Improvement of Water Quality Parameters Using Moringa Seeds and Activated Zeolite in a Simple Brackish Water Filter Prototype
Abstract
Providing a cheap and drinkable water is a major problem for people living in brackish water coastal areas. Residents usually buy water from refill water depots or are forced to use slightly brackish well water for cooking and drinking purposes. Consuming water that contains high levels of salt and other contaminants can be harmful to health in the long run. This study aims to produce a simple brackish water filter that is cheap and can be operated on a household scale to meet the cooking and drinking needs of people in coastal areas. The filter tool is made using filter materials in the form of NaOH activated zeolite, Malang blacksand, greensand, activated charcoal and sponges. Deposition of dissolved particles using moringa seed powder is done before the water is put into the filtering process. Filtration was carried out with a duration of 4, 8, 16 and 32 hours. Salinity, pH and DO of water before and after filtration were measured for each filtering duration, while other parameters were only measured for filtered water with the period of 32 hours. The filter successfully improved the parameters of salinity, pH, turbidity, iron content, hardness, chloride content and organic matter content and can be used as drinking water by cooking it first to remove the chloride content which is still above the maximum specified standard.
