Treatability of Crude Desalter Wastewater from a Refinery by an Aerated Submerged Biological Filter�
Abstract
The biological kinetic coefficients of a laboratory scale Aerated Submerged Biological Filter (ASBF} which reduced the toxicity of Crude Desalter wastewater were determined by analyzing the data in' the Germain kinetic model. The organic removal vs. organic loading graph for the ASBF data indicated that the data was first order or linear. Thus, the first order Germain model was used to determine the kinetic coefficients. The kinetic coefficients were then used,to determine the volume, surface area of media, and effluent concentrations of full size ASBF to treat Crude Desalter wastewater at a petroleum refinery. During the study, the ASBF was run at organic loading rates from 3.5 g COD/m 2*day to 13.7 g COD/~2 *day with COD removal efficiency in the range of 57.9% to 88.8% and increased toxicity removal, influent LC50 of 57.47% to effluent LC50 of 100%.
