in this study, feasibility of upgrading and retrofitting municipal wastewater treatment plantswas investigated at laboratory scale using moving bed biofilm reactor (mbbr) process. for this purpose,an aerobic pilot was operated for nearly one year in different conditions, in which a moving bed carrier with aspecific biofilm surface area of 500 m2/m3 and a filling rate of 60% was utilized. system...

Dairy industry wastewater is rich in organic content, presenting a high biodegradability, and therefore biological treatments are widely employed. This study aimed to evaluate biosolids production three systems: activated sludge (AS), movingbed biofilm reactor (MBBR), sequencingbatch (SBMBBR). Simulated dairy was used at different load rates (OLRs): 1.22, 2.87, 5.44 gCOD L−1d−1. Besides product...

background and purpose:moving bed biofilm reactor is an aerobic attached growth with better biofilm thickness control, lack of plugging and lower head loss. consequently, this system is greatly used by different wastewater treatment plants. high tds wastewater produced petrochemical, leather tanning, sea food processing, cannery, pickling and dairy industries. the aim of this study was to evalu...

For aquaculture wastewater with low ammonium nitrogen concentration, combining the carrier adsorption and biological removal processes can maximize their respective advantages. Functional ceramsite that has excellent performance biocompatibility was key to moving bed biofilm reactor (MBBR) adsorption—shortcut simultaneous nitrification denitrification (shortcut SND) process. Our group prepared ...

Consequently, this system is greatly used by different wastewater treatment plants. High TDS wastewater produced petrochemical, leather tanning, sea food processing, cannery, pickling and dairy industries. The aim of this study was to evalu...

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...

Moving bed biofilm reactor (MBBR) is a process in which attached growth is utilized for wastewater treatment. This process does not require sludge recycling or backwash. Activated sludge processes can be promoted to an MBBR by adding media to an aeration tank. Rapid sand filter is a physical method for the removal of total suspended solids (TSS) in advanced wastewater treatment. The purpose of ...
