Abstract
The use of conventional chemical based coagulants increases residual levels of chemical products. That is why they are considered harmful to the environment and toxic to human’s fauna and flora (Farooq et al. in Bioresour Technol 101:5043–5053, 2010). In addition, they have a relatively high procurement costs. The cost and the environmental side effects of these compounds led many researchers to investigate the possibility of using plant-based coagulants in water and wastewater treatment (Joseane et al. in Plast Polym Technol 2(3):55–62, 2013). Naturally occurring products are biodegradable and are presumed safe for human health (Muralimohan et al. in Int J Res Eng Technol 2(2):15–20, 2014).
