Module 5 : Major Sources of Water Pollution

Lecture 4 : Dying and Tanning

 

Biochemical and Physicochemical Combination Processes

• Hydrolytic acidification – contact oxidation – air floatation process

• Anaerobic – aerobic – biological carbon contacts

• Coagulation – ABR – oxidation ditch process

• UASB – aerobic – physicochemical treatment process

Cutting-edge Treatment Process

• Photochemical oxidation

• Electrochemical oxidation

• Ultrasonic technology

• High energy physical process

Solutions

• Uniform and strict emission standards

• Minimizing waste

• Technologies based on membrane systems – low capital and operating costs

• Recycling and reuse of textile effluent water

• Improving process management
