Diseño de un sistema purificador de emisiones con filtro de bagazo para disminuir los contaminantes en pollerías de Chorrillos

Abstract

This research proposes the design of an emission purification system based on a filter made from activated sugarcane bagasse, aimed at reducing pollution generated by rotisserie chicken restaurants (pollerías) in Chorrillos, Lima. The methodology was quasi-experimental with a mixed approach, using passive sampling and measurements through the Airecare application, along with experimental tests in a simulated system. The filter was developed through pyrolysis and chemical activation with vinegar, resulting in a material with good adsorption capacity that visibly reduced the smoke plume in terms of color, odor, and persistence in the air. The system, composed of a metal box, a PVC tube, and a fan, effectively simulated a pollería chimney. In parallel, cadmium (Cd) analysis in air revealed concentrations ranging from 0.0108 to 0.0304 μg/m3, all below the Peruvian Environmental Quality Standard (ECA) limit of 0.09 μg/m3, with the highest value recorded at point P1, located on an active chimney.
