| Abstract |
Reduction of tannery waste, i.e., trivalent chromium, sulfide and oil and grease components has been accomplished by process change. Protein recovery and hydroclonic separation of solids was shown to be possible in tannery processing in reducing waste loading. All waste load reduction was accomplished without loss of leather quality. Waste characterization through material balance was accomplished. Chemical reactions and engineering design factors provide guidance for other plant scale operation. |
