Biocoagulants are widely used for the treatment of contaminated water in less urban areas because they appear to be lower in carrying cost-treated coagulates when compared to artificial coagulants. This study focuses on the coagulation potential of Philippine lime waste, specifically on its utilization as a natural coagulant or biocoagulant for domestic wastewater treatment. Jar testing was carried out with optimal parameters, including a coagulant dosage of 15 mg/L, a mixing speed of 80 rpm, and a mixing time of 15 min. The results showed that Philippine lime waste biocoagulant with a pectin content of 4.08% could reach a biocoagulation or turbidity removal efficiency of 51.30%. Nevertheless, the COD removal efficiency only reached 7.13% indicating room for further investigations using the Philippine lime waste biocoagulant. The relationship between pectin content and turbidity removal efficiency emphasizes the need of understanding the composition of biocoagulants used in water and wastewater treatment procedures. The study highlights the potential of citrus waste materials as reliable and effective coagulants for water and wastewater remediation, thus promoting the advancement of sustainable wastewater treatment systems. Overall, biocoagulation using Philippine lime waste would be a sustainable wastewater treatment technique due to the utilization of a waste material as a potential biocoagulant.
