Recovery of Energy from Toxic and Refractory Wastewater in New Applications of the Upflow Anaerobic Sludge Blanket Reactor and Microbial Fuel Cell
This research suggests an application of anaerobic digestion and electrogenic treatment as a solution for wastewater containing toxic and refractory contaminants. The goal is to convert organic chemicals in wastewater into biogas and electrical power as valuable products that off-set treatment costs for wastewater treatment facilities. Petroleum refinery wastewater (PRW) is a complex mixture containing refractory compounds that potentially can be utilized as the substrate for anaerobic digestion and electric power generation. PRW contains diverse ranges of compounds including benzene, toluene, ethylebenzene and xylenes (commonly known as BTEXs). BTEX compounds are toxic to humans and are confirmed or suspected carcinogens that are classified by the U.S. Environmental Protection Agency as priority pollutants.Thus, the implementation of mentioned approaches would have beneficial consequences for human health and solving the waste problem.
