Yet, despite all preventive measures, there is still a considerable amount of pollution load to be dealt with by the end-of-pipe methods.

The purpose of this booklet is to help a tanner or a tannery manager possibly a well-trained leather technologist to get familiarized with basic principles and methods of treatment of tannery effluents.
