Reverse Osmosis (RO)

Reverse osmosis is a process that industry uses to clean water, whether for industrial process applications or to convert brackish water, to clean up wastewater or to recover salts from industrial processes.

In reverse osmosis process cellophane-like membranes separate purified water from contaminated water. RO is when a pressure is applied to the concentrated side of the membrane forcing purified water into the dilute side, the rejected impurities from the concentrated side being washed away in the reject water. RO can also act as an ultra-filter removing particles such as some micro-organisms that may be too large to pass through the pores of the membrane.

Common membrane materials include polyamide thin film composites (TFC), cellulose acetate (CA) and cellulose triacetate (CTA) with the membrane material being spiral wound around a tube, or hollow fibres bundled together. TFC spiral wound membranes are most used due to its superior strength and durability, higher rejection rates and are more resistant to microbial attack, high pH and high TDS.

We can offer ready to use RO skid for water treatment and tertiary filtration of secondary treated wastewater for its recovery and reuse.

We have successfully installed wastewater treatment plants inclusive of reverse osmosis process for water recovery for chemical, oil and pharma formulation industries.
