Abstract

ABSTRAKLindi  adalah cairan yang ditimbulkan oleh sampah akibat masuknya air eksternal yang dapat melarutkan materi-materi terlarut, termasuk materi-materi organik hasil dekomposisi secara biologi. Lindi dari sebuah landfill (TPA) mengandung zat organik dan anorganik dalam konsentrasi yang tinggi. Dengan adanya gaya gravitasi maka lindi yang terbentuk akan bergerak ke dasar landfill (TPA) akan masuk ke dalam tanah dengan membawa bahan cemaran baik material tersuspensi maupun material terlarut yang dapat mencemari air tanah. Salah satu proses pengolahan lindi adalah dengan menggunakan reagen Fenton dan adsorpsi yang termasuk dalam teknologi Advanced Oxidation Processes (AOPs). AOPs didasarkan pada pembentukan spesies yang sangat reaktif seperti radikal hidroksil (OH•) yang efektif untuk menurunkan COD, BOD dan TSS. Penelitian ini bertujuan untuk mengolah lindi menggunakan reagen Fenton dan adsorpsi serta mempelajari rasio molar Reagen Fenton dan  waktu pengadukan terhadap penurunan COD, BOD dan TSS. Pada penelitian ini lindi diolah selama 30-120 menit. Kondisi optimum dicapai pada rasio molar 1:200, waktu pengadukan 120 menit, dan adsorpsi menggunakan karbon aktif selama 120 menit dimana penurunan COD, BOD dan TSS maksimum yang dicapai berturut-turut 95%, 95% dan 92% dengan nilai konsentrasi akhir 96 mg/L, 25,5 mg/L% dan 90 mg/L.Kata Kunci: Lindi, Reagen Fenton, AOPs, COD, BOD, TSS ABSTRACTLeachate is a liquid generated by waste due to the entry of external water that can dissolve dissolved materials, including decomposition of organic matter biologically. Leachate from a landfill (TPA) contains organic and inorganic substances in high concentrations. by gravitational force, the leachate formed will move to the bottom of the landfill (TPA) and will enter the soil by carrying contaminated material, both suspended material and dissolved material that can pollute ground water. One of the leachate treatment processes is using Fenton reagent and adsorption. Fenton method included in Advanced Oxidation Processes (AOPs) technology. AOPs are based on the formation of highly reactive species such as hydroxyl radicals (OH•) which are effective for reducing COD and BOD. This study aims to treat leachate by using Fenton reagent and adsorption. The effect of reagent Fenton molar ratio and stirring time on degradation of COD, BOD and TSS were also investigated. In this study leachate was processed for 30-120 minutes. the optimum conditions were achieved at a molar ratio of 1: 200, stirring time of 120 minutes, and adsorption using 120 minutes of activated carbon where the maximum decrease in COD, BOD and TSS achieved was 95%, 95% and 92% with a final concentration of 96 mg/L, 25.5 mg/ L and 90 mg/ L.Keywords : Leachate, Fenton Reagent, AOPs, COD, BOD, TSS

Abstract

The number of laundry industry has been increasing rapidly which influences the amount of detergent usage in the washing process. Generally the laundry industries dump their wastewater directly to environment without any treatment. Phosphate contained in detergent shall accumulate in the environment then finally would cause eutrofication where the water body becomes rich of dissolved nutrient which effects the dissolved oxygen contained in water body. One of wastewater treatment methods is adsorption. Two different kinds of adsorbents were applied in this investigation namely activated carbon and natural zeolite. Synthetic laundry wastewater was used in order to control the phosphate concentration. The objective of this experiment was to study the removal of phosphate concentration of each adsorbent filled in adsorption column by using circulation method. The column has 1 inch of diameter, 50 cm of height, and 50 ml/minute of flowrate. The concentration of phosphate was varied between 2-8 mg/l whereas the adsorbent height in the column was varied between the ranges of 10-40 cm. The size of both adsorbents was 10 mesh. It was found that the natural zeolite was superior to remove the phosphate compared to activated carbon. The highest phosphate removal of 90% was obtained by using 40 cm of natural zeolite height in the adsorption column when make use the phosphate concentration of 2 mg/l.

Abstract

The anaerobic ammonium oxidation (anammox) as a new biological approach for nitrogen removal has been considered to be more cost-effective compared with the combination of nitrification and denitrification process. However, the anammox bioreactors are mostly explored at high temperature (>300C) in which temperature controlling system is fully required. This research was intended to develop and to apply anammox process for high nitrogen concentration removal at ambient temperature used for treating wastewater in tropical countries. An up-flow biofilm column reactor, which the upper part constructed with a porous polyester non-woven fabric material as a carrier to attach the anammox bacteria was operated without heating system. A maximum nitrogen removal rate (NRR) of 1.05 kg-N m3 d-1 was reached in the operation days of 178 with a Total Nitrogen (TN) removal efficiency of 74%. This showed the biofilm column anammox reactor was successfully applied to moderate high nitrogen removal from synthetic wastewater at moderately low temperature.

Abstract

The surface area of a photocatalyst is an important factor that effect decomposition process of colored wastewater. Increasing the catalyst particle surface area will increase the UV light absorbed thus enhance the photacatalysis process. Bulk TiO2 will have the higher surface area if it is made in the nano size. As a photocatalyst, nanoparticle of TiO2 is more efficient than bulk of TiO2. The nanoparticle of TiO2 can be made in various ways, for example by simple heating method. In this study, the synthesis of nanoparticle TiO2 was investigated by optimize the amount of polyethilene glycol (PEG 200) used and the annealing temperature. The amount of PEG 200 was varied between 6-18 ml. Moreover, the annealing temperature was varied in the range of 600-700oC. After synthesizing, the nanoparticles of TiO2 then characterize by using scanning electron microscope (SEM) to observe the morphology, and by using the X-ray difraction (XRD) to find the crystal structure and the particle size. Based on the characterization, it was found that the smallest nanoparticle of TiO2 have a 29 nm in size was produced by using the 12 ml of PEG at the annealing temperature of 600oC.

Abstract

The pulp and paper industry wastewater has not met the environmental uality standards set by the government so it may causes pollution to the environment; therefore, it is necessary to find a better wastewater treatment. The problem of this study is how to find the wastewater treatment alternative in order to get a more effective and efficient treatment. Fenton reagents are H2O2 compounds (hydrogen peroxide) with iron catalysts and is one of the Advance Oxidations Process (AOPs) methods, which can be used as an alternative to process wastewater from the pulp and paper industry. In this study, the ratio of Fenton reagent molar concentration, temperature, and stirring time were varied, with stirring speed of 300 rpm, Fenton reagent volume of 25 mL, and pH set at 3. The visible parameters in this study were COD and TSS degradation. From this study, the best ratio of Fenton reagent is 1:2000, where this ratio can reduce the COD from 1002 mg/L to 176.05 mg/L and the TSS from 125 mg/L to 49.3 mg/L. This value has met the environmental quality standards for the pulp and paper industry set by the Indonesian government.
