Biosensors can be used in wastewater treatment to measure the biological response of activated sludge to disturbances. Biosensors convert biological responses into electrical signals and can detect organic carbon, nitrogen, and mixtures. They have two main applications - online sensors to obtain information about wastewater treatment plant operations, and more advanced dynamic models. Biosensors have advantages like small volume, ease of construction, and ability to be used at low oxygen levels. Understanding biological interactions in wastewater treatment is important to optimize plant operations and effluent quality with minimum costs.

Biosensor o Defined as sensors that allow the measurement and interpretation of the biological response of activated sludge to a known disturbance. o Which converts a biological response into an electrical signal o Detects, records and transmit
• To obtain specific information about one or several activated sludge processes. • This information can serve as plant performance indicators. • Most often in the form of a substrate addition : Purpose i. organic carbon, ii. nitrogen, iii.mixtures,
Working principle a – Bio-element b – Transducer c – Amplifier d – Processor e – Display
Application • The application of biosensor in wastewater treatment described about removal of COD and N removal processes • Divided into two direction : i. On-line sensors - To obtain information about wastewater treatment plant ii. More advanced dynamic models
Respirometer
Application of biosensor in wastewater treatment
Advantages • Small volume • Ease from construction • Ability to be used at low pO2 values • The ability to rapidly change the composition of the buffer in which tissue slices are suspended.
Conclusions • Full understanding of the complicated biological interactions in a wastewater treatment plant is essential to optimize treatment plant operation, aiming at reaching a good effluent quality against minimum
