What is it about?

Reliable and inexpensive monitoring of nutrients has been an important barrier for the implementation of advanced control strategies for optimal MBBR process operation. This work describes a cost-effective option to upgrade the online monitoring system in a multi-stage MBBR process for biological phosphorus removal in wastewater.

Why is it important?

A cost-effective method for monitoring phosphates and COD in a continuous multi-stage MBBR pilot plant. An efficient method for successive recalibration of soft-sensors was discussed.


The article was a result of the collaboration between the research groups of Norwegian University of Life Science and the Norwegian University of Science and Technology. Working as a part of an interdisciplinary research team has helped combine the expertise in bio-chemistry, processes design, control, and digital water and produce a practically applicable method to enhance the operation of a multi-stage MBBR process.
