Biochemical Oxygen Demand and Effluent Wastewater Testing

Wastewater discharge is judged against measures such as biochemical oxygen demand, chemical oxygen demand and suspended solids. These tests require careful incubation, dilution and measurement to be reliable. This programme covers the core effluent tests and their quality control.
