An activated sludge process is being used to treat wastewater from a small town of 50,000 people, which includes intermittent industrial discharges that may have a toxic impact on the performance of the wastewater treatment plant(WWTP) a) What type of online equipment would you recommended be installed for early warnings of wastewater treatment failutre? b) Which parameters would you recommend be measured and where would these be positioned in the WWTP?
The waste water collected from a small town of 50,000 people incluinding an intermediate industrial discharge will have an toxic impact on the performance of the Treatment plant.
The initial check for the same would be pH and BOD. Since the activated process is used to degrade the biological method present in the water in the form of flocs and suspended solids.
Online BOD euipment should be used at the discharge of the WWTP in order to check safe functioning of the system.
Presence of degradable matter in water will cause odour and colour to the water. This will also have impact on COD of the water.
