“…Salah satu parameter kualitas air adalah Biochemical Oxygen Demand (BOD) yang menyatakan kebutuhan oksigen oleh mikroorganisme dalam penguraian zat organik. Hasil uji BOD merepresentasikan kandungan polutan organik yang terdapat dalam air (Raud, Tenno et al 2012). Berbagai sumber polutan menyebabkan menurunnya kualitas air.…”

“…Pada metode BOD konvensional dibutuhkan waktu selama 5 hari pada 20 o C, sehingga disebut BOD5. Hasil uji BOD5 merupakan representasi sebagian dari total BOD (Raud, Tenno et al 2012). Untuk proses oksidasi biokimiawi sempurna zat-zat organik dalam sampel air menurut konvensi dibutuhkan waktu selama 20 hari.…”

“…Sensor mikroba sudah lazim digunakan di negara-negara maju. Keunggulan sensor mikroba adalah waktu pengukuran yang lebih singkat dan hasil yang tidak jauh berbeda dengan metode konvensional (Raud, Tenno et al 2012). Mikroorganisme yang sudah dimanfaatkan untuk pengukuran BOD antara lain Clostridium butyricum (Karube, Matsunaga et al 2009), Arxula adeninivorans (Chan, Lehmann et al 2000), Bacillus polymyxa D-21 (Su, Huang et al 1986), Photobacterium phosphoreum (Hyun, Tamiya et al 1993), Bacillus subtilis dan Bacillus licheniformis 7B (Li, Tan et al 1994), yeast (SPT1 dan SPT2) (Trosok, Driscoll et al 2001), Trichosporon cutaneum (Suriyawattanakul, Surareungchai et al 2002), Escherichia coli (Sakaguchi, Kitagawa et al 2003), Saccharomyces cerevisiae (Nakamura, Suzuki et al 2007)…”

BOD biosensor applications actually increased along with the development of human needs and the progress of science and technology. But in general still predominantly for applications in the field of medical and environmental.A BOD biosensor based on khamir metabolism was developed in order to shorten the measurement time of BOD value for environmental monitoring. The developed biosensor was fabricated by immobilizing khamir on a thin film in agarose matrix with Nafion® acting as the membrane for ion exchange process. The khamir was harvested from the fermentation Rhodotorula mucilaginosa. The film was then attached to gold as the working electrodes. The BOD biosensor was calibrated by using a solution containing the equivalent amount of glucose a standard sample solution. Optimum condition was observed in a waiting measurement time of 20 min at an applied potential of 500 mV (vs. Ag/AgCl). For analysis of glucose, the response time was observed 20 minutes with detection limit 1 mg/l. Good linear range with oxygen standard solution was observed, R 2 0.99 and the estimation of measurement error of 2.45%. The observed BOD value by biosensor showed a good comparison with the conventional.

“…The highest COD strength of any liquid effluent derived from slaughterhouses has blood with a COD up to 375,000 mg/L [5,11]. Therefore, the efficacy of blood collection is a significant factor in the determination of the amount of BOD 5 and COD in the meat-processing wastewater [10].…”

“…Blood, solubilized fat, urine and faeces are the primary sources of BOD 5 and COD in meat-processing wastewaters. The meat industry has the potential to generate large quantities of solid wastes and wastewater with a BOD 5 as high as 8,000 mg/L or 10-20 kilograms per metric ton (kg/t) of slaughtered animal [10]. The highest COD strength of any liquid effluent derived from slaughterhouses has blood with a COD up to 375,000 mg/L [5,11].…”

A B S T R A C TThe emission of untreated or insufficiently treated wastewater is very common in developing countries and consequently has harmful effects on the environment. The aim of this study was to analyse 24 physico-chemical parameters in raw wastewater and effluent after tertiary treatment (denitrification and disinfection) derived from meat-processing plants in Serbia during four sampling campaigns conducted for one year. The biochemical oxygen demand (BOD 5 ) and chemical oxygen demand (COD) were measured at high concentrations up to 6,960 and 14,160 mg/L, respectively, indicating a large amount of uncollected blood, solubilized fat, urine and faeces in discharged wastewater. Required limits of emission in all samples according to the European and national legislation for most of the studied parameters were exceeded. According to the obtained results, there is an imperative need for pretreatment of wastewater from meat industry before discharging it into the sewer. The applied wastewater treatment improved the quality of water by reducing BOD 5 and COD values to 97.97 and 98.08%, respectively, while phosphorus removal efficiency varied from 15.29 to 68.48%.
