The simple filtration unit in reducing parameters of restaurant wastewater

Abstract Restaurant wastes have high organic content that often pollute the environment. The filtration process is one method that can be done to reduce the restaurant wastes. The simple filtration process has been proven to be effective and capable of reducing contaminant contained in waste water. This study aims to determine the effectiveness of the simple filtration unit using some media for filtration and reducing some parameters of restaurant waste water. The Filtration experiment was carried out using variations in media with the thickness of 5, 10, and 15 cm. By using of media thickness with 15 cm given the best result in decreasing BOD, COD and turbidity (BOD was 93.4%, COD was 83.86%, and turbidity was 90.4%). The media thickness of 5 and 10 cm had given the best result of TSS parameter which was 99.22%. The media thickness of 5 cm also given the best result in oil and fat parameter, the result showed was 94.02%. The results of this study can be a solution in the treatment of restaurant liquid waste with the help of a filtration system.
