This study evaluates the efficiency of domestic wastewater treatment via Sponge-Based Moving Bed Biofilm Reactor (S-MBBR). The laboratory-based treatment plan uses polyurethane sponge with a specific surface area was 260 m<sup>2</sup>/m<sup>3</sup> as a carrier. The treatment plan operated under four different organic load rate: OLR1 = 0.4 kg BOD/m<sup>3</sup>.day; OLR2 = 0.6 kg BOD/m<sup>3</sup>.day; OLR3 = 0.8 kg BOD/m<sup>3</sup>.day; and OLR4 = 1.0 kg BOD/m<sup>3</sup>.day. During 80 d of the experiment, the highest treatment efficiency was at the organic load rate of 0.4 kg BOD/m<sup>3</sup>.day, with COD, SS, TN and TP were found to be 85.0 ± 12.9%, 85.7 ± 5.3%, 68.9 ± 1.7%, and 40.3 ± 0.2%, respectively. In which, the influent SS concentration were from 117.3 to 126.0 mg/L, the effluent concentration were in ranged 18.0 to 34.22 mg/L, respectively. The values of influent and effluent COD were 298.8 ± 12.88 and 44.8 ± 3.78 mg/L in turn. The OLR1 influent TN, TP concentrations were respectively 47.9 ± 2.11 and 3.6 ± 0.15 mg/L; the effluent TN, TP concentration were 14.9 ± 0.18 and 2.2 ± 0.06 mg/L, respectively. The study suggests that the effluent is within the allowable limits of National technical regulation on domestic wastewater (Column B1), indicating the applicability of S-MBBR for the domestic wastewater treatment plant.

One of the alternative technologies that could be used for domestic waste water treatment is the Moving Bed Biofilm Reactor (MBBR). MBBR in principle is activated sludge that is increased by adding media in to the reactor, so there are two treatments process happened inside, suspended growth and attached growth. This research is using bioball as a media which has surface area of ±210 m2/m3 by 20% volume of reactor volume. Wastewater treatment by MBBR uses variations of Hydraulic Retention time (HRT) 12, 8, 6, and 4 hours, then the parameters measured were BOD, COD, TSS, temperature, and pH. Result of the study shows that within HRT for 12 hours in aeration tank, removal efficiency of COD is 81,37%, BOD is 82,4%, and TSS is 90,05%. HRT for 8 hours, COD removal efficiency is 88,72%, BOD is 89,7%, and TSS is 92,06%. HRT for 6 hours, COD removal efficiency is 85,48%, BOD is 80,15%, and TSS is 94,85%. HRT for 4 hours, COD removal efficiency is 81,07%, BOD is 87,88%, and TSS is 94,86%. With a retention time of 4 hours, the effluent results domestic wastewater treatment using MBBR has met quality standards in accordance with KEPMEN LH no. 112 of 2003 on Domestic Wastewater Quality Standard and Jakarta Governor Regulation no. 122 of 2005 on Domestic Wastewater Management in Special Province of Jakarta. Keywords: Domestic wastewater, MBBR, bioball.

Abstract Biological reactors with immobilized biomass on free carriers have provided new perspectives for wastewater treatment, once they reduce the system size and increase the treatment capacity. In this study, the performance of three Moving Bed Biofilm Reactors (MBBR) using different carriers (with and without protected surface area) were evaluated for domestic wastewater treatment in continuous flow. Each MBBRs (i.e., R1, R2, and R3) was filled at a ratio of 50% with high-density polyethylene carriers with different characteristics: both R1-K1 and R2-Corrugated tube with protected surface and R3-HDPE flakes without protected surface. Chemical oxygen demand (COD) removal of 80 ± 5.0, 80 ± 3.5, and 78 ± 2.4% was achieved by R1, R2, and R3, respectively. The oxygen uptake by biofilm attached on the carriers was 0.0079 ± 0.0013, 0.0033 ± 0.0015, and 0.0031 ± 0.0026 μg DO·mm−2 for the K1, corrugated tube, and HDPE flakes, respectively. No significant differences were observed between the performance of the three MBBRs in terms of physico-chemical parameters (alkalinity, pH, and dissolved inorganic carbon) and COD removal. Results showed that the carrier type and its characteristics (total area and with/without protected area) did not affect the organic matter removal. Thus, the carrier without a protected surface in MBBR could be a promising low-cost option for domestic wastewater treatment.

Abstract The increase in the number of hotels in Pontianak City has a impact, namely the increase in the generation of wastewater. The hotel wastewater treatment process is widely used by hotels in Pontianak, especially at the Aston hotel, which already has a sewage treatment plant with suspended biological treatment. The processed water often does not meet the quality standards of wastewater which may be disposed of in accordance with PERMEN/LH/68/2016 concerning domestic wastewater quality standards. In this study, the parameters measured were BOD, TSS and pH. The purpose of this study was to determine the efficiency of Aston hotel wastewater treatment using an attached reactorMBBR (moving bed biofilm reactor) with Kaldnes K3 media in reducing BOD and TSS parameters. Growing microorganisms and biofilms on adhesive media for 14 days. Giving Kaldnes K3 adhesive media as much as 30%. Based on the research results of Aston hotel wastewater treatment with attached reactor MBBR able to reduce BOD and TSS parameters. Best lowering efficiency in attached reactor MBBR with the best time of 7 days was able to reduce the BOD parameter from 109.81 mg/L became 7.28 mg/L with an efficiency of 93.37%, and the TSS parameter decreased from the initial concentration of 78 mg/L to 8 mg/L and the efficiency was 89.74%.  Keywords : BOD, Kaldnes, Hotel Waste Waste, MBBR, TSS Abstrak Peningkatan jumlah hotel di Kota Pontianak memberi dampak, yaitu meningkatnya timbulan limbah cair.

The aim of this study was to evaluate the performance of a full-scale upgrading of an existing RBC wastewater treatment plant with a MBBR (Moving Bed Biofilm Reactor) system, installed in a tank previously used for sludge aerobic digestion. The full-scale plant is located in a mountain resort in the North-East of Italy. Due to the fact that the people varied during the year's seasons (2000 resident people and 2000 tourists) the RBC system was insufficient to meet the effluent standards. The MBBR applied system consists of the FLOCOR-RMP®plastic media with a specific surface area of about 160 m2/m3 (internal surface only). Nitrogen and carbon removal from wastewater was investigated over a 1-year period, with two different plant lay-outs: one-stage (only MBBR) and two stage system (MBBR and rotating biological contactors in series). The systems have been operated at low temperature (5–15°C). 50% of the MBBR volume (V=79 m3) was filled. The organic and ammonium loads were in the average 7.9 gCOD m−2 d−1 and 0.9 g NH4−N m−2 d−1. Typical carbon and nitrogen removals in MBBR at temperature lower than 8°C were respectively 73% and 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.

In 1988 the State Pollution Control Authority in Norway made recommendations regarding process designs for small wastewater treatment plants. Amongst these were recommendations for biological/chemical plants where biofilm reactors were used in combination with pretreatment in large septic tanks and chemical post treatment. At the same time the socalled “moving bed biofilm reactor” (MBBR) was developed by a Norwegian company. In this paper, experiences from a small wastewater treatment plant, based on the MBBR and on the recommendations mentioned, will be presented.
