Application of Sodium Acetate Carbon Source in Livestock Wastewater Denitrification

Livestock wastewater has high organic and ammonia concentration with unbalanced C/N; after anaerobic+aerobic it may still fail TN. Adding sodium acetate in the subsequent denitrification unit supplements easily-utilized carbon and significantly improves denitrification, lowering effluent TN.

Dosage relates to wastewater C/N and temperature; bench tests are recommended, with reasonable return ratio.
