Experimental Study on the Efficiency of Moving Bed Biofilm Reactor in Treating Ethylene Glycol, M.Sc. Thesis Sharif University of Technology ; Borghei, Mehdi (Supervisor) ; Vossoughi, Manoochehr (Supervisor)
Abstract
The removal of ethylene glycol, one of the most widely used antifreez, with moving bed biofilm reactor (MBBR) was studied. Beside of ethylene glycol, the synthetic wastewater contained molasses and other salts as nutrient source. The packings were composed of polyethylene and shaped like small cylinders with a surface area of 500 m2 per m3 bulk volume of carriers(KMT). The COD of the feed was adjusted by varying the ratio of ethylene glycol to molasses. The total COD was 1252.5, 1345 and 1500 mg/L. The resulted showed that when the biofilm grows on the packings and its thickness is good enough, the removal efficiency increased. The increase was attributed to higher concentration of biomass...
