During the course of plants’ screening program in our laboratory,
crude extract from common bean (Phaseolus vulgaris) seed
was applied for water turbidity removal while partially purified
coagulant has shown high coagulation efficiency followed by low
organic load (Antov et al., 2010). Seed of common bean has food
grade nature and contains no oil, so, delipidation step is not necessary
which is beneficial for both economic and environmental
reasons. Considering this common bean is a promising source of
natural coagulant for water treatment.
