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 syngas chemical looping (SCL) process developed at the Ohio State University can efficiently convert coal derived syngas into hydrogen with in-situ CO2 capture. In this novel process, two moving bed units are used to convert syngas into hydrogen through the assistance of an oxygen carrier particle. A third unit, an entrained bed combustor, is used to convey the oxygen carrier particles to c...

Background: Phenolic compounds are found in wastewater of many industries such as pulp and paper, textile, petrochemical, oil refineries, production of phenolic resins, plastics, coal furnace, tannery, rubber reclamation plant, fertilizers, coke, paints, rubber, decolorizer, resins, rubber and phenol- formaldehyde resin industries. This study aimed to evaluate Moving Bed Biofil...

in a novel dual bed reactor fischer-tropsch synthesis was studied by using two diffrent cobalt catalysts. an alkali-promoted cobalt catalyst was used in the first bed of a fixed-bed reactor followed by a rutenuim promoted cobalt catalyst in the second bed. the activity, product selectivity and accelerated deactivation of the system were assessed and compared with a conventional single bed react...

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...

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...
