On the correlation between Turbidity, Conductivity and COD

Introduction COD is one of the most important parameters for wastewater quality. Measuring COD is an expensive and time consuming process. There is a need for an inexpensive, accurate, reliable and continuous technique to monitor COD. Turbidity can be used as a proxy for COD, but is not accurate enough for some applications. Some research...

Treatment Techniques for Combined Sewer Overflows

During storm events, the flow in a combined sewer system can exceed the capacity and, as a result, a combined sewer overflow (CSO) will occur. During a CSO raw wastewater is discharged to surface water. This wastewater is a mixture of raw sanitary wastewater, raw industrial wastewater and rainwater. The receiving water will get polluted by...
