Influencia de las fracciones de materia orgánica sobre el desempeño de un sistema de tratamiento de agua residual de una industria papelera

Slowly biodegradable organic matter represents the bulk of organic matter content of pulp and paper mill wastewater which can influence the performance of treatment systems. The organic matter fractionation is a useful tool that generates information for optimize treatment processes of wastewater. Organic matter fractionation study was carried out. Biodegradable soluble, biodegradable particulate, non-biodegradable soluble and non-biodegradable particulate fractions were identifies in effluents of primary clarifier, facultative aerated pond and sedimentation pond. Results of this study show that organic matter non-biodegradable/total organic matter ratios of the influent were 69% while biodegradable fraction was 31%. Primary clarifier removed significantly the non-biodegradable fraction it was key for biological treatment. The biodegradable soluble fraction was mostly removed in facultative aerated pond (44% to 12%). The effluent was polished in the sedimentation pond, mainly particulate organic matter fraction. Only a small percentage of non-biodegradable organic matter was adsorbed by facultative aerated pond biomass, the fraction of this organic matter accounted for 19% in the influent and increased to 45% in the effluent.
