Many industries generate wastewaters that are not suitable for conventional biological wastewater treatment. This could be due to the presence of ‘hard to degrade’ compounds such as pesticides, chlorinated and volatile organic compounds or high concentration of detergents or fats. Other contaminants, such as salts, acids, alkali and metals, may also be toxic to the microorganisms and thus jeopardise the treatment. These wastewaters must therefore be treated before they can be sent to a wastewater treatment plant. The interesting challenge is that there is no ‘standardised approach’, instead a variety of strategies are required to deal with these various contaminants.

This presentation will take you through a range of treatment technologies aimed at a different wastewater compositions including treating VOC in acidic wastewater, the microbial degradation of chlorinated organics, photocatalytic oxidation of dye-wastewaters and the application of enzymes to treat slaughterhouse fatty wastewaters.
