The formation of biofilms on surfaces exposed to water has had significant impacts on wastewater treatment technology. Biofilms are used advantageously in wastewater treatment as rotating biological contractors to degrade harmful organic and inorganic materials. However, biofilm formation on equipment designed to inspect water quality, such as a passive sampler, can alter calculated pollution concentrations. This project investigates the effect of salt and heavy metals on a slowly rotating biological contactor and the effect of a strong magnetic field on a quickly rotating biological contactor. The extent of biofouling on a passive sampler is also examined.
