Removal and fate of micropollutants in a sponge-based moving bed bioreactor.

Moving Bed Biofilm Reactor Performance in Phenol Removal from Wastewater

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...

Roles of polyurethane foam in aerobic moving and fixed bed bioreactors.

The aim of this study was to investigate the performance of sponge as an active mobile carrier for attached-growth biomass in three typical types of aerobic bioreactors to treat a high strength synthetic wastewater. The results show that sponge thickness deteriorated the organic and nutrient removal and 1cm is the optimum thickness for fixed-bed sponge biofilter (SBF). The sponge volume had sig...

Effect of sponge volume fraction on the performance of a novel fluidized bed bioreactor.

A novel fluidized bed bioreactor (FBBR) was designed by integration of anaerobic granular activated carbon and aerobic sponge reactors. This FBBR was evaluated at different sponge volume fractions for treating a synthetic wastewater. Polyester urethane sponge with cube size of 1 × 1 × 1 cm and density of 28-30 kg/m(3) with 90 cells per 25 mm was used as biomass carrier. The results indicate tha...

Biological Phosphorus and Nitrogen Removal from Wastewater Using Moving Bed Biofilm Process

In this research, an experimental study to evaluate nutrient removal from synthetic wastewater by a lab-scale moving bed biofilm process was investigated. Also, kinetic analysis of the process with regard to phosphorus and nitrogen removal was studied with different mathematical models. For nutrient removal, the moving bed biofilm process was applied in series with anaerobic, anoxic and aerobic...
