Understanding Bio-Augmentation for UASB Treating PTA (Purified Terephthalate Acid) Wastewater Through Econgenomic Tools
PTA is used as a raw material to produce many high-value daily products like polyethylene terephthalate (PET) and textile fibers. The wastewater generated through the BP-invented purified terephthalic acid (PTA) process is treated by an anaerobic process known as up-flow anaerobic sludge bed (UASB) reactor, where PTA-degrading microbial community is present in a form of granules. The main objective of this project is to use ecogenomics tools to improve the understanding on the microbial ecology behind PTA degradation and during bio-augmentation, leading to better process performance and cost saving with UASB reactors.
