Effects of alkaline pretreatment on side-stream enhanced biological phosphorus removal and recovery process

Key Points

• Enhanced biological phosphorus removal is achieved through alkaline pretreatment, optimizing recovery processes.
• Phosphorus recovery improved by 30% with alkaline pretreatment under controlled conditions of wastewater treatment.
• Analysis of wastewater management systems across multiple treatment plants indicated significant nutrient capture.
• These findings highlight the potential for improved environmental sustainability in nutrient management practices.
