Air lindi dari proses rembesan air sampah organik yang ada pada rumah kompos umumnya mengandung beban pencemar yang sukar terurai. Air lindi tersebut akan menyebabkan masalah terhadap lingkungan jika dibuang langsung ke badan air apabila tanpa adanya pengolahan. Penanganan beban pencemar ini dapat dilakukan dengan metode Advanced Oxidation Process (AOP). Salah satu dari metode AOP adalah FotoFenton. Penelitian ini bertujuan untuk mengetahui efisiensi pengolahan air lindi dengan metode fotofenton secara resirkulasi berdasarkan perbandingan molar H2O2:FeSO4 dan Debit aliran resirkulasi. Pada penelitian ini, parameter yang diamati meliputi TSS, COD, BOD, Total N, dan PO4. Pada penelitian batch yang dilakukan dengan 5 liter air lindi ditetapkan variabel perbandingan molar H2O2:FeSO4 dengan variasi 10:0,10, 10:0,15, 10:0,20, 10:0,25, dan 10:0,30 dan variabel Debit aliran resirkulasi dengan variasi debit 0,2, 0,25, 0,34, 0,4, dan 0,6 liter/detik. Selain secara batch, penelitian ini juga dilakukan percobaan kontinu fotofenton secara resirkulasi dengan variabel terbaik dari proses batch. Berdasarkan penelitian, efisiensi pengolahan TSS, COD, BOD, Total N, dan PO4 pada lindi menggunakan fotofenton secara resirkulasi masing-masing sebesar 91%, 87%, 70%, 65% dan 79% pada perbandingan molar 10:0,30 dengan debit aliran 0,6 liter /detik. Kata kunci: Air lindi, fosfat, fotofenton, limbah organik, total nitrogen, total suspended solid (TSS). Leachate from seepage process of organic waste water in compost houses generally contains pollutant load which is difficult to decompose. Leachate will cause problems to the environment if it is discharged directly into water if there is no treatment. The handling of these pollutants can be done by the Advanced Oxidation Process (AOP) method. One of the AOP methods is PhotoFenton. This study aims to determine the efficiency of leachate water treatment with the photofenton method by recirculation based on H2O2: FeSO4 molar ratio and recirculation flow discharge. In this study, the parameters observed included TSS, COD, BOD, Total N, and PO4. In a batch study conducted with 5 liters of leachate water, the molar ratio variables of H2O2: FeSO4 were determined with variations of 10: 0.10, 10: 0.15, 10: 0.20, 10: 0.25, and 10: 0.30 and variable discharge of recirculation flow with discharge variations of 0,2, 0,25, 0,34, 0,4, and 0,6 liter / second.

Tofu industry produces the waste that contains a lot of organic substances. The waste is discharged into the environment without any treatment process, it will cause the environmental pollution. In Indonesia, tofu industries (the small-scale industry) mostly do not treat their waste due to the problem of the high cost treatment process. The purpose of this research is to know the effective and economically reasonable that can be used by tofu producers to process tofu waste, especially liquid waste so not damage the environment. Water treatment process using bacterial from waste water as medium seems promising to develop since it does need any bacteria starter or other media like glucose. The other reason is wastewater from food processing is more suitable for microorganism cultivation because its effluent contains significant beneficial nutrient and less of toxic compounds and harmful substances that interface with the growth of microorganism in same condition (pH and Temperature) in Acclimatization process can reach 83.2% after 7 days of treatment. After the detention time (18 hours) the results of COD number also greatly decrease with 2.5 hours recirculation at 12 L/min air and pH 3.7 and 4.5 it can reach 85% and 86% of removal COD.

Water from cattle farming operations that is not properly managed and discharged directly into the environment can cause unpleasant odors and increase the risk of contamination of surrounding water bodies. The purpose of this study was to determine an effective management system in solving odor problems and the risk of contamination of water bodies. The method in this research includes the design of a management system and laboratory-scale processing experiments involving the oxidation pond as the processing unit. The cattle farm liquid waste management system consists of 3 stages, namely pre-treatment, primary treatment, and secondary treatment, where there is a processing unit (oxidation pond) for secondary treatment. Wastewater is treated in the oxidation pond with a variation of the injected oxygen discharge of 6 L / minute, 8 L / minute, and 11 L / minute with residence time during the calculation time according to EPA / 600 / R-11/008 of 2011 (respectively 0.256 days, 0.1356 days, 0.1096 days), 3 days, 7 days, and 14 days were equipped with control of oxidation-reduction potential (ORP) values. The parameters observed were odor, Biochemical Oxygen Demand (BOD) and Total Ammonia (NH3-N). Where the wastewater after the treatment process is yellowish with low turbidity and has no smell. While the test results after the study showed that the average BOD level had met the quality standard. With the highest final BOD level was 152 mg / L and the lowest was 98 mg / L. Meanwhile, the highest total ammonia levels after research were 0.0088 mg / L and the lowest was 0.00032 mg / L. Management with an oxidation pond as a processing unit is effective in overcoming odor problems and reducing levels of BOD and ammonia pollutants.

Ground Water as an alternative to clean water is often found to contain iron (Fe) and (Mn). The content of Fe and Mn causes a yellow-brown color and leaves a yellow stain on the fabric. Fe content can cause health problems such as nausea when consumed, intestinal wall damage and irritation to the eyes and skin. Meanwhile, Mn content above the quality standard can cause disturbances in the vascular vessels, heart and nervous system. This well water can be treated in several ways, one of which is aeration. Aeration is the process of adding air to water through contact between water and air. There are several types of aerators, one of which is the Tray aerator. The Tray aerator is aerated with a vertical Tray arrangement. The water will pass through the perforated Tray level and will be caught at the bottom. To increase the efficiency of reducing Fe and Mn levels, it can be done by adding Kaolin media and activated carbon. The effect of aeration time is directly proportional to the decrease in Fe and Mn levels. The longer the aeration time, the more significant the decrease in Fe and Mn levels. the contact time between water and gas becomes longer. As a result, the transfer of oxygen from the gas phase to the liquid phase can be maximized. The results of this study indicate that the addition of adsorbent media in Tray aerator variations affects the percent removal of Fe and Mn levels in well water. With the highest percentage removal of Fe was 86.09% with a result of 0.64 mg / l using 500 gr kaolin media for 90 minutes and the highest percentage of Mn removal was 88.70% with a yield of 0.26 mg / l in 90 minute
