This research assesses the agro based materials like Surjana seed (Moringa oleifera), Nirmali seed (Strychnos pototorum) and maize (Zeemays) as a coagulant aid in conjunction with alum to determine their efficacy in water treatment. Experiments have been conducted simulating a conventional water treatment train consisting of coagulation-flocculation-settling and granular media filtration. They found that filtrate quality has improved with the use of agro-based materials.
