Water quality and Chemical Oxygen Demand

Why measure pH?

pH is a measure of how acidic or alkaline (caustic) the water is. It is defined as the negative log of the hydrogen ion concentration. Water at either end of the scale can have significant consequences. Acidic effluent is known to damage and erode our sewage systems. The food industry can have particularly acidic wastewater, which needs pH balancing. pH is measured using a glass electrode containing an electrolyte solution and a reference electrode. When placed in water, an electrical force produced between the internal solution and the water can be measured. This force is a measure of pH.
