Perairan Silugonggo merupakan area pemukiman warga dengan banyak aktivitas perikanan dan kelautan seperti: pertambakan, industri perikanan dan merupakan alur pelayaran. Tingginya aktivitas pemukiman dan industri akan menghasilkan limbah organik dalam jumlah besar. Bahan organik yang melimpah dapat menimbulkan pencemaran lingkungan. Penelitian ini bertujuan untuk mengetahui kandungan bahan organik di perairan sungai Silugonggo, Kecamatan Juwana, Kabupaten Pati. Kandungan bahan organik diketahui melalui analisis parameter TOM (Total Organic Matter), BOD5 (Biochemical Oxygen Demand) dan COD (Chemical Oxygen Demand). Pengambilan sampel dilaksanakan pada tanggal 20 Desember 2019 dan 20 Januari 2020. Metode yang digunakan pada penelitian ini menggunakan metode kasus dengan pengamatan secara langsung di lapangan dan penentuan lokasi penelitian menggunakan metode purposive sampling. Hasil pengukuran parameter penelitian dianalisis menggunakan analisis ragam. Hasil penelitian menunjukkan bahwa nilai TOM sebesar 8,11 – 11,9 mg/L. Hasil pengukuran parameter (a) BOD5 sebesar 8,07 – 24,66 mg/L dan (b) COD sebesar 26,04 – 79,21 mg/L, hasil tersebut berada di bawah baku mutu yang ditetapkan menurut Keputusan Menteri Lingkungan Hidup No. 51 Tahun 2004 tentang Baku Mutu Air Limbah. Tingginya nilai TOM dikarenakan banyaknya masukan limbah bahan organik dari aktivitas di perairan sungai Silugonggo, seperti: pertambakan, industri perikanan, dan alur pelayaran. Silugonggo waters is a residential area with many fishery and marine activities such as: aquaculture, fishing industry and shipping lanes. High residential and industrial activities will produce large amounts of organic waste. Abundant organic matter can cause environmental pollution. This study aims to determine the content of organic matter in the waters of the Silugonggo River, Juwana District, Pati Regency. The content of organic matter is known through parameter analysis of TOM (Total Organic Matter), BOD5 (Biochemical Oxygen Demand) and COD (Chemical Oxygen Demand). Sampling was carried out on December 20, 2019 and January 20, 2020. The method used in this study used the method of direct observation in the field and the date of the research location using the purposive sampling method. The results of the measurement of research parameters were analyzed using analysis of variance. The results showed that the TOM value was 8.11–11.9 mg/L. Parameter measurement results (a) BOD5 of 8.07–24.66 mg/L and (b) COD of 26.04–79.21 mg/L, these results are below the quality standard stipulated according to the Decree of the Minister of the Environment No. 51 of 2004 concerning Wastewater Quality Standards. The high value of TOM is due to the large number of inputs of organic matter from activities in the waters of the Silugonggo river, such as: aquaculture, fishing industry, and shipping lanes.

AbstractUsuma Dam is the major source of potable water in the Federal Capital Territory, Abuja, Nigeria. The physicochemical properties of water and sediment of the dam was assessed in this study to determine its quality. Electrical conductivity, pH, nitrate, phosphate, total dissolved solids, total suspended solids, turbidity, dissolved oxygen, biochemical oxygen demand, chemical oxygen demand, chloride, total hardness, phosphate, nitrate and sulfate were determined in the water samples. Total organic matter, total organic carbon and particle size were among the parameters analyzed in sediments. The parameters were within recommended limits except for biochemical oxygen demand and chemical oxygen demand which were more than the recommended limit of 10 mg/L and 30 mg/L respectively. The total organic matter and the total organic carbon in the sediment samples were between 1.56±0.27 – 2.85±0.20 % and 0.13±0.03 – 0.96±0.03 % respectively. The particle size was in the following order: sand > silt > clay. The results of this study confirmed the presence of high organic and inorganic matter in the dam from non-point pollution sources occasioned by storm water from poorly planned settlements around the dam and runoffs from agricultural practices.

In order to study the simultaneous removal of nitrate and organic matter from a dairy effluent containing 670 mg∙L-1 of nitrate (NO3--N) and 5 760 mg∙L-1 of dissolved chemical oxygen demand (CODd), denitrification in a laboratory scale bioreactor consisting of an immersed bacterial bed colonized by an heterotrophic denitrifying flora (HDF) selected for NO3- reduction, COD consumption and adapted to grow on an effluent produced by a dairy industry was investigated. The obtained results indicated that at the optimal conditions of temperature (30°C), pH (7), COD/NO3--N ratio (5), the operation lasted 108h with total reduction of nitrate in 72h, no nitrite accumulation, and 92% of soluble COD removal in 96h. This indicates that the biodenitrification was accompanied with a high efficiency of matter organic removal as an electron donor, and thereby satisfies the applicable standards.

This study was designed to investigate the fungi associated with palm oil mill effluent (POME) in Gulur village of Tumkur. Biodegradation of palm oil mill effluents was conducted to measure the discarded POME based on physicochemical quality. The fungi that were isolated are Aspergillusniger, A. flavus, A. fumigatus, A. ochraceus, Rhizopussp, Peniciliumsp and Trichodermavirde. The autoclaved and unautoclaved raw POME samples were incubated for 7 days and the activities of the fungi were observed each for 12 hours. The supernatants of the digested POME were investigated for the removal of chemical oxygen demand (COD), color (ADMI), and biochemical oxygen demand (BOD) at the end of each digestion cycle. The results showed that the unautoclaved raw POME sample degraded better than the inoculated POME sample and this suggests that the microorganisms that are indigenous in the POME are more effective than the introduced micro-organisms. This result, however, indicates the prospect of isolating indigenous microorganisms in the POME for effective biodegradation of POME. Moreover, the effective treatment of POME yields useful products such as reduction of BOD, COD, and color.

Abstract Biological treatment methods are used to remove organic and some inorganic substances from wastewater using the simplest organisms that use these substances for nutrition, breaking them down using cellular processes. The article deals with the aerobic, anaerobic and anoxic stages of biological wastewater treatment. Their differences are explained and the best way to use biological processes is analyzed according to the type of industry/production. At wastewater treatment plants, anaerobic treatment is often used at first to remove a significant part of organic substances from wastewater before sending them for further aerobic treatment. Aerobic treatment is effective for various types of wastewater, especially with lower biochemical oxygen demand (BOD) and chemical oxygen demand (COD). A comparative analysis of wastewater composition from food, oil and gas processing, pharmaceutical and pulp and paper industries was carried out. In the presence of organic compounds, the technology is chosen depending on the total organic matter content or the total COD content, which characterizes the total organic matter in water. A combination of anaerobic and aerobic methods is possible, if a discharge into the sewer system or into water bodies is required. The grounds for the application of biological wastewater treatment of these industries are given.
