Anaerobic Sludge Blanket

The results of pilot experiments on municipal wastewater treatment using advanced processes are described. The most important aims of this research were to achieve reductions in energy consumption, environmental impact, quantity of stabilized sludge produced, and area necessary for plant construction. The pilot plant, which was constructed in the environs of the Senigallia (AN, Italy) municipal wastewater treatment plant, had a capacity of 500 to 2500 population equivalents (p.e.). In the most attractive system, municipal wastewaters with a low organic concentration were first treated in an upflow anaerobic sludge blanket (UASB) bioreactor with a capacity of 336 m3. Part of the effluent from this process was then conveyed to an anoxic biological fluidized bed (with a volume of 8 m3 filled with 3 m3 of quartzite sand) for pre-denitrification, and then to an aerobic fixed bed (with random plastic media and a volume of 8m3) for nitrification. It was also possible to treat the municipal wastewaters using the anaerobic fluidized bed directly, after microscreening or primary sedimentation. The research undertaken was intended to verify the reliability of these processes at ambient temperatures and with variable wastewater concentrations. The preliminary results obtained for COD, BOD, and N removal from municipal wastewaters indicate that this system is quite an attractive treatment alternative, mainly due to its low sludge production and energy consumption. These results will enable accurate design criteria to be identified for the construction of more economic treatment plants on a larger scale.

Air limbah rumah tangga merupakan salah satu potensi sumber pencemaran lingkungan . Berdasarkan Laporan JICA , 1995 pencemaran lingkungan di Jabodetabek adalah 80 % disebabkan oleh air limbah rumah tangga . Untuk meminimalkan pencemaran lingkungan, air limbah harus diperlakukan sebelum dibuang ke sungai . Masalah yang sering muncul dalam pengelolaan limbah domestik adalah luas lahan terbatas dan dana yang ada untuk membangun fasilitas pengolahan air limbah dan juga biaya operasional yang tinggi . Untuk mengatasi masalah tersebut, perlu pengembangan biaya rendah teknologi pengolahan air limbah dengan efisiensi penyisihan yang tinggi , mudah dioperasikan dan juga harus kompak . Sebuah teknologi kombinasi Upflow Anaerobic Sludge Blanket ( UASB ) dan aliran bawah Hanging Sponge ( DHS ) merupakan pengolahan air limbah ekonomi , mudah dioperasikan dan memiliki efisiensi penyisihan tinggi yaitu 98 % untuk BOD dan 99,8 % untuk bakteri . Namun, untuk membangun fasilitas pengolahan air limbah dengan menggunakan UASB dan teknologi DHS , perlu studi kelayakan . Makalah ini menjelaskan studi kelayakan ekonomi dan sosial dari penerapan teknologi pengolahan air limbah UASB dan DHS di Kota Bogor . Dengan perhitungan manfaat dan rasio biaya ( BCR ) , hasilnya menunjukkan bahwa BCR 2.13 . Ini berarti proyek pengolahan air limbah UASB dan DHS di Kota Bogor adalah layak. Kata kunci : air limbah rumah tangga , anaerobik selimut lumpur, studi sosial ekonom  AbstractDomestic wastewater is one of the potential sources of environment pollution. Based on the JICA Report, 1995 the environmental pollution in Jabodetabek was 80% caused by the domestic wastewater. To minimize the environmental pollution, the wastewater have to be treated before discharge to river. Problem which often emerge in management of domestic waste is the limited land area and existing fund to built a wastewater treatment facility and also the high operating cost. To overcome these problems, it needs development of low cost wastewater treatment technology with high removal efficiency, easy to operate and also should be compact. A combination technology of Upflow Anaerobic Sludge Blanket (UASB) and Downflow Hanging Sponge (DHS) represents an economic wastewater treatment, easy to operate and has high removal efficiency that is 98% for BOD and 99,8% for bacterium. However, to build the wastewater treatment facility by using the UASB and DHS technology, it needs a feasibility study. This paper explains an economic and social feasibility study of application the UASB and DHS wastewater treatment technology at Bogor City. By the calculation of benefit and cost ratio (BCR), the result shows that the BCR is 2.13. It means the UASB and DHS wastewater treatment project at Bogor City was feasible.

Anaerobic Sludge Blanket

This study aims to present the time behavior of wastewater flow parameters, organic matter, biogas flow, biogas composition, and its relations, measured through online sensors, in a municipal wastewater treatment plant (WWTP) operating full-scale upflow anaerobic sludge blanket (UASB) reactors, installed in the south of Brazil. WWTP has online measurement devices to evaluate some physicochemical variables of the sewage and the biogas. The COD analyzer (UV– Vis probe), ultrasonic flow meter, biogas flow meter, and biogas composition analyzer were the equipment used. The monitoring occurred for two time periods each of 72 h and one time period for 48 h in the year 2018. Data were checked with descriptive statistics, data independence was checked through the autocorrelation Box– Ljung test, normality behavior was checked with several tests (Shapiro– Wilk, Kolmogorov–Smirnov, Lilliefors, Anderson–Darling, D’Agostino K2, and Chen–Shapiro), and Spearman’s correlation coefficient was used to evaluate the correlations among the parameters. The mean sewage flow was 345 ± 120 L.s-1; removed organic load was, in average, 48%; biogas quality values were 82.32% ± 3.62% v/v (CH4), 2.66% ± 1.19% v/v (CO2), and 3453 ± 1268 ppm (H2S); and the production per capita obtained was 4.51 ± 1.65 NL.hab-1.d-1. It was estimated an electric power generation of 3118.6 kWh.d-1, which is equivalent to an installed power of 130 KW. The behavior of removed organic load and biogas flow (Nm3.h-1), produced in the treatment plant, showed variable, periodic, and nonstationary time behavior.
