This document discusses using Moringa oleifera seeds as a natural coagulant for water treatment. It begins by providing background on the need for affordable water treatment in developing countries. It then describes how Moringa oleifera seeds have been shown to be an effective natural coagulant that can replace aluminum sulfate. The study focused on isolating bioactive constituents from Moringa oleifera seeds to improve their coagulation properties. Jar tests showed the processed Moringa oleifera reduced turbidity by 95-99% in river water samples, using lower dosages than chemicals. The results indicate Moringa oleifera's potential as a sustainable alternative coagulant.
