CHARACTERIZATION OF CESSPOOL WASTE DEPLETED OF CITY OF ITUMBIARA AT STATE OF GOIÁS

Abstract

This study has evaluated the quantitative and qualitative features of a cesspool waste before being launched into a wastewater treatment plant, located at Itumbiara city (ETE-Itumbiara), interior of the state of Goiás. It was detected a large variation of the waste characteristics, presenting coarse solids and sand, resulting in 1.6m³ of retained waste over a total of 1,872.5 m³ of a total cesspool waste received, representing 0.064% of the average flow treated by ETE. Regarding the physicochemical parameters, the pH and temperature presented lower variation, and the settling solids and COD showed a higher coefficient of variation, followed by oils and greases and total solids. It was also observed that the lower the pH the higher the concentration of oils and greases.
