Abstract

The aim of this study was to evaluate the efficiency of organic filters for removing oils and fats present in swine wastewater (SW). Crushed sugar cane, sawdust and parchment of coffee beans were used as filter materials. Metallic barrels measuring 1.30 m tall and 0.58 m in diameter were filled with the respective organic residues and then submitted to application of SW until the filtration rate became less than 0.2 L m-2 s-1. SW samples were collected before and after filtration in order to evaluate the concentration of oil and fats present in the wastewater. According to the results, the organic filters showed promise for removing oils and fats present in swine wastewater, reaching values of 97.2, 88.9 and 82.3% for crushed sugarcane bagasse, sawdust and parchment of coffee beans, respectively. The filters were not sufficiently efficient to meet the CONAMA Resolution no430/2011 referring to the standards for release oil and fat effluents, however they permitted for a considerable improvement in effluent quality.
