Nitrogen removal from tannery wastewater by protein recovery.
Nitrogen removal from tannery wastewater by protein recovery.

Nitrogen, removal from wastewaters has gained importance in recent years. In this paper protein precipitation and recovery potential of leather tanning industry wastewaters were experimentally evaluated. A protein profile for all sources was prepared. Liming was determined to be the most important protein source.
