This presentation discusses biological treatment of wastewater from the printing and dyeing industries. It begins with an introduction that defines different types of wastewater and lists group members. It then explains the multi-stage wastewater treatment process including primary, secondary and tertiary treatments. Specific biological treatment methods like aerobic and anaerobic processes are outlined. The presentation concludes that biological treatments take advantage of bacteria to treat a wide variety of contaminants in wastewater, producing effluent and sludge with high fertilizing value that can make the process highly profitable.
