Waterborne Diseases: Unilorin don identifies organisms for purifying water
Olatunji Kolawole, a virologist with the University of Ilorin (Unilorin), has identified novel bioflocculants (organisms) capable of treating water.
According to the Unilorin Bulletin, Mr Kolawole made the discovery while investigating bacteria and viruses associated with waterborne diseases in 2020.
Bioflocculation is a process in which mediation of flocculants is achieved in the presence of microorganisms or biodegradable macromolecular flocculants released by microorganisms.
The publication said the bioflocculants cause the clumping together of dispersed organic particles, which could remove microbes and chemical pollutants from water and wastewater.
It stated that these novel organisms have now been crystallised to increase their efficiency in water/wastewater treatment.
“Kolawole has worked extensively on enteric viruses isolated from humans and water bodies,” it stated. “He has also worked on other public health concerns, including coronavirus, adenovirus, hepatitis virus, human papillomavirus, arboviruses, haemorrhagic viruses, poliovirus and enteroviruses.”
It stated that the significance of the discovery of bioflocculants is that they are degradable, safe, less costly, available and eco-friendly in contrast to chemical flocculants.
The publication explained that the chemical produces toxic sludge and contains heavy metals which destroy human organs.
