A data-derived soft-sensor method for monitoring effluent total phosphorus

The effluent total phosphorus (ETP) is an important issue to evaluate the performance of wastewater treatment process (WWTP). To obtain the reliable values of ETP online, a PLS-RBFNN-based soft-sensor system, including the PLS technique and RBFNN algorithm, is developed to monitor the values of ETP in a real WWTP. Experimental results show that the proposed monitoring system can obtain the values of ETP online and own better predicting performance than some existing methods.183
