  • Applying Oxidation Reduction Potential Sensors In Biological Nutrient Removal Systems
    Products Aclara Jacobi Carbons Endress Hauser Inc KROHNE Inc Kaeser Compressors Inc Emerson Process Management Rosemount Analytical Degremont Technologies Brentwood Industries View All Providers Application Note February 3 2012 Applying Oxidation Reduction Potential Sensors In Biological Nutrient Removal Systems Source Hach Company By Bob Dabkowski Hach Wastewater Specialist Oxidation Reduction Potential ORP is commonly a misunderstood science Applying ORP to wastewater treatment is often a considered a mystery and sometimes called black magic It is easy to overlook this simple sensor and the complex data it brings to the wastewater treatment professional The following application note details the theory of ORP a background into common biological nutrient removal BNR systems and the basic application of ORP sensors into these common BNR systems Unlike dissolved oxygen control in aeration basins ORP control in BNR systems focuses on optimization of the process and not necessarily cost savings although some cost savings may be realized Oxidation Reduction Potential theory is best summarized as an indication of the solution s ability to oxidize or reduce another solution It can also be defined as the sum of all the potentials in the water Every ion compound and element in water exhibits a potential the sum of these potentials is the ORP value of the water The ORP value of the water tells the treatment professional if the environment of the water is oxidative positive millivolt values or reductive negative millivolt values A simple way to think of ORP is through dechlorination Chlorine is a strong oxidant adding chlorine to the water changes the ORP to a positive value indicating an oxidative solution The chlorinated solution oxidizes organics and also kills microorganisms Since this strongly oxidative solution would be harmful to the environment it needs to be neutralized by adding a strong reductant such as sodium
