Remove Na from wastewater for irrigation




Dear Sir I want to use water from a sewage treatment works for irrigation purposes on pastures. I need to remove half of the Na which is at 7 me/l at present, as cheaply as possible.

Hi, Robert

I think reverse osmosis is the only practical system for removing sodium from a high volume of wastewater. Good luck with it.
