Chitosan coagulant: coagulation/flocculation studies on turbidity removal from aquaculture wastewater by response surface methodology

Popis výsledku v původním jazyce

Aquaculture wastewater treatment currently relies heavily on chemical coagulants to facilitate processes such as coagulation, flocculation, and sedimentation. However, eco-friendly alternatives are needed to make the industry more sustainable. In this study, we explored the potential of chitosan extracted from Pacific whiteleg shrimp, Litopenaeus vannamei shell as a biocoagulant to treat aquaculture wastewater. The coagulation/flocculation behaviour of chitosan was studied for turbidity removal using a suspension of kaolin clay and aquaculture wastewater. The impact of initial turbidity, chitosan dosage, and pH of the kaolin clay suspension was examined using one-variable-at-a-time analysis. The results were then used to establish the range for the Box-Behnken design in response surface methodology. Chitosan was found to be effective in removing turbidity, with 97.58 +/- 0.02% removal achieved in the kaolin clay suspension at 1 mg/L chitosan dosage and pH 7. In the aquaculture wastewater analysis, 10 mg/L chitosan dosage resulted in 90 +/- 0.72% turbidity removal. The Box-Behnken design in response surface methodology resulted in an optimal turbidity removal of 94 +/- 0.61%, achieved using a chitosan dosage of 18.25 mg/L, pH 7, sedimentation time of 18.1 min, and desirability of 0.974. The optimal model for determining the relationship between variables was a quadratic polynomial model with R-2 = 0.9908. Our study demonstrates the effectiveness of chitosan as a biocoagulant for turbidity removal from aquaculture wastewater. These results offer promising potential for the development of more sustainable alternatives to chemical coagulants in the industrial sector.
