AI Article Synopsis
- The study assessed two biopolymer coagulants derived from non-edible plant biomass for their ability to reduce turbidity and chemical oxygen demand in urban wastewater.
- One biopolymer outperformed the conventional chemical coagulant (aluminum sulfate), achieving significantly higher removal efficiencies of 68.7% for turbidity and 86.1% for chemical oxygen demand at an optimal concentration of 10 mg/L.
- The findings suggest that these biopolymers can serve as effective and sustainable alternatives for improving urban wastewater treatment.
Article Abstract
The present study investigated the effectiveness of two biopolymer coagulants on turbidity and chemical oxygen demand removal in urban wastewater. The biopolymers were produced from vegetal biomass using the mucilage extracted from cladodes, and leaves. is an abundant species in Mexico, which is not edible. is an exotic invasive species in Mexico and other countries, which negatively affects the ecosystems where it is introduced. A combined experimental design of mixture-process was selected to evaluate the effectiveness of both biopolymer coagulants regarding aluminum sulfate (conventional chemical coagulant). Results showed turbidity and chemical oxygen demand removal efficiencies of 42.3% and 69.6% for and 17.2% and 39.4% for biopolymer coagulant, respectively, at a dose of 200 mg/L. Furthermore, optimum conditions from the experimental design to reach the maximum turbidity and chemical oxygen demand removal were obtained at an biopolymer coagulant concentration of 10 mg/L, showing removal efficiencies of 68.7 ± 1.7% and 86.1 ± 1.4%, respectively. These results support using as an alternative biopolymer coagulant in urban wastewater treatment.
