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 aluminum-based coagulants to the development of
Alzheimer’s disease in human beings (Flaten, 2001). It is therefore
desirable to replace these chemical coagulants with plant-based
coagulants to counteract the aforementioned drawbacks.
