Abstract

Peat water treatment still has many obstacles, one of the alternatives that can be used to overcomethis obstacle is membrane technology and UV light variais. This study aims to determine the effect of UV rayson the flux and content of BOD, TSS, pH, Turbidity, Color and E.Coli Bacteria. This study used a combinedmethod, namely ultraviolet (UV) light poses using a UV Water Sterilizer, the filtration process using the KUF3 ultrafiltration membrane and the phytoremediation method with kiambang plants. The results of this studyshowed the highest removal rate of BOD in the filtration process with UV 6 watts at 90 minutes of filtrationtime with an efficiency of 94.71%. The color removal rate in the filtration process with UV is 6 watts at 90minutes of filtration time with an efficiency of 70.92%. Turbidity removal rate in the filtration process withUV 6 watts at 90 minutes filtration time with an efficiency of 99.97%%. The TSS removal rate in the filtrationprocess with UV is 6 watts at 90 minutes of filtration time with an efficiency of 47.77%. The pH removal ratein the filtration process with UV is 6 watts at 90 minutes of filtration time with an efficiency of 24.79%. Theelimination rate of E.coli bacteria in the filtration process with UV is 6 watts at 90 minutes of filtration timewith 100% efficiency

Abstract

The aim of this research is to develop membrane material and analyse the membrane performance in liquid waste management of CPO industry to separate suspended solids. Conventional waste treatment has not been able to reach the minimum regulatory standards that have been set. Land area constraints and waste management techniques are complex and produce large sludge volumes. Besides specifically for managing liquid organic waste, the difficulty of the process of degradation of waste due to the high quantity and content of contaminants that can reach up to 40,000-120,000 mg / l for COD. In this study composite membrane made by titanium dioxide in the membrane polyvinylidene fluoride was blend very well and suited to remove suspended solids in the wastewater. The optimization result obtained is the addition of TiO2 2% produce maximum flux with the value of 180 L / m2.hr and the percentage of 92% fitration. The results of the filtration process conditions were the total suspended solids (TSS) by 99.63% and ammonium nitrogen (NH3-N) by 92.82% is the ABFR process conditions at 2.25 ml / min, HRT at 276.93 min, MLSS concentration at 4.50 g / L, and the pH at 6.50. So it can be concluded that titanium dioxide resulted the minimise of average poresize and enhance the hydrophilicity of membrane that resulted the maximum flux of this process.

Abstract

Indonesia is an agrarian country with subtropical climate suitable for planting multicultural and one of those plants is sugar cane. Sugar cane is a raw material for producing sugar, where biomass waste has not been utilized appropriately. The amount of biomass waste was produced of 24-30% from sugar mills. Effective, efficient and environmentally friendly waste treatment technology is needed to utilize the waste into a renewable energy source using gasification methods. Gasification is a process to convert biomass waste to combustible gases (CO, CH4, and H2). This process is combustion with limited air supply (20% -40% stoichiometric air) to break long hydrocarbon chains into short hydrocarbons at high temperatures. This method requires an updraft gasifier furnace that is capable of being operated at high temperatures, which can convert biomass waste into syngas with high conversion. An updraft gasifier is a gasification furnace at temperature of 300-500oC and atmospheric pressure, also used air flow of 10-20 L / min and zeolite as catalyst. This research are devided into few steps, namely drying, crushing, separating, gasification process, The proximate and ultimate method was used to analyze the produced syngas. Proximate analysis is an analysis to measure the calorific value by using a calorimeter bomb, ash content used AAF furnace, and moist water content used a decator. Moreover, ultimate method was used to analyze CH4, H2, O2, N2, CO and CO2 compositions by using Gas Chromatography (GC). Firstly, sugarcane bagasse as the main raw material, were dried and chopped in 7 cm then it were put into the gasifier. The results showed that maximum syngas ratio of combustible gas (CO, H2 and CH4) and noncombustible gas (NGC) of 1.03 with added the zeolit of 200 gr and water of 40 ,L/min.
