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...

In this research, the continuously operated laboratory scale Kaldnes (k1) moving bed biofilm reactors (MBBRs) under partial nitrification-denitrification process were used for treatment of synthetic wastewater containing ammonium and glucose. The Anoxic and Aerobic reactors were filled to 40 and 50 %( v/v) to attach and retain biomass with k1 biofilm carriers, respectively. The favorite interna...

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...

Wine distillery wastewater, commonly called vinasses, was treated by an anaerobic moving bed biofilm reactor (AMBBR) with 32.9 litre available volume. The reactor was filled with 66% cylindrical polyethylene supports with density 0.84 g cm(-3) as a biofilm carrier. The reactor was sequentially mixed by a submerged centrifugal pump fixed to the bottom, and each mixing time just lasted 1.25 minut...

anaerobic treatment methods are more suitable for the treatment of concentrated wastewater streams, offer lower operating costs, the production of usable biogas product. the aim of this study was to investigate the performance of an anaerobic fluidized bed reactor (afbr)-aerobic moving bed bio reactor (mbbr) in series arrangement to treat currant wastewater.the bed materials of afbr were cylind...

A novel wastewater treatment system has been developed, utilizing an oxygen-rich algal liquid to supply oxygen to an aerobic biofilm reactor. Aerobic treatment of wastewater takes place in a Moving Bed Biofilm Reactor, where the aerobic biomass which breaks down organic and nitrogenous pollutants grows as a biofilm on floating carriers. Algae grown in an open raceway pond produce oxygen through...
