About this course
The course, “Introduction to Treatment of Tannery Effluent” is designed for training institutions, private companies, and individuals that require an understanding of effluent treatment methods in the leather industry. The course is recommended to be used in a blended approach via classroom instruction using training content or self-learning along with an allocation of time for hands-on application in the laboratory. There are 5 modules in this course as below:
- Module 1: Load, norms, in-house treatment. This module will explain the aim of effluent treatment; pollution load and the main wastewater quality parameters; typical discharge norms. It will also offer a general overview of the treatment of tannery effluents, segregation of streams, treatment of spent liming floats, and treatment of chrome-bearing floats
- Module 2: Treatment within tannery compound. This refers to the pre-treatment for discharge into the common effluent treatment plant (CETP) collection network, and physical-mechanical (primary) treatment for discharge into municipal sewage.
- Module 3: Sludge dewatering. This module explores sludge thickeners, sludge pumps, filter press, centrifuge, belt filter press, flow-chart of physical-chemical treatment, and sludge drying beds.
- Module 4: Biological (secondary) treatment. This module looks into activated sludge, aeration devices, oxidation ditch, and the flow-chart of the biological treatment
- Module 5: Occupational safety and health (OSH) in CETP, and its costing and management
Training institutions, private companies, and individuals that require an understanding of effluent treatment methods in the leather industry.
