The World is Thirsty for RO-Treated Brackish Water

The greatest thing about reverse osmosis is that you can apply the technology to all types of water and get different results. Many use the technology to thoroughly filter impurities out of water, but if you feed a reverse osmosis system with cleaner water to begin with, your end product will end up being of higher quality. Adding an RO filter for brackish water in your system can increase quality and output.

Greenhouse and hydroponic farmers have caught on to reverse osmosis to purify their irrigation water for agricultural use. One particular farmer in Florida uses a 300 liter/day reverse osmosis system which produces water with less than 15mg/1l of sodium. Upon switching to a brackish water RO system, the farmer’s production of European cucumbers in a twenty two acre greenhouse went from 48,000 cucumbers/day to 84,000 cucumbers/day. This is virtually double the output, which was achieved by the relatively simple shift from contaminated surface water canal sources to low-salinity brackish groundwater.

The product of brackish water RO has lower levels of bacteria and nematodes, thus helping avoid plant diseases. Also, an RO membrane intended for brackish water typically has a cellulosic membrane, which is resistant to chlorine. Furthermore, a brackish water filter can also be added to a previously existing RO system, which helps take stress off the first system and resulting in a more efficient workflow with better results.

  1. The filter paper lets the water through, but not the sand. The sand is trapped in the filter paper. Clean water comes out of the bottom of the funnel. water purifier
