Some Guidelines for pH Control of a P-recovery Pellet Reactor

Abstract

Emphasis in recent years has been focused on improving processes which lead to enhanced phosphate recovery. This paper studies the precipitation features of calcium phosphate in a fluidized bed reactor in a concentration range between 4 and 50mg/L, and establishes the conditions for optimum phosphate removal efficiency. A two level modeling methodology is proposed and used for the determination of a control strategy of the unit pilot.
