In South Africa, the disposal of winery and distillery effluent into rivers, streams and onto soil is regulated by various laws and non-compliance with this legislation could result in liability penalties of hundreds of thousands of rands and even to closure of plants. Different types of bioreactors have been designed to address this problem. Biofilms form an intricate part in COD breakdown by various bioreactors. However, current systems lack sufficient surface area on which biofilms can form. The objective of this project will be to evaluate the application of increased surface area in biological reactors, for optimum biofilm formation, for the primary treatment of winery effluents.
