Bio
Dr. Khalekuzzaman, P.Eng. is a civil and environmental engineer with more than twenty (20) years of extensive research, professional and academic experiences both in Bangladesh and Canada. His current research focuses on waste to energy, environmental biotechnology, anaerobic wastewater treatment, faecal sludge management, hydrothermal liquefaction (HTL), algal biofuels. Currently, he is leading the “Sludge to Oil (SOIL)†research group and is working as the Principal Investigator of the SOIL hydrothermal liquefaction (HTL) Pilot Plant funded by Bangladesh Energy and Power Research Council (BEPRC), Ministry of Power, Energy, and Mineral Resources, Government of the People's Republic of Bangladesh. His research interest focuses on high-quality biocrude production from different wet-waste streams (microalgae, fecal sludge, organic solid waste, plastic waste, etc.) and peat.
In addition, he worked as a senior environmental project manager/engineer for more than ten (10) years in the water and environment division at Canadian construction and engineering giant SNC-Lavalin Inc., one of the leading engineering and construction groups in the world. At SNC-Lavalin, he used to manage large scale complex environmental projects related to contaminated hydrogeological study, remediation of contaminated groundwater, water supply and sanitation project, water and wastewater treatment, environmental health and safety, liquid hazardous waste management, environmental compliances, environmental site assessment and complex remediation of contaminated lands. He has extensive management experience through various environmental projects (from $400K to $5M) from planning to implementation stages.
His research interest also focuses on hybridization of anaerobic wastewater treatment systems (e.g., Anaerobic Baffled Reactor (ABR), Upflow anaerobic sludge blanket (UASB), etc.); and optimization of waste to energy production through HTL process; microalgae biofuels/biocrude production focusing on low-cost microalgae harvesting techniques. In addition, he is keen on finding a low-cost faecal sludge treatment technology/approach resulting in a high-value end product for sustainable fecal sludge management (FSM) system in the context of subtropical-tropical climate regions. Moreover, he was former (2019-2022) the program coordinator for the Global Sanitation Graduate School (GSGS) Program with IHE Delft, Netherlands for MSc Programme in Sanitation, which is funded by Bill & Melinda Gates Foundation (BMGF). He is also an active participating member of the Sustainable Urban Water and Sanitation (SUWAS) program since held in Sweden & Cambodia (2016) jointly organized by NIRAS AB and WaterAid, Sweden, on behalf of the Swedish International Development Cooperation Agency (SIDA). He is also working as a project director on several projects related to advance wastewater treatment towards meeting Goal 6 of Sustainable Developments Goals (SDGs) for Bangladesh funded by the University Grant Commission (UGC), Bangladesh, and WaterAid Bangladesh.
He also works as a technical advisor/team leader for the design and construction of WASH projects, including industrial (e.g., textile) wastewater/effluent treatment plants in order to provide a potentially low-cost, highly efficient, sustainable effluent treatment process for a safer environment. As a researcher, he has high-class research experience treating water and wastewater. He was also involved in designing and implementing an in-situ groundwater bioremediation treatment system for the complex situation of contaminated industrial lands, bio-pile design, and evaluation for contaminated soil, Remediation by Natural Attenuation (RNA) for contaminated groundwater.
He is an expert on waste to energy, both domestic and industrial wastewater treatment processes for his comprehensive research work and practical experiences in several environmental projects. He is proficient in the environmental field and laboratory analyses for water, wastewater, microalgae characterization, microalgal lipid extraction, biocrude characterization and analysis including the Quality Assurance/Quality Control (QA/QC) sampling program. He has about one and a half years of laboratory testing experience in a Canadian laboratory and more than five years in a Bangladesh laboratory for water quality parameters of wastewater samples, according to “Standard Methods for the Examination of Water and Wastewater.†Dr. Khalekuzzaman was a licensed professional engineer in Ontario and Manitoba, Canada, and a fellow member of the Institution of Engineers, Bangladesh (IEB).

My current research focuses on the followings:
(1) hybridization of anaerobic wastewater treatment systems (e.g., Anaerobic Baffled Reactor (ABR), Upflow anaerobic sludge blanket (UASB), etc.); and
(2) optimization of microalgae biofuels production focusing on low-cost microalgae harvesting techniques (e.g. gravity settling, auto/bio flocculation, etc.); and
(3) optimization of hydrothermal liquefaction process.
The primary objectives of my research are to develop a simplistic sustainable approach for wastewater treatment and bioenergy (as biofuels) production for most of the developing countries located in subtropical-tropical regions.
