Hello Ghazali, Considering the water source coming from a river, the discharged concentrate could be placed in a lined pit and allowed to evaporate. You of course would need to calculate the total daily discharge from the RO, approximate evaporation, and the size of the pit required. Also it would be advisable to have a second lined pit below the first as an overflow retention pond. This is done here in the US. for Mining Clean-Up Sites where the waste water is toxic with Heavy Metals and Arsenic. Good Luck!
