Bioenergy Potential Based on Vinasse From Ethanol Industrial Waste to Green Energy Sustainability

The waste water from alcohol industry is called vinasse has a high organic content, with BOD5 = 109.038 mg / l, COD = 353.797 mg / l and TSS = 7200 mg / l, pH 4-5 with a temperature of around 40-50ºC. The current treatment of alcohol waste water, most still using facultative anaerobic technology with open ponds that are only covered with HDPE plastics. This technology produces less optimal biogas and has a weakness that is the hydraulic residence time (HRT) for long (40-50 days), wide land needs, low COD reduction efficiency as well as high risk of fire and leakage of biogas release high to trigger the occurrence of greenhouse gas and global warming effects. Development of technology with innovation reactor integration model Fixed Dome-Hybrid Anaerobic Filter aims to expand the contact area between the substrate and microbial with modification of the substrate flow system and the area of the filter and integrate with the gas accumulator. The design of this Fixed Dome-Hybrid Anaerobic filter integration model technology, has the advantage of producing optimal bioenergy with CH4 more than 50% content with decrease of COD more than 85% and hydraulic residence time of about 10 (ten) days, bioenergy result is renewable energy made from raw material vinasse from alcohol industrial waste which can be utilized for fuel substitution on the distillation process or boiler process of the industry in a sustainable and cleaner environment.

Tapioca Flour

Cassava (Manihot utilissima) is the main raw material of tapioca flour industry. The tapioca industry waste water still contains high enough BOD, COD, and cyanide, above the quality standard of industrial waste water. Photo-Fenton is one of the most effective alternative methods of degrading organic pollutants. This study aims to determine the effect of Photo-Fenton method on the degradation of organic pollutants such as COD and cyanide. For operating conditions of this study use the addition of concentrations of H2O2 and FeSO4.7H2O and different UV light intensity. The analysis of COD concentration using SNI method is spectrophotometric. From the research result, it is found that the concentration of COD and cyanide in tapioca waste can be reduced by using Photo-Fenton method. With initial COD content of 6000 mg/L and cyanide level of 0.67 mg/L. And in the operating conditions of the addition of 5 ml/l of H2O2, Fe2+ 1.25 mg/l, and light intensity of 200 lm, the highest COD and cyanide levels were found to be 900 mg/l for COD and 0.08 mg/l for cyanide. Final levels of COD up to 900 mg/l and cyanide concentrations up to 0.08 mg/l.

Fenton Reagent

Simulation of Colored Waste Water Treatment Using Photo Fenton in Continuous System Waste water from coffee processing was treated by the Photo Fenton method. Experiments were carried out in a 2 liter batch reactor equipped with ultraviolet lamp for 4 hours. The synthetic waste water was made by dissolving 300 mg instant coffee in 1 liter water. Reagents used are 700 ppm H2O2 prepared from 30 % H2O2, and 15 ppm FeSO4.7H2O. The experiment was carried out at pH= 3. Prior to treatment, the color of the waste water was brownish yellow. After adding the fenton reagent under UV light exposure, the color of waste water changed to pale yellow, and finally became colorless. Absorbance and Total Organic Carbon (TOC) of the sample were measured periodically. The kinetics of organic carbon degradation followed first order reaction towards the TOC concentration. Based batch experiment data, organic degradation was simulated for a single CSTR and four CSTRs in series. The single CSTR with a residence time of 1100 minutes can reduce the organic content from 108 ppm to 10.8 ppm, whereas for the serial CSTR reactors, the residence time was only 100 minutes in each reactor to get the same reduction percentage. Keywords: photo fenton, colored waste water, continuous, residence timeAbstrakPengolahan limbah cair industri pengolahan kopi dilakukan dengan metode Foto Fenton. Kajian menggunakan limbah sintetis berwarna coklat, mengandung kopi 300 ppm. Percobaan dilakukan dalam sebuah reaktor gelas dua liter yang dilengkapi dengan lampu ultra violet. Reagen yang digunakan adalah hidrogen peroksida dengan konsentrasi 700 ppm yang dibuat dari H2O2 30%, dan besi sulfat 15 ppm. Pengolahan limbah dilakukan pada pH=3. Dengan penambahan reagen fenton dan bantuan lampu ultra violet, warna limbah cair berubah secara perlahan dari coklat menjadi kuning dan akhirnya tidak berwarna. Perubahan absorbansi relatif zat warna, kandungan bahan organik total diukur terhadap waktu. Berdasarkan data percobaan secara batch, kinetika degradasi karbon mengikuti orde satu terhadap konsentrasi bahan organik total. Aplikasi untuk sistem kontinyu dibuat menggunakan model simulasi penurunan kandungan organik dalam sebuah reaktor berpengaduk dan 4 buah reaktor berpengaduk yang dihubungkan secara seri. Dengan laju alir umpan tetap, peningkatan volume reaktor akan memperbesar waktu tinggal reaktan dalam reaktor. Hasil simulasi reaktor tunggal menunjukkan bahwa semakin lama waktu tinggal maka semakin tinggi persentase penurunan bahan organik total. Untuk mendegradasi 90% kandungan organik dalam limbah, sebuah reaktor kontinyu seharusnya dirancang dengan waktu tinggal 1100 menit sedangkan empat buah reaktor dirancang dengan waktu tinggal 100 menit.Kata kunci: foto fenton, limbah cair berwarna, kontinyu, waktu tinggal

Anaerobic Filter

A laboratory-scale study was conducted on a two-stage fermentation reactor system and an upflow anaerobic filter system at several loading rates and hydraulic retention times. Feed substrate was wastewater from yeast production plant. The hydraulic residence time for first-stage fermentation reactor was 7 days and loading rate was in the range of 1.1-2.3 kg COD m−3d−1. The hydraulic residence time for second-stage fermentation reactor was 3.5 days and loading rate was 0.8-1.0 kg COD m−3d−1. Upflow anaerobic filter was operated at hydraulic retention time ranging from 5 to 2 days and loading rates ranging from 0.5 to 4.5 kg COD m−3 d−1. Despite shorter residence time, higher purification effects have been achieved for upflow anaerobic filter than for I-stage digestion reactor. For anaerobic upflow filter 61%-68% of COD reduction has been achieved at loading rates 3.5-4.0 kg COD m−3 d−1 and retention time of 2 days. For both systems in comparison the relationship between purification effects and volumetric organic load has been established. Amount of generated fermentation gas has been measured and composition of that gas has been analysed. Methane content in fermentation gas was in the range of 6l%-64%, hydrogen sulfide content was 0.5%-1.9%. Laboratory experiments were carried out at the temperature 33°C.

Removal Of Metal Ions

: Manuscript discussed about the role of polysaccharides and their derivatives in the removal of metal ions from industrial waste water. Quick modernization and industrialization increases the amount of various heavy metal ions in the environment. They can possess various disease in humans and also causes drastic environmental hazards. In this review the recent advancement for the adsorption of heavy metal ions from waste water by using different methods has been studied. Various natural polymers and their derivatives are act as effective adsorbents for the removal of heavy metal ions from the waste water released from the industries and the treated water released into the environment can decreases the chances of diseases in humans and environmental hazards. From the literature surveys it was concluded that the removal of heavy metal ions from the industrial waste water was important to decrease the environmental pollution and also diseases caused by the heavy metal ions. Graft copolymers were acts as most efficient adsorbent for the removal of heavy metal ions and most of these followed the pseudo first order and pseudo second order model of kinetics.
