Abstract

Air limbah industri makanan berkontribusi signifikan terhadap pencemaran lingkungan. Air limbah, terutama dari mencuci bahan baku, kegiatan memasak dan mencuci peralatan produksi. Polutan utama dalam air limbah adalah senyawa organik seperti karbohidrat, minyak, lemak, dan protein. PT. EBI adalah salah satu produsen makanan cepat saji, yang berlokasi di Ciracas, Jarkata Timur. Untuk mengolah air limbah mereka, pada awalnya PT. EBI menggunakan WWTP Lumpur Aktif. Semakin meningkat kegiatan produksinya, jumlah air limbah yang dihasilkan juga bertambah. Akibatnya, IPAL yang ada tidak dapat mengolah air limbah, ditandai dengan penurunan kualitas produk yang diproses IPAL. Untuk mengatasi masalah ini, PT. EBI melakukan renovasi IPAL, yaitu mengganti IPAL Lumpur Aktif dengan IPA Biofiler. Inovasi ini memberikan hasil yang sangat positif. Kualitas produk olahan WWTP jauh lebih baik dan Standar Kualitas selalu terpenuhi. Hasil WWTP baru, konsentrasi polutan TSS menurun dari 340 mg / l menjadi 20 mg / l atau efisiensi pengobatan mencapai 94%, konsentrasi KMnO4 menurun dari 883 mg / l menjadi 50 mg / l (efisiensi, 94%), konsentrasi COD turun dari 1.654 mg / l menjadi 75 mg / l (efisiensi, 95%) dan konsentrasi BOD5 turun dari 392 mg / l menjadi 35 mg / l (efisiensi, 91%). Hasil ini menunjukkan bahwa IPAL Biofilter juga sangat efektif digunakan untuk mengolah air limbah industri makanan.Kata kunci: Air limbah indutri makanan, instalasi pengolahan air limbah, biofilter, Baku Mutu Air Limbah

Abstract

Determination of polychlorinated biphenyls (PCBs) and polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDDs/Fs) in water samples from Jabodetabek urban area was conducted. In the results, a unique pattern were found interestingly in Ciliwung river, Pluit, Jakarta, where decachlorinated biphenyl (PCB IUPAC #209), and dichlorinated biphenyl (PCB IUPAC #11) were detected at relatively high concentrations as 406.77 ng/L and 6.38 ng/L, respectively. This congener pattern is different with commercial PCB mixtures, such as arochlor, kanechlor, or chlophen. Octachlorinated dibenzo-p-furan (OCDF) was also detected at a significant concentration in this water as 3.10 ng/L. Decachlorinated biphenyl (PCB IUPAC #209) and OCDF were associated with industrial by-products. Meanwhile, dichlorinated biphenyl (PCB IUPAC #11) was associated with colour pigment which widely used in consumer goods, such as paint and printed ink. Thus, PCBs and PCDD/Fs contamination might have arisen from industrial by-products where various industries located near sampling point. Keywords: polychlorinated biphenyls (PCBs), polychlorinated dibenzodioxins /polychlorinated dibenzo-p-furans (PCDDs/Fs), waters, Jabodetabek, industrial by-products.

Abstract

A biological denitrification using autotrophic bacteria in batch suspension runs was investigated to clarify the effect of pH on denitrification rate. Elemental sulfur was employed as an electron donor. The culture of autotrophic bacteria was obtained from activated sludge by acclimatization. The effect of pH on denitrification rate could be expressed by bell-shape equation with optimum pH of 7,07. However at a pH range of 5,5 to 8,0, the denitrification rate significantly fastl. Therefore, the application of the denitrification of wastewater using autotrophic bacteria is suggested running well although without controlling pH.  Kata kunci : Denitrification, nitrate, autotrophic bacteria, elemental sulfur, pH.

Abstract

Effect of nitrite on denitrification of synthetic wastewater using autotrophic bacteria was evaluated in both batch suspension and continuous packed column runs. Emphasis was placed to clarify the minimum concentrations of nitrite and nitrous acid that inhibit the denitrification rates. Batch suspension runs were conducted by mixing acclimatized denitrification sludge and synthetic wastewater in an Erlenmeyer flask. In continuous runs, denitrification sludge was loaded to a column packed with sulfur and limestone. The nitrite inhibition could be explained satisfactorily by substrate non-competitive inhibition model. The minimum concentration of nitrite which inhibits the nitrate and nitrite removal rate lowered with decreasing pH. In suspension runs, the minimum concentration of nitrous acid which inhibited the nitrite removal rate was 0.043 g-N/m3, while the nitrate removal rates was inhibited below 0.012 g-N/m3.  Both in suspension and continuous packed column runs, nitrate removal was more sensitive against nitrite increase compared with nitrite removal. The minimum concentration of nitrite which inhibited nitrate removal rate in continuous packed column runs was lower than that in suspension runs.  Keywords:Autotrophic bacteria, denitrification, inhibition, nitrite, sulfur

Abstract

An autotrophic denitrification system was developed for treatment wastewater from steel industry. The aim was to evaluate the kinetics and capability of the system in reducing nitrate content in such industrial wastewater. The experiments were conducted in batch suspension and continuous runs. The denitrification kinetics in suspension runs obeys first order reaction with the rate constant k1 and k2 were determined to be 0.014 and 0.004 g-N/m3.d, respectively. The continuous runs used a column packed with mixture of granular sulfur and limestone. The microbes of Thiobacillus denitrificans were attached on the surface of granular sulfur in the form of biofilm. The biofilm thickness was investigated to be approximately 40 μm. The denitrification kinetics in the packed column obeys half-order reaction with the rate constant k of 0.172 g-N1/2.m1/2/(kg-S.d). The lower denitrification extent of industrial wastewater compared with the synthetic wastewater might be due to the lack of alkalinity. Keywords: Autotrophic denitrification, sulfur, packed column, thiobacillus denitrificans.
