Wastewater is often treated using the activated sludge process. Flocculation and subsequent sedimentation of flocs are vital steps in this process that have direct influence on the quality of the effluent water from wastewater treatment plants. Since cells that remain free-living will decrease the quality of the effluent water it is important to understand(More)
The success of biological wastewater treatment is to a large extent governed by the ability of bacteria to induce floc formation, thereby facilitating the separation of particles from the treated water. We performed studies on the dynamics of floc stability, the desorption of cells from the flocs, and the reflocculation of detached material. The floc(More)
Bacterial cell surface hydrophobicity is one of the most important factors that influence bacterial adhesion. A new method microsphere adhesion to cells, for measuring bacterial cell surface hydrophobicity was developed. Microsphere adhesion to cells is based on microscopic enumeration of hydrophobic, fluorescent microspheres attaching to the bacterial(More)
For autonomous vehicles correct behavior is of the utmost importance, as unexpected incorrect behavior can have catastrophic outcomes. However, as with any large-scale software development, it is not easy to get the system correct. As the system is made up of multiple sub-modules that interact with each other, unexpected behavior can arise from incorrect(More)
