Biological Phosphorus Removal Options. Biological P removal, especially Enhanced Biological Phosphorus Removal (EPBR) with activated sludge systems, has been studied in depth in recent years. It is considered to be a cost effective and environmentally sustainable alternative to chemical treatment (Acevedo et al., 2012; Nguyen et al., 2013).

Phosphorus Removal Analysis - WWOA

The cost of dolomite to treat 1 m 3 of high-phosphorus wastewater was 0.20 yuan in 2019, which was 45.9%, 25.9%, and 75.9% lower than the costs of MgCl 2, MgSO 4, and CaCl 2, respectively, to treat wastewater. Using dolomite could therefore effectively decrease the cost of removing phosphorus from wastewater through crystallization.
