Reverse Osmosis (RO) is a pressure-driven membrane separation technology used for removal of dissolved salts (TDS), hardness, heavy metals and dissolved organic impurities from water.
RO membranes function as a molecular barrier, allowing only water molecules to pass through while rejecting contaminants, producing high-quality permeate suitable for industrial and reuse applications.
RO systems are widely adopted where consistent, low-TDS water quality is required, including water recycling, industrial process water and high-quality utility or wash water applications. A properly engineered RO system relies heavily on effective pretreatment and precise operating control to prevent fouling, scaling and membrane degradation.
Applications of RO Systems
Water recycling and reuse systems
Industrial process and utility water treatment
High-quality wash water applications
RO-based ZLD and high-recovery treatment systems
How S N Group of Environment Delivers RO Systems
At S N Group of Environment, RO systems are engineered as complete integrated treatment solutions rather than standalone membrane skids.
Our design philosophy emphasizes long membrane life, stable operation and optimized recovery with minimum operating cost.
