Can the Waste Be Used?
a) First thing: test the TDS in the waste-water stream. If the TDS is below 1,000, you can use the water in your plants. b) Alternately, mix some of that water with tap water to mop the house. Make sure you dilute it with tap water because if the TDS is high and you use just the RO waste to mop the floor, you may see some salt deposition after the water dries. c) You can use the waste water to clean the sewage pipe at home or kitchen because of its saline nature. d) You can use it to flush toilets. Taste and Odour Taste and odour of output water should be acceptable; in other words, there should not be any bad odour or taste.
