Developing countries and third world countries (including some Muslim counties) are facing potable water supply problems because of inadequate financial resources. The cost of water treatment is increasing and the quality of river water is not stable due to suspended and colloidal particle load caused by land development and high storm runoff during the rainy seasons especially in a country like Malaysia. During the rainy seasons the turbidity level increases and the need for water treatment chemicals increase as well, which leads to high cost of treatment which the water treatment companies cannot sustain. As a result , the drinking water that reaches teh consumer is not properly treated. Therefore , its of great importance to find a natural alternative to find a natural alternative for water coagulant to treat the high turbidity. It has been found that Moringa oleifera is the best natural coagulant discovered yet, that can replace alumunium sulphate which is used widely all around the world. This study is focusing on Moringa oleifera seeds to find the active contituents which are responsible about the coagulation mechanism and improving the coagulation property.
