Özet/Abstract:

In This Study, Experiments Are Conducted

On Leather Tanning İndustry Wastewaters To
Evaluate Efficiencies Of Alternative Schemes Of Physical
-
Chemical Treatment With Regard To Pretreatment
Standards. Carbonation And Protein Removal Are Employed İn Addition To Sulfide Oxidation, Chromium
Precipita
tion, Plain Sedimentation And Chemical Precipitation. Two Samples Are Used From Two Different
Tanneries Processing Cattlehide. Results İndicate That Carbonation And Protein Removal Have Little Effect On
Cod. Tkn Removal İn Protein Precipitation İs About 20

%. Plain Sedimentation İs Found To Be As Efficient As
Chemical Precipitation For All Parameters Except Chromium. However, As The Results Are Evaluated With
Regard To Pretreatment Standards Chemical Precipitation İs Suggested To Be The Method Of Choice To
Meet
The Chromium As Well As Suspended Solids And Sulfide Standards.
