Reverse osmosis (RO) 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. It 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) ... |
