System and method for controlling the generation of a biocidal liquid

A system for generating a biocidal solution having a predetermined level of available free chlorine and pH, the system comprising:

• an electrolytic cell that generates the biocidal solution having the predetermined level of available free chlorine and pH by an electrolytic reaction, the electrolytic cell comprising an input pipe for receiving an input brine solution, an anode chamber including an anode and a cathode chamber including a cathode separated by a separator, and electrical connections for application of voltage to the anode and cathode;
• temperature sensing means for detecting a temperature of a solution of the electrolytic cell and outputting a signal indicative of the detected temperature;
• and
• process control means for adjusting the voltage applied to the electrolytic cell thereby maintaining the level of available free chlorine and pH at the predetermined level in response to the signal output from the temperature sensing means.

A system for controlling an electrolytic cell that generates a biocidal solution having a desired pH range and a desired available free chlorine range from an input solution, comprising:

• an electrolytic cell that receives the input solution and has electrodes for receiving an applied voltage, wherein current is passed from a first electrode to a second electrode through a solution in the electrolytic cell;
• a temperature detector that detects a temperature of a solution and outputs a signal indicating the detected temperature;
• and
• a processor that controls a voltage source to apply an amount of voltage to the electrolytic cell in response to the signal output from the temperature detector.
