Abstract:
1. A method to purify water, comprising: (a) holding and storing unpurified water in a septic tank having an outlet to provide a water stream for processing; (b) processing the water stream in an electrocoagulation and flocculation reactor that uses electrical energy to convert at least some of the dissolved solid material present in the water stream into suspended particulate form that can be subsequently filtered and separated out; (c) introducing air into the water stream to promote aerobic processing of contaminants in the water and to assist in agglomeration and flocculation of any suspended solid material present in the water; (d) filtering the water stream to separate suspended solid material from the stream and to adsorb some of its dissolved contaminants; (e) processing the water stream with a reverse osmosis processor, the reverse osmosis processor providing a reject stream that provides water back to the septic tank and a recycle stream that provides unpurified water back to the water stream exiting the septic tank; (f) determining a resistance to manage a highest conductivity and lowest resistance of the reject stream; and (g) applying a voltage to set an electric current applied to the reject stream in the electrocoagulation and flocculation reactor to lower a concentration of dissolved solid materials having entered the septic tank.
