Overview
This intensive 3-day course provides a comprehensive introduction to the principles of biological wastewater treatment design, and covering microbial processes, wastewater characterization, and the removal of organic matter, nutrients, and pathogens. Delegates gain practical insight into system components like aeration, mixing, and settling, as well as advanced technologies such as membrane bioreactors, anaerobic digestion, and biofilm reactors. Case studies and interactive sessions reinforce learning and equip participants to design and optimize effective, sustainable treatment systems. Why Should an Individual Attend?
