实物特征:Introduction. The use of biopolymers in effluents treatment allows to control the environmental impact associated with agroindustrial wastewater discharge. Objective. To evaluate the effectiveness of chitosan as a natural coagulant in the treatment of palm oil production effluents. Materials and methods. The following parameters were determined: Chemical Oxygen Demand (COD), total suspended solids (TSS) and volatile solids (TVS), turbidity and fats and oils (GYA) in wastewater associated with palm oil production from the municipality of Agustín Codazzi in the department of Cesar (Colombia), by the jar test assay. Chitosan was applied in doses of: 100, 200, 300, 400, and 0 mg L-1 at three pH levels 4, 5, and 6 of the water. A completely randomized, two-way, fixed effects experimental was implemented. A multivariate analysis of the physical-chemical parameters of industrial effluent was used for data analysis. The study was conducted in 2012. Results. Chitosan allowed a reduction of more than 87 % turbidity, COD, TSS, TVS and fats and oils in all coagulant doses. While the control (0 mg L-1) was statistically different (p<0.05) to all the treatments. In the multivariate analysis of the data, the principal component 1 (PC1) explained 79.3 % of the total variance of the variables. Conclusion. Doses of 100, 200, 300, and 400 mg L-1 of chitosan evaluated as a natural coagulant in water treatment, decreased the concentration of pollutants in effluents associated with palm oil production.
