Abstract
A process for indicating and regulating the content of chlorine or similar water purifying agent in flowing water or sewage is characterized by the utilization of the potential difference produced between two electrodes, one of which is surrounded by the untreated water and the other by the treated water. The potential difference may be utilized to actuate a galvanometer, the needle of which oscillates between two stops and is in a motor circuit whereby the motor is rotated in one direction or the other to open or close a valve supplying chlorine to the water pipe. The chlorine may be added directly to the sewage or may be dissolved in water before the addition. As shown in the <PICT:0367821/III/1> Figure, the main supply of chlorine is added in constant quantity, the galvanometer serving to regulate the peak requirements of the sewage. The electrodes 18, 21 are contained in glass tubes 17, 20 dipping into a test tank 16. The tube 17 receives untreated water from a pipe 15 and the tube 20 receives treated water through the pipe 19. The overflow is led back to the pipe to a region of low pressure. The chlorine is supplied from a cylinder 13 and the main constant supply is derived from a dosing apparatus 14 and a container 12 through a pipe 11. The galvanometer is in series with a Wheatstone bridge arrangement whereby an adjustable compensating potential may be applied to the galvanometer in order that it may read zero when the electrodes 18, 21 are both surrounded by untreated water. The galvanometer needle 25 actuates through a relay, a valve 26 in an auxiliary water pipe 27 having a choking disc 29 therein. The pressure difference at the sides of the disc is utilized through pipes 28, 32 to actuate a control valve for the chlorine dosing plant 31, 33 in known manner, to regulate the variable peak chlorine requirements of the sewage. The electrodes may be of the same or different materials, gold, platinum, copper, silver, zinc, cobalt, aluminium, carbon and magnetite being suitable. The electrode in the treated water and, if desired, the other electrode preferably consist of a material which lies on the positive side of an electromotive series in which hydrogen equals zero. The Wheatstone bridge compensator may be replaced by electrodes of the same materials as used in the main indicating and regulating circuit. If desired, the chlorinated water previous to being admitted to the tank 16 may be passed over calcium carbonate to neutralize the acidity. The untreated water in the pipe 15 may be similarly treated. The process may be used for indicating and controlling the content of hypochlorite, sodium carbonate, caustic soda, phosphates and aluminium sulphate.
