The reuse of greywater has several advantages, including reduced freshwater extraction from rivers, aquifers, and groundwater; need for desalination; less environmental impact septic tanks water treatment plants; decreased energy consumption; chemical pollution. main objectives this review study are to assess the technical attributes, ecological impacts, cost-efficiency Moving Bed Biofilm React...

Abstract Aiming to mitigate wastewater pollution arising from the palm oil industry, this university-industry research-and-development project focused on integration of serial treatment processes, including use moving bed biofilm reactor (MBBR), pre-treatment with sand filters and activated carbon filters, membrane technology for aerobically-digested mill effluent (POME) treatment. To assess po...

Implementation of partial nitritation anammox (PNA) in the mainstream (municipal wastewater treatment) is still under investigation. Microbial community structure and reactor type can influence the performance of PNA reactor; yet, little is known about the role of the community composition of the inoculum and the reactor configuration under mainstream conditions. Therefore, this study investiga...

EXTENDED ABSTRACT The City College of New York (CCNY) in collaboration with New York City Environmental Protection (NYCEP) is currently engaged in operating a 1700 gallon pilot single stage partial nitritation/anaerobic ammonium oxidation (anammox) moving bed biofilm reactor (MBBR) at the 26th Ward waste water treatment plant (WWTP) in Brooklyn, NY. The MBBR is designed to remove nitrogen from ...

This experimental paper deals with the development of a hybrid biological reactor for treatment synthetic oilfield produced water under an increase in total dissolved solids (TDS) concentration. To comply strengthening regulations concerning discharge and peculiar compositions, moving bed biofilm (MBBR) consisting combination free activated sludge supports was compared to fixed (FBHBR) support....

This study was undertaken to evaluate the potential future use of three biological processes in order to designate the most desired solution for on-site treatment of wastewater from residential complexes, that is, conventional activated sludge process (CASP), moving-bed biofilm reactor (MBBR), and packed-bed biofilm reactor (PBBR). Hydraulic retention time (HRT) of 6, 3, and 2 h can be achieved...

Partial nitritation-anammox (PNA) permits energy effective nitrogen removal. Today PNA is used for treatment of concentrated and warm side streams at wastewater treatment plants, but not the more diluted and colder main stream. To implement PNA in the main stream, better knowledge about microbial communities at the typical environmental conditions is necessary. In order to investigate the respo...

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...
