Abstract
Access to clean water is the significant need in all nations on the planet in which many people and living live forms pass on because of tainted water related ailments consistently. Health problems caused by alum have been recently reported. Various reports have mentioned the direct and indirect toxic effects of alum in the form of tumours, cancers and allergies. No investigations have been done to discover whether seeds of Trigonella Foenum-graecum and Cuminum cyminum can be used as water coagulants. In order to partially replace alum as coagulant, the combination of Fenugreek seed powder and Cumin seed powder is used as coagulant in water treatment via coagulation-flocculation process. pH and coagulant dosage were identified for the combinations of Alum, Fenugreek and Cumin seed powder. The overall best efficient turbidity removal proportion is studied for both the synthesized turbid water and river water.
