Abstract

In Indonesia, there are various environmental pollutants, one of which comes from household activities. Therefore, various ideas emerged in dealing with the polluted environment. One of them is using the phytoremediation method. In this study using wood apu (pistia stratiotest l) and water spinach (ipomea aquatica) grown using a hydroponic system. In hydroponics, there are two systems, namely DFT (deep flow technique) and NFT (nutrient film technique). In this study, using two kinds of systems, with the addition of aeration and without aeration, with variations in the distance between plants of 5cm, 10cm and 15cm and using two types of plants, namely water spinach and apu wood. The length of the study was 15 days, the first 7 days of acclimatization and the last 8 days of the main study. The results showed that the most optimal treatment was found in apu wood plants with a distance between plants of 5cm, with the addition of aeration and using the DFT system to achieve BOD 58.41%, COD 32.36% and TSS 62%.

Abstract

Currently, the number of restaurant businesses is increasing. Wastewater caused by these restaurant activities will be a problem for the environment. Processing of restaurant wastewater can be done by biological treatment because it can reduce the organic content in wastewater. The biological processing process that can be used is the Moving Bed Biofilm Reactor (MBBR) system. The MBBR process in principle is biological growth using suspended and embedded cultures which are mixed in a reactor with aeration and moving media. This study aims to determine the performance of MBBR in reducing BOD, TOC and TSS in restaurant wastewater. The media used were Kaldness K3 and Bioball with various media compositions, namely 100% K3 Kaldness, 100% Bioball, 50% K3 Kaldness and 50% Bioball, 60% K3 Kaldness and 40% Bioball, 40% K3 Kaldness and 60% Bioball. The second variation is the sampling time, namely 3 hours, 6 hours, 9 hours, 12 hours, and 15 hours. Based on the results of this study indicate that the optimum MBBR reactor capability is with a composition of 100% K3 Kaldness at a sampling time of 15 hours. The reactor can reduce TOC by 97.84% and for the decrease in TSS by 76.84%.
