Phosphorus removal in seafood processing wastewater by lab-scale Bardenpho 5-stage model

Abstract

Seafood processing wastewater usually has high phosphorus concentration, and almost Vietnam seafood processing wastewater treatment plants have low phosphorus removal efficiency. The study has designed a Bardenpho 5-stage lab-scale model to remove phosphorus in seafood processing wastewater with different flows: 30 L/day, 50 L/day and 70 L/day. In optimal flow 50 L/day, the treatment efficiencies of COD, NH₄⁺, TP of Bardenpho model were 93.9%; 81.7%, 69.3%, respectively.
