowing water molecules to pass through while trapping contaminants, resulting in purified water on one side and concentrated brine on the other. 

Advent Envirocare, a pioneer in water treatment solutions, has been at the forefront of designing high-recovery multi-stage RO systems since 2002. With a wealth of experience and pre-treatment expertise, Advent Envirocare excels in identifying the right membrane provider and membrane configuration to ensure optimal performance. By focusing on factors such as flux, hydraulics, energy efficiency, fouling, scaling and permeate quality, Advent Envirocare customizes RO systems to maximize water recovery. 

In addition to standard RO systems, Advent Envirocare specializes in designing inter-stage hardness removal systems to address specific water chemistry challenges, allowing for high recoveries without compromising permeate quality. Moreover, for applications requiring impeccable permeate quality, Advent Envirocare offers second-pass RO systems, ensuring the highest level of purity and reliability in water treatment solutions.
