Quick sand filtration in restaurant waste treatment with coconut fiber and activated carbon media: application of Van der Waals Force

Abstract

Domestic liquid waste has become the leading cause of aquatic pollution, with a percentage of 60-70%. One of the media that has the potential to process water is coco fibre. This study aimed to analyze the Effectiveness of both media in reducing restaurant waste. The experiment was conducted with variations in the Thickness of coco fibre and activated carbon media of 10, 15, and 20 cm and sand 40 mesh of 10 cm. The addition of sand media proved more effective in meeting quality standards with the Effectiveness of the reduction of Total Suspended Solid (TSS), Chemical oxygen demand (COD), and turbidity, the highest obtained at the Thickness of coco fibre media 20 cm activated carbon 20 cm, and sand 40 mesh 10 cm, which is respectively 95.78, 93.04, and 98.72%, which is influenced by the Thickness and time of contact of waste with the media.
