Applying the ASM3 model for evaluation of control strategies for a biological nitrogen removal wastewater treatment plant

Biological nutrient removal processes for municipal wastewaters have received quite some attention during the past decades, especially due to the introduction of stricter legislation with respect to allowable effluent pollutant discharge limits. The necessity for performance improvement of existing activated sludge wastewater treatment plants (ASWWTPs) has created a need for detailed process model

Feedback control of flow rate from a peristaltic pump using balance measurements

In many biotechnological processes it is important to perform exactdosing of the substrate into the bioreactor. The idea in this paper is to use the measurements from a balance to control the flow rate, since there is no access to the flow itself. The goals of the controller are several: it should be capable of handling load disturbances acting on the pump, measurement noise and even shocks acting
