Natural Polymeric Coagulants

Water treatment by inorganic coagulants and synthetic polymers poses environmental challenges tied to trace metals and sludge quality/quantity. With the popularisation of chemical precipitation during the last ۵۰ years, these challenges have become more apparent. As a way to combat the environmental challenges posed by the use of inorganic coagulants and synthetic polymers, natural coagulants have been explored for water treatment. Natural coagulants are biodegradable, non-toxic, and do not pose any of the environmental challenges that inorganic coagulants and synthetic polymers do. This literature review aims to research the used of naturally-occurring polymers as coagulants in water and wastewater treatment.
