Optimización del Proceso de Elaboración de papel para eliminar la formación de Biofilms en las tuberías de la empresa Familia SANCELA del Ecuador S.A.

Abstract

The optimization of the paper elaboration process was made to eliminate the formation of biofilms in the pipeline of Sancela family company of Ecuador located in the sector of Lasso, province of Cotopaxi. In addition to the verification of the current state of the pipelines of the company it was evidenced biofilms, bad smell, and rejection of paper for this defect, three essays were carried out with bactericides, first, with Dispro 48, with a duration of two months persisting the biofilms; second, with Biocatalyzer Traclean 60, during one month showing an increase of biofilms in the pipes; third, it is tested with a combination between an oxidant sodium hypochlorite and bactericide during three months in which it wasn’t found biofilms in pipes, or rejection of the paper by this defect; to maintain controlled the treatment it was used characterizations of water at the entrance of the process, and dosage tests of sodium hypochlorite and bactericidal; tests made in the laboratory of the biological waste water treatment plant of the company. It was determined that the appropriate treatment for a removal of biofilms from 100 % is the combination of sodium hypochlorite and bactericide. Which allowed to reduce the economic losses of the company in a 100 %, also a better microbiological quality of the paper. The implementation of the treatment allows to improve the efficiency of removal of biofilms by optimizing the process of elaboration of paper in this way is recommended to apply the study performed in Sancela family company of Ecuador and in related companies which will allow to offer a better quality service to the client, as well as it will be provided to the final consumer a better microbiological quality of the paper.
