RO PLANT

This short paper looks at the use of reverse osmosis (RO) in process water treatment applications and considers the process itself, the use of reverse osmosis membranes, and factors affecting water quality and plant performance.
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.
Reverse osmosis will not remove all contaminants from water as dissolved gases such as dissolved oxygen and carbon dioxide not being removed. But reverse osmosis can be very effective at removing other products such as trihalomethanes (THM's), some pesticides, solvents and other volatile organic compounds (VOC's).

The reverse osmosis process

In the 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.
