Abstract

Domestic wastewater contains high organic carbon and ammonium concentration which can be treated by moving bed biofilm process. It is a biologycal hybrid between attached and suspended growth process. The purposes of this research were to determine the removal percentage of organic carbon and ammonium concentration in domestic wastewater, and to investigate optimum hydraulic residence time. Experiment was carried out in a laboratory scale to study the combine anoxic and an aerobic reactor condition. The treatment process is preceeded by a 4-week seeding process continued with variation of hydraulic residence time. Based on these results, the removal percentage of COD for each hydraulic residence time of 12, 16, and 20 hours were 75,7%; 83,7%; and 91,0%, the removal percentage of ammonium were 79,4%; 91,0%; and 92,3%. The optimum hydraulic residence time in removing organic carbon and ammonium concentration domestic wastewater using anoxic aerobic MBB is 20 hours. This biological hybrid treatment can be an alternative to remove organic carbon and ammonium in domestic wastewater. Keyword: domestic wastewater, ammonium removal, organic carbon removal, moving bed biofilm reactor

Abstract

Saat ini PDAM Kota Surabaya mempunyai kapasitas pengolahan total sekitar 10.500 liter per detik yang terdiri dari beberapa instalasi yaitu IPA Karang Pilang I, IPA Karang Pilang II, IPA Karang Pilang III, IPA Ngagel I, IPA Ngagel II dan IPA Ngagel III. Kapasitas total instalasi pengolahan air Ngagel I sebesar 1800 liter per detik, dan Ngagel II sebesar 1000 liter per detik, sedangkan kapasitas instalsi pengolahan air Ngagel III sebesar 1.750 liter per detik. Air baku yang digunakan adalah air sungai yang diambil dari sungai Surabaya. Seiring pesatnya pertumbuhan pemukiman dan perkembangan sektor industri, mengakibatkan semakin tingginya tingkat pencemaran Sungai  Surabaya. Hal tersebut berpengaruh pada menurunnya kualitas air oleh polutan khususnya polutan organik dari limbah domestik maupun limbah industri. Akibatnya  Sungai Surabaya memiliki kualitas air baku yang kurang memenuhi ketentuan baku mutu yang dipersyaratkan sebagai air baku air minum. Untuk mengetahui kondisi tingkat pencemaran di dalam air sungai salah satu metoda yang banyak digunakan adalah dengan menentukan indeks pencemaran (IP). Penelitian ini bertujuan untuk mengetahui kondisi kualitas air baku di intake Ngagel serta menentukan tingkat pencemaran dengan menggunakan metoda indeks pencemaran. Penelitian ini dilakukan dengan menggunakan data sampling kualitas air di intake Ngagel yang dilakukan oleh PDAM dari tahun 2015 sampai dengan tahun 2017. Dengan menggunakan perhitungan Indeks Pencemaran (IP), dapat diketahui bahwa tingkat pencemaran air di Intake Ngagel tahun 2015 - 2017 tergolong dalam pencemaran sedang hingga pencemaran berat. Parameter yang paling potensial menyebabkan tingkat pencemaran tersebut adalah COD, BOD, Zat Organik serta konsentrasi oksigen terlarut (DO). Konsentrasi polutan organik dalam sungai tersebut telah melebihi baku mutu air kelas I berdasarkan PP No 82 tahun 2001, yakni untuk peruntukan air baku air minum. Dari tahun 2015 hingga 2016, terjadi peningkatan tingkat pencemaran, tetapi pada tahun 2017 tingkat cemaran cenderung sedikit mengalami penurunan dibandingkan dengan 2 (dua) tahun sebelumnya. Salah satu alternatif untuk meningkatkan kualitas air baku di Intake Ngagel yang yang diambil dari Sungai Surabaya adalah dengan menggunakan sistem biofilter.Dengan proses biofiltrasi konsentrasi polutan organik, amoniak, detergen, padatan tersuspensi, zat besi, mangan akan dapat diturunkan sehingga konsumsi bahan kimia khususnya koagulan dan khlor untuk pengolahan air minum menjadi berkurang. Dengan demikian biaya produksi pengolahan air juga akan menjadi berkurang. Dengan semakin rendahnya konsentrasi amoniak di dalam air baku, maka penggunaan khor juga akan semakin sedikit, sehingga kemungkinan terjadinya senyawa hasil samping khlorinasi misalnya trihalometan juga semakin kecil.Kata Kunci : Biofilter, IPA, Kualitas Air

Abstract

Contamination of rivers has reached an alarming level, especially in the rivers passing through major cities, agricultural areas and industrial areas. Among the contaminants that often appear dominant and very disturbing is the organic substance. The existence of high organic matter within the river water is often expressed in permanganate number that has passed the quality standard. River that contain high organic matter usually the water smell and the color is black, besides it can also cause disturbances in the water treatment process, which is an increasing use of coagulants, chlorine, activated carbon, and the emergence of substances that are not desired, and the quality of treatment results are unsatisfactory. Many ways to reduce the organic matter in river water, one of them is by using the biofilter honeycomb structure. The target of the reduction of organic substances is that the river water could be used as a raw drinking water quality standards or meet the category B, Regulation of Jakarta Governor Number 582, 1995. Raw water used for this study were taken from Krukut River which is the raw water for Regional Water Company PALYJA, Production Installation III Cilandak, South Jakarta and Cengkareng Drain river water, which is currently used as a source of raw water for PAM Taman Kota, West Jakarta using a biofilter reactor aerobic system, the capacity of 50 - 200 m3, Capasity of Blowers 300 l /min, Residence Time 6 hours up to 1 hour. Test results on the residence time of 1 hour, parameters pH, TSS, turbidity, organic substances, detergents, manganese, ammonia, nitrite, nitrate, can meet the standard, except for iron which still exceeds the standard. To improve the removal  efficiency of organic matter and iron, at the beginning of processing before entering into the drinking water treatment unit need to be added powder active carbon and an oxidizing agent with a sufficient dose. Keywords: Organic substances, biofilter, aerobic, honeycomb plastic media.

Abstract

Drinking water supply for public is big deals for the improvement of environmental and society health. An effort from the government to provide the drinking water supply is to provide a society based of drinking water treatment plant. Some obstacles that have come for the plant in remote areas are the difficulties of getting chemical material for the plant and the lack of energy supply. Drinking water treatment that use chemical materials has a big cost to provide the chemicals. Beside the high cost of treatment, the using of chemicals will harmful the drinking water, because it usually generates such carcinogenic materials. The biofiltration-ultrafiltration treatment is one of the best solutions to replace treatment plant that using chemicals. It has a low cost operation and is more safe than the water treatment that using chemicals. Generator-set (genset), a power generator that easy to get and operate, has uneconomical operation cost. By now, there were many studies proved that in remote areas, the using of Solar Power Plant is more economic than a genset. For those reasons, in this article is designed a solar powered 50 m3/Day drinking water treatment (biofiltration-ultrafiltration process). The result from the design is the solar power plant that can supply the treatment plant for 8 hours. Keywords: drinking water, solar power, genset, biofiltration, ultrafiltration.

Abstract

There are literally dozens of different types of biofilters used for wastewater treatment applications. While many have common features, some are fundamentally different from the rest. The purpose of this article is to educate the reader about the types of packings used for fixed film biofilters.The types of biofilters under discussion are filters that employ a non-moving surface area to provide a substrate for various bacteria to attach and grow. The substrate remains in place while the water flows through the system. The heart of these biofilters is the packing or media used to provide the surface area. The type of packing used strongly influences both the capital and operating costs of the biofilter. It is important to emphasize however, that the packing merely provides surface area for bacteria to colonize. It is the bacteria that do the actual work of the biofilter. In order for the bacteria to do their job effectively, the biofilter and packing design must provide an even distribution of nutrients and oxygen while removing dissolved and suspended waste products. Most biofilters utilize aerobic bacteria but it is also possible to design and operate anaerobic systems for special purposes. Various types of packings exist for fixed film biological filters. Each different type has advantages and disadvantages but in terms of overall cost and suitability, the structured packings are the best choice for commercial biofilter designs. Kata kunci : biofilter, media, pengolahan air limbah.

Abstract

To reduce the organic substance and ammonia in raw water hence raw water from river have to be processed by pretreatment prior to main processing unit. One of the alternatives is biological treatment using submerged biofilter which filled with honeycomb plastic supporting media. Research conducted by operating continuous flow biofilter reactor wich filled with honeycomb plastic supporting media. The size of biofilter reactor is 59 cm x 30 cm x 210 cm, with total volume 371.7 litres.  The research was conducting by continuous operation under condition 4 hours, 3 hours, 2 hours and 1 hour retention time. The result of experiment shows that within the biofilter process under conditions 4 hours, 3 hours, 2 hours and one hour retention time, the removal efficiency of organic substance were 67.27 %, 53,89 5,45.70 % and 30.92 % respectively. And the removal efficiency of ammonia under conditions 3 hours, 2 hours and one hour retention time were 73.59 %, 67.98 %, and 48.74 % respectively. The longer retention time has resulted in higher removal efficiency. By combining biofiltration process with ultra fltration (UF) membrane technology, hence will be got technological alternative of drinking water process which able to degrade an organic matter and ammonia without chemicals instead of convensional process.  Kata Kunci : biofiltasi, membran, ultra filtrasi, air minum.

Abstract

Air limbah domestik memberikan kontribusi besar terhadap pencemaran air di perkotaan karena penerapan pengolahannya belum optimal. Penelitian kombinasi biofilter aerobik dengan media plastik sarang tawon (MPST) dan media kerikil (MK) dilakukan untuk mengolah air limbah domestik. Pemilihan proses mempertimbangkan baku mutu dan sasaran penerapannya untuk skala individual. Kombinasi pada HRT 24 jam menurunkan COD, NH4-N, TSS masing-masing 84,09%, 81,62%, 93,9%. Pada HRT 36 jam, menurunkan COD, NH4-N, TSS masing-masing 76,68%, 97,67%, 85,04%. Efisiensi dipengaruhi oleh variasi HRT dan perlakuan pada HRT 24 jam untuk meningkatkan kinerja reaktor, yaitu perubahan HRR dan tipe aerasi. Perubahan HRR dari 1 ke 0,25 (aerasi samping) meningkatkan kinerja reaktor dalam menurunkan COD dari 81,5% menjadi 88,05%, NH4-N dari 77,23% menjadi 81,7%, TSS dari 93,43% menjadi 96,35%. Perubahan tipe aerasi dari aerasi samping menjadi aerasi merata (HRR 0,25) meningkatkan kinerja reaktor dalam menurunkan NH4-N dari 81,7% menjadi 89,56%, sementara COD turun dari 88,05% menjadi 82,22% dan TSS turun dari 96,35% menjadi 90,66%. HRT 36 jam dipilih sebagai HRT optimum dengan aerasi merata dan HRR 0,25. Hal ini terkait efisiensi penurunan NH4-N yang sangat tinggi karena DO >2 mg/L dengan aerasi merata dan dalam HRT yang lebih lama, serta semua parameter berada di bawah baku mutu.Kata kunci:  air limbah domestik; biofilter aerobik; efisiensi penurunan; HRT
