Animated Visual Training Tool

Technology has gone a long way during the past decades. Information and communication technology (ICT) should make visible the impact of the present status of professional education and training applicable for leather and the manufacturing of leather products. Conventional training and learning methods and routinely suggested course durations, forms and arrangements suit neither today’s would-be employees or industrial operations.

In spite of some initiatives by various institutions, education and training in leather-based industries has not made full use of the available technology.

UNIDO’s development of an animated Visual Training Tool (VTT) aims to do exactly this: improve training efficiency through incorporating today’s available technology.

VTT is serves as a practical training tool for UNIDO workshops in developing countries, mainly targeting leather technologists, tannery managers as well as decision makers of different profiles. It is also expected to help the staff of EPAs and members of NGOs in better understanding key issues and principles of the treatment of tannery waste waters.

The presentation draws extensively from UNIDO’s paper Introduction into Treatment of Tannery Effluents, What every tanner should know about effluent treatment and other UNIDO studies and reports.

To facilitate understanding, the topic is split into blocks covering the main treatment steps and operations.

Chapters

The animated presentation will, include the following chapters:
1.   Load, norms, in-house treatment
The aim of effluent treatment; pollution load and the main waste water quality parameters; typical discharge norms; general overview of the treatment of tannery effluents, segregation of streams, treatment of spent liming floats and treatment of chrome-bearing floats
2.    Treatment within tannery compund
Pre-treatment for discharge into CETP collection network, physical-mechanical (primary) treatment for discharge into municipal sewage.
3.    Sludge dewatering
Sludge thickeners, sludge pumps, filter press, centrifuge, belt filter press, flow-chart of physical-chemical treatment, sludge drying beds.
4.    Biological (secondary) treatment
Activated sludge, aeration devices, oxidation ditch, flow-chart of the biological treatment.
5.    Occupational safety and health (OSH) common effluent treatment plant (CETP) costing and management
Monitoring, OSH at work, CETP collection, CETP costing, flow-chart of fully fledged treatment;

UNIDO’s Visual Training Tool was prepared under the project Reduction of environmental threats and increase of exportability of Bangladeshi leather products, which was co-funded by the European Union and implemented by SEQUA (lead), BTA, BFLLFEA, bfz, DCCI and UNIDO.
