ABSTRACT Leachate contains high levels of organic matter, TSS and ammonia. Moving Bed Biofilm Reactor (MBBR) is a biological treatment that can reduce the concentration contained in leachate. The purpose of this study was to determine the ability of MBBR to reduce the content of organic matter, TSS, and ammonia, by using variations in the detention time of aerobic-anoxic processes and sticky media. This research is a laboratory scale research. Leachate samples came from the Kotawaringin Timur TPA Inlet.  The reactor is operated in batches. During the aerobic process the moving media is assisted by an aerator pump and submersible pump, while in the anoxic process it is only from a submersible pump. The MBBR processing used has a capacity of 5L with a media capacity of 2L. The variations of the media used were K1 and K3 caldness, while the aerobic detention time was 14.5 hours - anoxic 10 hours and aerobic 10 hours anoxic 7 hours. The results obtained show that MBBR can be used to treat leachate. The best decrease in COD, TSS, and ammonia concentrations occurred in K1 media with 14.5-anoxic 10-hour aerobic detention time with a reduction of 74.8%, 93.14%, and 83.72%.

Semakin banyaknya usaha rumah makan, maka air limbah yang dihasilkan akan bertambah dan akan menjadi suatu permasalahan. Pada proses pengolahan limbah khususnya yang mengandung senyawa organik, salah satu teknologi yang digunakan adalah dengan menggunakan proses Moving Bed Bioflm Reactor (MBBR). Pada prinsipnya, MBBR merupakan proses lumpur aktif yang ditingkatkan dengan menambahkan media (carrier) ke dalam reaktor aerasi. Penelitian ini bertujuan menganalisis penurunan zat organik COD dan TSS dengan menggunakan proses MBBR pada limbah domestik rumah makan. Pada penelitian ini media yang digunakan adalah media kaldness 1 (K1) dengan variasi volume media yaitu tanpa media, 15%, 30%, 45%, dan 60%, serta variasi debit aliran air limbah yang akan masuk ke dalam reaktor MBBR sebesar 15 ml/menit, 30 ml/menit, 45 ml/menit, 60 ml/menit, dan 75 ml/menit. Hasil penelitian ini menunjukan bahwa kemampuan penyisihan beban pencemar COD dari limbah air domestik rumah makan oleh reaktor MBBR dengan volume media 60% dan debit 15 ml/menit sangat efektif. Reaktor ini mampu menurunkan nilai COD hingga 97,73% dan untuk TSS hanya sebesar 63,04% karena pada penelitian ini tidak menggunakan bak pengendap akhir sehingga nilai penyisihan TSS tidak terlalu besar.  Kata kunci:  COD, kaldness 1, moving bed bioflm reactor, TSS The more business restaurant, wastewater will be produced.

Development of a MBBR-MBR has been investigated combining a moving bed biofilm reactor with a submerged membrane biomass separation reactor. Treatment efficiencies were found to be high with the production of a consistent high-quality effluent, irrespective of media fill ratio of MBBR or membrane reactor operating modes. There had some obvious fouling in MBR, MBBR and IFAS 3000, while no fouling were detected in IFAS 1500. The great difference indicated the media filling fraction have an important role and effect on membrane fouling. Traditional MBR and IFAS 3000 have more non-flocculating microorganisms in most time due to the mixed liquor suspended solids (MLSS) concentration. There had almost the same MLSS on media surface, independent of the volume of media and the MLSS concentration in each tank. The MBBR had more biomass enriched on membrane surface due to the dead end system.

This work aimed to achieve partial nitrification (PN) in a Sequencing Moving Bed Biofilm Reactor SMBBR with zeolite as a biomass carrier by using sulfide pulses in the presence of organic matter as an inhibitor. Two conditions were evaluated: sulfide (HS−) = 5 mg S/L and vvm (air volume per liquid volume per minute, L of air L−1 of liquid min−1) = 0.1 (condition 1); and a HS− = 10 mg S/L and a vvm = 0.5 (condition 2). The simultaneous effect of organic matter and sulfide was evaluated at a Chemical Oxygen Demand (COD) = 350 mg/L and HS− = 5 mg S/L, with a vvm = 0.5. As a result, using the sulfide pulse improved the nitrite accumulation in both systems. However, Total Ammonia Nitrogen (TAN) oxidation in both processes decreased by up to 60%. The simultaneous presence of COD and sulfide significantly reduced the TAN and nitrite oxidation, with a COD removal yield of 80% and sulfide oxidation close to 20%. Thus, the use of a sulfide pulse enabled PN in a SMBBR with zeolite. Organic matter, together with the sulfide pulse, almost completely inhibited the nitrification process despite using zeolite.

Abstract Greywater is an important non-conventional water resource which can be treated and recycled in buildings. A decentralized greywater recycling system for 223 inhabitants started operating in 2006 in Berlin, Germany. High load greywater undergoes advanced treatment in a multistage moving bed biofilm reactor (MBBR) followed by sand filtration and UV disinfection. The treated water is used safely as service water for toilet flushing. Monitoring of the organic matter degradation was pursued to describe the degradation processes in each stage and optimize the system. Results showed that organic matter reduction was achieved for the most part in the first three reactors, whereas the highest reduction rate was observed in the third reactor in terms of COD (chemical oxygen demand), dissolved organic carbon and BOD7 (biological oxygen demand). The results also showed that the average loading rate entering the system was 3.7 kg COD/d, while the removal rate was 3.4 kg COD/d in a total bioreactor volume of 11.7 m³. In terms of BOD, the loading rate was 2.8 kg BOD/d and it was almost totally removed. This system requires little space (0.15 m²/person) and maintenance work of less than one hour per month and it shows operational stability under peak loads.

Wastewaters from three integrated newsprint mills have been treated in a pilot plant Moving Bed Biofilm Reactor (MBBR). In the MBBR the biomass adheres to small plastic elements which move freely along with the water in the reactor. A reduction of 65-75% for COD and 85-95% for BOD was obtained at HRT of 4-5 hours. By prolonging the HRT the removal efficiencies of COD and BOD increased to about 80% and 96%, respectively. With a subsequent chemical precipitation a removal efficiency of COD up to 95% was achieved. The amount of chemicals needed for precipitation of the biologically treated wastewater was only a quarter to a third of that needed for chemical treatment of the untreated wastewater. The results showed the MBBR process to be competitive with conventional biological treatment systems and that treatment objectives can be met at short HRTs.
