Summary of "Performance evaluation of a lab-scale moving bed biofilm reactor (MBBR) using polyethylene as support material in the treatment of wastewater contaminated with terephthalic acid."

Untreated terephthalic acid (TPA) wastewaters with high organic loads will cause severe environmental pollution problems. In this study, a lab-scale moving bed biofilm reactor, where biomass of Delftia sp. WL-3 is attached to polypropylene carrier elements, has been tested for TPA bioremediation at 25-27 °C. The system achieved stable operation after a short 15-day start-up period. During the operation period of 65 days, stable chemical oxygen demand (COD) and TPA removal efficiencies of 68% and 76% were maintained with an organic load rate (OLR) and hydraulic retention time of 2.5 kg COD·(m·d) and 24 h, respectively. In addition, the Scanning Electron Microscope (SEM) showed that high-densities of WL-3 biomass accumulated on the surface of the carrier and formed a rich biofilm, indicating polypropylene carrier can improve the degradation efficiency. On the contrary, the biodegradation ability of stain WL-3 without the polypropylene carrier declined significantly with removal efficiencies of 10% and 15% for COD and TPA. Furthermore, the system exhibited excellent robustness to different OLR and influent matrix ratios, indicating its potential for applications in the treatment of TPA-containment wastewater in the field.

The initial intended use was to provide more efficient assessment of treatment response in clinical psychopharmacology research; however, the scale was readily adapted to other uses.
