Background and purpose: The performance of full-scale moving bed biofilm reactor (MBBR) was evaluated as an alternative for upgrading of Kish Island Mirmohana wastewater treatment plant. In this study activated sludge process upgrade to MBBR process and different operating parameters were compared. Materials and Methods: Effect of upgrading on different parameters such as organic loading rate (...

The purpose of this study is to investigate the accuracy of predictions of aniline removal efficiency in a moving bed biofilm reactor (MBBR) by various methods, namely by RBF, ANFIS, and fuzzy regression analysis. The reactor was operated in an aerobic batch and was filled by light expanded clay aggregate (LECA) as a carrier for the treatment of Aniline synthetic wastewater. Exploratory data an...

One of the requirements for environmental engineering, which is currently being considered, is the removal of ethylene glycol (EG) as a hazardous environmental pollutant from industrial wastewater. Therefore, in a recent study, a moving bed biofilm reactor (MBBR) was applied at pilot scale to treat industrial effluents containing different concentrations of EG (600, 800, 1200, and 1800 mg L-1 )...

Many industries generate phenolic wastewater of acidic nature. Neutralization with sodium hydroxide generates the phenolic wastewater with high TDS. Both phenol and ionic concentration of TDS are inhibitor to biological treatment processes. A study was carried out for biological treatment of phenolic wastewater with high total dissolved solid (TDS) concentration in moving bed biofilm reactor (M...

Moving bed biofilm reactors (MBBRs) are increasingly used for nitrogen removal with nitritation-anaerobic ammonium oxidation (anammox) processes in wastewater treatment. Carriers provide protected surfaces where ammonia oxidizing bacteria (AOB) and anammox bacteria form complex biofilms. However, the knowledge about the organization of microbial communities in MBBR biofilms is sparse. We used n...

Instalasi Pengolahan Air Limbah Industri Pemerahan Sapi dengan sistem lumpur aktif seringkali mengalami masalah, salah satunya adalah masalah sludge bulking. Permasalahan bulking menyebabkan pengendapan sangat buruk dan melimpah menuju outlet bak sedimentasi unit selanjutnya. Hal ini mengakibatkan kualitas pengolahan tidak berjalan optimal hasil masih sering keruh berbau. Salah satu solusi untu...

The digestibility of proteins in red kidney bean (Phaseolus vulgaris L.) was examined by in vitro pepsin assay. A 20-kDa polypeptide that remained highly stable after heat processing was identified as a basic subunit of legumin. The results of a monobromobimane (mBBr) labeling test implied that this protein contained rigid intramolecular disulfide bonds, which might contribute to pepsin resista...

Two bench-scale parallel moving bed biofilm reactors (MBBR) were operated to assess pH-associated anammox activity changes during long term treatment of anaerobically digested sludge centrate pre-treated in a suspended growth partial nitrification reactor. The pH was maintained at 6.5 in reactor R1, while it was allowed to vary naturally between 7.5 and 8.1 in reactor R2. At high nitrogen loads...

The study aims to compare three sewage biological treatment methods- activated sludge, moving bed biofilm reactor (MBBR), and fixed reactor. sludge method is the most used in ship treatment. However, carrier methods, such as MBBR reactors, have improved their effectiveness with industrial wastewater, being considered industrial. An experiment was carried out untreated samples, chemical oxygen d...
