Abstract:
1. A method of controlling the amount of chlorine source present in an aqueous stream, comprising the steps of: (a) providing a chlorine concentrate tank having therein a source of chlorine; (b) providing a first aqueous stream; (c) dividing said first aqueous stream into a second and a third aqueous stream; (d) introducing said second aqueous stream into said chlorine concentrate tank and into contact with said chlorine source; (e) introducing said third aqueous stream into a bypass line; (f) removing a fourth aqueous stream from said concentrate tank containing said chlorine source; (g) combining said third aqueous stream from said bypass line with said fourth aqueous stream from said concentrate tank to form a fifth aqueous stream; (h) introducing said fifth aqueous stream into a detention tank wherein said chlorine source is allowed to sufficiently react with said aqueous stream; (i) and removing a sixth aqueous stream from said detention tank wherein said sixth aqueous stream has a free chlorine content of from 0.3 to 2.0 ppm; wherein said method operates strictly from the pressure generated from the action of a hand pump and requires no electricity.
