Wastewater treatment plants are common over the world. Within the wastewater treatment process, it is important the measure the COD (Chemical Oxygen Demand) value, i.e. the amount of oxygen necessary to break down organic materials. The Rhosonics Model 9585 COD Meter can be used to measure the COD of brewery wastewater streams.
Fluctuating loads will upset your treatment plant and will lead to bad treatment and can cause foaming. Measuring the COD using a high quality Model 9585 COD Meter can help you check your treatment plant by means of feed forward control of the air compressors and increasing the return activated sludge (RAS). COD can also be toxic for bacteria above a certain concentration: inhibition of bacteria will lead to poor wastewater treatment or can upset the treatment completely.
