Análisis del polielectrolito óptimo en el proceso de acondicionamiento de lodos biológicos previo a la deshidratación con filtros banda en la planta de tratamiento de aguas residuales de Ucubamba

Abstract

The process carried out in the Ucubamba sludge dehydration plant is fundamental, since it avoids the contamination of ecosystems that could be affected by their mismanagement. Dehydration contemplates a reduction in the volume and content of water that make up the sludge, so that the sludge can be dehydrated, the plant conditions it with cationic type flocculants. The objective of this work was to find the flocculant that allows obtaining a moisture content in cake with a percentage lower than 70%. Of the 12 polymers considered, 4 were preselected, for which the doses and mixing speed were analyzed in a jar equipment. Once the experimental stage was concluded, a spreadsheet was developed that allowed to know and control key parameters such as: flow rates, concentrations and stirring speeds of the equipment used in the plant process, the different configurations were tested, obtaining the best results two flocculants that serve their intended purpose.
