Soft-sensing estimation of plant effluent concentrations in a biological wastewater treatment plant using an optimal neural network

作者:

Highlights:

• We develop a neural-network-based soft sensor to predict effluent concentrations.

• We estimate primary variables from secondary variables in activated sludge process.

• Principal component analysis is applied to optimal selection of sensor input vector.

• The soft sensor reduces investment and maintenance costs associated with monitoring.
