1. Control of Nitrogen Removal in Activated Sludge Processes
Abstract : More stringent requirements on nitrogen removal from wastewater are the motivation for this thesis. In order to improve treatment results and enhance cost-efficient operation of wastewater treatment plants, model based control strategies are presented. A Java based simulator for activated sludge processes (JASS) is presented. READ MORE

2. Feeding Strategies Based on Probing Control for E. coli and V. cholerae Cultivations
Abstract : The recombinant DNA techniques have made it possible to produce many different proteins for a wide range of applications. The vector encoding for the recombinant protein is often inserted in the bacterium E. coli as it is a well studied and a well-known organism. To achieve a high productivity, it is important to reach a high cell density. READ MORE

3. Realising full-scale control in wastewater treatment systems using in situ nutrient sensors
Abstract : Abstract A major change in paradigm is taking place in the operation of wastewater treatment plants as automatic process control is becoming feasible. This change is due to a number of different reasons, not least the development of online nutrient sensors, which measure the key parameters in the biological nutrient removal processes, i.e. READ MORE

4. Automated Manufacture of Fertilizing Agglomerates from Burnt Wood Ash
Abstract : In Sweden, extensive research is conducted to find alternative sources of energy that should partly replace the electric power production from nuclear power. With the ambition to create a sustainable system for producing energy, the use of renewable energy is expected to grow further and biofuels are expected to account for a significant part of this increase.

5. Probing Control of Glucose Feeding in Escherichia coli Cultivations
Abstract : Production of many proteins can today be made using genetically modified organisms. One of the most frequently used host organisms is the bacterium Escherichia coli. A difficulty encountered in cultivations of E. coli is the accumulation of the metabolic by-product acetate which inhibits cell growth and production of a desired protein. READ MORE
