The Effectiveness of Moringa Seed Powder as Coagulant in Reducing Turbidity of Water Containing Iron Ion in 2017

Ground water is a source of clean water that is often used by people for daily activities. Physically, clean water is colorless, odorless, tasteless, and not turbid. Turbidity and levels of iron ions in ground water can be lowered by using moringa (Moringa oleifera) seed powder as coagulant. Niazynin A and Niazynin B as well as 4-Alfa-4rhamnosxylopsi-benzil-isothioncyanate in moringa can neutralize mud and metal particles on ground water. Moringa seed powder as coagulant is used to coagulation process with jar-test. Based on the experimental test, the yield of turbidity degradation was effective at concentration of 1140 mg by 68%, which can decrease the iron ion content by 78% with the average temperature of 30.4°C and the average pH of 6.5. The height of coconut shell charcoal on a fast-sand sieve of 15 cm to 25 cm is effective as an absorbant in removing the residual flavor and odor of the moringa seed powder after the coagulation process.
