METHOD OF DETERMINING THE CONCENTRATION OF PATHOGENS OR OXIDIZABLE ORGANIC COMPOUNDS USING AN OZONE TITRATION SENSOR

摘要

The invention describes a method of ozone titration sensing which utilizes an ozone addition to a target solution, detection of ozone using an Oxidation-Reduction Potential (ORP) electrode or an Ultraviolet (UV) absorption photodiode or other means to detect ozone and the determination of the relative concentration of organics or pathogens subject to ozone oxidation which are present in the target solution. The inventive sensing method can be usefully employed to determine the relative concentration of pathogens such as viruses, bacteria and/or parasites that are readily oxidizable by ozone in aqueous solutions. The inventive sensing method may be used to control an ozone (or other oxidizing or disinfecting) compound dispensing system to optimize the dosage of ozone (or other disinfecting compound) necessary to produce a desired kill ratio or to generate a desired residual of ozone concentration in an aqueous solution after pathogen disinfection.

1. A method of determining the concentration of oxidizable organic compounds and/or pathogens in solution comprising the steps of:
a) generating a prescribed quantity of ozone using an ozone generating system; b) delivering a prescribed quantity of ozone from the ozone generating system to a target solution containing oxidizable organic compounds and/or pathogens; c) measuring the quantity of ozone remaining in the target solution after a prescribed time duration with an ozone measurement system; d) calculating the quantity of ozone remaining after reaction in the target solution, wherein the quantity of ozone remaining in solution after the prescribed time duration is a function of the amount of ozone added to the target solution and the amount of ozone that has reacted with the oxidizable organic compounds and/or pathogens.
