Its application includes removal of dissolved chemical species and turbidity from water via addition of
conventional chemical-based coagulants, namely, alum (AlCl3), ferric chloride(FeCl3) and poly aluminium chloride
(PAC).While the effectiveness of these chemicals as coagulants is well-recognized, there are, nonetheless,
disadvantages associated with usage of these coagulants such as ineffectiveness in low-temperature water, relatively
high procurement costs, detrimental effects on human health, production of large sludge volumes and the fact that they
significantly affect pH of treated water. There is also strong evidence linking aluminium-based coagulants to the development of Alzheimer’s disease in human beings. It is therefore desirable to replace these chemical coagulants
with plant-based coagulants to counteract the afore mentioned drawbacks [5].
