About the Authors
clean technology of wastewater treatment through biodegradation of domestic and
industrial wastewater involving membrane filtration, and heavy metals removal from
contaminated water using biosorbents. Others include membrane development from
bioresource materials for applications in fuel cells. He has published over 21 papers
in accredited journals, 8 book chapters and attended several local and international
conferences. He has examined more than ten dissertations from various universities
in South Africa and graduated Masters’ and Ph.D. students.
Dr. Tumisang Seodigeng is a senior lecturer at Vaal University of Technology,
where he leads research in the field of Product Design and Process Systems Engineering in the Department of Chemical Engineering. He has more than 15 years’
experience in design, operation, research and development, as well academic research
and teaching in the field of chemical engineering. Tumi holds a doctorate from the
University of the Witwatersrand (2006), where he also obtained a B.Sc. in chemical
engineering (2000). He has been involved with developing numerical models and
computational tools for complex chemical engineering processes since his graduate
studies. During his Ph.D. studies, he developed the RCC algorithm, a method that
can solve virtually any process systems convex optimization problem with reliable
robustness and speed. He later joined the University of the Witwatersrand in 2005 as
a research officer and lecturer in chemical engineering process synthesis and optimization as well as computational methods for chemical and metallurgical engineers.
Tumi later joined Sasol Technology Research and Development, in 2007 where he
continued to model and develop innovative computational tools for complex chemical engineering systems for the petrochemical industry. His key responsibility areas
included catalyst activity and selectivity modelling, reaction engineering and reactor
modelling. He also worked in the design, commissioning, start-up and operation of a
number of petrochemical processes at SASOL. In 2012, returned back to academia
as a senior lecturer in the Department of Chemical Engineering at University of
Johannesburg. In 2015, he joined Vaal University of Technology.
Engr. Ikenna Emeji hold a B.Eng. in chemical engineering department of Enugu
State University of Science and Technology, Enugu, Nigeria. After his youth service
in Kaduna State Water Board, he joined an oil serving company Port-Harcourt,
which specializes in providing drilling muds to drill oil wells. He started his research
programme in the Department of Civil and Chemical Engineering, University of
South Africa (UNISA) where he obtained a Magister Technologiae (M.Tech.) in
chemical engineering. He is currently studying for a Ph.D. programme in chemical
engineering department at Vaal University of Technology, South Africa, where he is
also working as a graduate assistance attached to the Thermochemical Processes and
Waste Utilization Research Group (TPWUG) of chemical engineering department.
He has attended conferences to give both oral and poster presentations. He has
also published journal papers and written book chapters in the areas of wastewater
treatment. Ikenna is an active member of the South African Institute of Chemical
Engineers (SAIChE) since 2018 and also a member of Water Institute of South Africa
(WISA, 2018)
