Effectiveness of Moringa Oleifera Seed as Phytocoagulant in Wastewater Treatment of Batik Industry

Abstract

Investigating effectiveness of Moringa oleifera seed as environmentally-friendly phytocoagulant to reduce pollutant in batik industry wastewater has been conducted for period of times. This study found that processing coagulation flocculation independently was proved ineffective for batik industrial wastewater treatment. pH was variable that met effluent standards set by government, while other two variables, BOD and COD, did not meet the standard set, as both increased along with the increasing dose of Moringa oleifera. The increase of BOD and COD was probably caused by the oil content which was not extracted from the seeds. Although TDS variable showed significant reduction between 66%-92%, it did not meet effluent standard set by government. This study suggested that future research should add an independent variable, such as variations of rapid stirring, pH variations, or oil extraction. In addition, combining several processing methods and adding different dose of Moringa oleifera seeds can be also another option. These are to possibly see the effectiveness of the flocculation-coagulation process independently as well as the combination of them in the wastewater treatment of batik industry.
