The efficiency of two possible intensification methods of activated sludge waste water treatment (pure oxygen activation and activated carbon addition) were compared. Experiments were carried out in laboratory scale equipment with variable reactor volume (maximum capacity 20,0 dm3, settling tank vol. 15 dm3). In order to detect even minor differences, we operated completely identical units in parallel runs, with one representing a traditional system as reference. A model sewage of industrial character, diluted milk, was used as influent and in the course of activated carbon intensification experiments an anion-active detergent was added as a poorly biodegradable model material to be removed mainly by adsorption. Reactor loads were gradually increased - from low values to overloading - by decreasing the dilution of milk or by reducing reactor volume. The effects of different intensification methods on the effluent pollution level (COD value and anion-active detergent content) and on the settling properties of sludge were examined as a function of loading. The efficiency of both intensification methods was found to be increasing with increasing loading. Comparison of the two systems showed activated carbon intensification to be more efficient in the removal of soluble COD and extremely useful in the elimination of a poorly biodegradable material.

Domestic Wastewater Treatment

ABSTRAK Di Indonesia, operasional penambangan batubara umumnya melibatkan tenaga kerja dengan jumlah yang besar. Kondisi ini memberikan tantangan tersendiri dalam pengelolaan dampak lingkungan yang berpotensi timbul dari aktivitas manusia. Salah satu potensi tersebut yakni air limbah domestik. Air limbah domestik merupakan air limbah yang berasal dari aktivitas hidup sehari-hari manusia yang berhubungan dengan pemakaian air. Di area operasional pertambangan, air limbah domestik dapat timbul dari area pemukiman karyawan dan perkantoran. Karena potensi dampaknya terhadap lingkungan, air limbah domestik harus diolah sebelum dialirkan ke badan air penerima. Sejak tahun 1990an, diawal operasi penambangan, Kaltim Prima Coal (KPC) telah membangun dan mengoperasiokan Instalasi Pengolahan Air Limbah Domestik (IPALD) untuk mengolah air limbah domestik yang bersumber dari pemukiman karyawan dan perkantoran. Terdapat 12 IPALD dengan teknologi lumpur aktif yang beroperasi di area KPC. Lumpur aktif merupakan salah satu teknologi pengolahan air limbah domestik dengan memanfaatkan peran bakteri aerob untuk mendegradasi material organik yang terkandung didalam air limbah domestik. Makalah ini disajikan untuk mendeskripsikan performa teknologi lumpur aktif yang digunakan dalam IPALD KPC dan tantangan yang dihadapi dalam pengoperasiannya. Salah satu tantangan yang dihadapi yakni pemenuhan baku mutu yang tertuang dalam Keputusan Menteri Lingkungan Hidup dan Kehutanan No. P. 68 Tahun 2016 tentang Baku Mutu Air Limbah Domestik. Baku mutu terbaru mengatur konsentrasi efluen IPALD lebih ketat dari sebelumnya dan terdapat paramater baru, diantaranya amoniak yang memerlukan perhatian dalam pengoperasian IPALD. Kata kunci: air limbah domestik, lumpur aktif, ipald  ABSTRACT In Indonesia, coal mining operations generally involve a huge number of workers. This condition causes its own challenges in managing environmental impacts that potentially generated from human activities. One of them is domestic wastewater. Domestic waste water is waste water that comes from activities of daily living of humans related to water usage. In mining operations, domestic wastewater is generated from office and residential areas. Because of the potential impact on the environment, domestic wastewater must be treated before flowing to natural water bodies. Since the beginning of mining operations in 1990s, PT Kaltim Prima Coal has been building and operating Domestic Wastewater Treatment Plant (IPALD) to treat domestic wastewater resulting from offices and residential areas. There are 12 IPALDs with activated sludge technology operating in the KPC area. Active sludge is one of the domestic wastewater treatment technologies by utilizing the role of aerobic bacteria to degrade organic material contained in domestic wastewater. This paper is presented to describe the performance of activated sludge technology used in the KPC’s IPALD and the challenges faced in its operation. One of the challenges faced is the fulfillment of water quality standards in Minister of Environment and Forestry Decree No. P. 68 of 2016 concerning Domestic Wastewater Quality Standards. The latest quality standards regulate the effluent concentration of IPALD more stringent than before and there are new parameters, including ammonia which requires attention in the operation of IPALD. Keywords: domestic waste water, activated sludge, ipald

ABSTRAK Air limbah domestik merupakan produk hasil aktivitas manusia setiap hari yang perlu dilakukan pengolahan agar keberadaannya tidak mencemari lingkungan dan mengganggu kesehatan manusia. Air limbah yang dihasilkan dari kontrakan X cukup mengganggu estetika karena warnanya yang keruh dan berbau tidak sedap, sehingga perlu dilakukan pengolahan. Penelitian ini bertujuan untuk mengkaji efektivitas hidroponik tanaman dengan filter karbon aktif ampas kopi dalam menurunkan polutan limbah greywater domestik. Tahapan penelitian ini meliputi aklimatisasi, RFT, pengujian parameter polutan dan analisa data. Konsentrasi limbah optimum yang tidak menimbulkan kematian pada tanaman sebesar 40% v/v. Hasil pengujian parameter selama tujuh hari didapatkan efektivitas penurunan polutan BOD sebesar 80.65%, COD sebesar 70.59%, TSS sebesar 79,17%, TDS sebesar -1,82%, fosfat sebesar -62,22% dan detergen sebesar -93,33% dan pH sebesar -0,75%. Artinya penelitian ini efektif untuk menurunkan polutan BOD, COD dan TSS, namun tidak efektif untuk menurunkan polutan TDS, fosfat dan detergen. Penelitian ini perlu ditindaklanjuti dengan mengkaji efektifitas penurunan polutan NH3 dan total coliform yang terkandung pada limbah domestik. ABSTRACT Household wastewater is a product of daily human activities that need to be treated so that does not pollute the environment and disturbing human health. The waste water generated from the rented house X is quite disturbing aesthetics because of the cloudy warning and bad odor, so it needs to be treated. This study aims to examine the hydroponic authority of plants with activated carbon coffee grounds filters in reducing household waste pollution. The stages of this research include acclimatization, RFT, testing of pollutant parameters and data analysis. The optimal concentration of waste which does not cause death in plants is 40% v / v. The parameter testing result for seven days showed the effectiveness of reducing BOD pollutants by 80.65%, COD 70.59%, TSS 79.17%, TDS -1.82%, phosphate -62.22% and detergent - 93.33% and pH -0.75%. The research is effective in reducing BOD, COD and TSS pollutants, but not effective for reducing TDS pollutants, phosphates and detergents. This research needs to be followed up by examining the effectiveness of reducing NH3 and total coliform contaminants which is contained in domestic waste.

Toxic Organic Compounds

The addition of powdered activated carbon (PAC) to activated sludge treatment systems to enhance removal of specific toxic organic compounds from wastewater was evaluated. Nine organic compounds encompassing a range of solubility, volatility, biodegradability, and adsorptive properties were studied. Kate and equilibrium investigations were conducted to quantify the removal mechanisms of volatilization, biodegradation, biosorption, and carbon adsorption. Results from steady-state bioreactor studies showed that the addition of less than 100 mg/ℓ powdered activated carbon to the influent did not enhance the removal of the biodegradable target compounds investigated: benzene, toluene, ethylbenzene, o-xylene, chlorobenzene, and nitrobenzene. Significantly improved removals of the poorly degradable and non-biodegradable compounds 1,2-dichlorobenzene, 1,2,4-trichlorobenzene, and lindane occurred at influent powdered carbon concentrations in the 12.5 to 25 mg/ℓ range. Influent powdered carbon concentrations of 100 mg/ℓ effected overall removals of greater than 90%. The addition of powdered activated carbon not only reduced effluent concentrations but also reduced the amounts of the volatile compounds stripped to the atmosphere.

In the calculations customarily used to dimension nitrification and denitrification plants in the Federal Republic of Germany, solids in the influent of the biological stage represent a significant output variable. Numerous modified methods based on nationally and internationally standardized analysis procedures are available to determine solids concentrations in waste-water. Tests showed that different values are measured depending on the method of analysis employed. Harmonization of the analysis procedure is advisable to ensure comparable conditions for the calculation of activated sludge tank volumes. The solids reaching a treatment plant originate from two main sources. Filterable materials are passed to the treatment plant via the preceding sewerage network with its industrial and commercial users, but are also carried by process water from sludge treatment. The influence of process water on wastewater composition is illustrated by reference to the Wuppertal-Buchenhofen treatment plant.
