GOAL: This PhD project will focus on evaluating and advancing the application of Membrane Aerated Biofilm Reactor (MABR) technology for treating produced water. Current treatment systems, based on conventional activated sludge (CAS) systems integrated with membrane bioreactors (MBR), are effective but energy-intensive and not designed for nitrogen removal. The MABR offers potential advantages over CAS by improving oxygen transfer efficiency and enabling simultaneous nitrification-denitrification (SND), making it a promising solution for future expansions and the production of water suitable for non-potable reuse.CHALLENGE: The Technology Readiness Level (TRL) of MABR for PW treatment is currently low (TRL 3-4), primarily due to its traditional application in municipal wastewater and the unique challenges posed by the complex composition of PW, which includes recalcitrant hydrocarbons and surfactants. This research aims to address these challenges by adapting and optimizing MABR design parameters, initially developed for municipal wastewater treatment, to meet the specific demands of PW treatment.Research Objectives:Characterize the Biokinetics of Nutrient Removal: Investigate the factors influencing reactor startup, nutrient removal, and microbial community selection within MABR systems, using single-fiber MABR flow cells to simulate defined PW compositions.Comparative Evaluation: Conduct a side-by-side evaluation of MABR and MBR technologies for PW treatment, assessing the potential of MABR to enhance treatment capacity as a standalone solution or in combination with MBR.Scale-Up and Process Optimization: Scale up small-scale experimental findings to larger laboratory-scale systems, refining kinetic parameters through standard process operational controls, such as intraluminal pressure, C/N ratio, and hydraulic retention time (HRT).Techno-Economic Assessment: Perform a comprehensive process simulation and techno-economic analysis to compare the cost-effectiveness, operational efficiency, and environmental impacts of MABR and CAS-MBR treatment systems under various operational conditionsCandidate Requirements:A strong academic background in Environmental Engineering, Chemical Engineering, Microbiology, or a related field.Experience or interest in wastewater treatment processes, biofilm reactors, and water chemistry.Strong analytical skills and proficiency in experimental design and data analysis.Ability to work independently and collaboratively within a multidisciplinary team.What We Offer:A unique opportunity to contribute to cutting-edge research in sustainable water management.Collaboration with leading industry partners, including QE-LNG and ConocoPhillips, ensuring the research is both industry-relevant and impactful.Access to state-of-the-art research facilities and resources at HBKU.Competitive stipend (12,000 QAR/3,000 EUR Monthly stipend) and funding for conference attendance and publications.PhD duration: 3.5-4 Years
