Effects of packing rates of cubic-shaped polyurethane foam carriers on the microbial community and the removal of organics and nitrogen in moving bed biofilm reactors

, 2012
The effects of packing rates (20%, 30%, and 40%) of polyurethane foam (PUF) to the removal of organics and nitrogen were investigated by continuously feeding artificial sewage in three aerobic moving bed biofilm reactors.

DEGRADATION OF AROMATIC COMPOUNDS USING MOVING BED BIOFILM REACTORS [PDF]

, 2007
For biological treatment of water, there are many different biofilm systems in use. Examples of them are trickling filters, rotating biological contactors, fixed media submerged biofilters, granular media biofilters and fluidized bed reactors.

Phosphorus and Nitrogen Removal in Moving-Bed Sequencing Batch Biofilm Reactors

Water Science and Technology, 1999
A pilot moving-bed sequencing batch biofilm reactor (MBSBBR) fed with primary settled wastewater, was used in order to study organic carbon, phosphorus and nitrogen removal with and without external carbon sources. Patented KMT® polyethylene biofilm carriers were used.

Butanol production by clostridium acetobutylicum in a series of packed biofilm bed reactors [PDF]

, 2016
The reactor design plays a key role in the fermentative production of biobutanol. The high cell concentration that may be reached in confined – biofilm, membrane, recycling - cell reactors offers high conversion rates.

Upgrade and reconstruction of biological processes in municipal wastewater treatment plants

Desalination and Water Treatment
Traditional activated-sludge treatment technologies, such as anaerobic/anoxic/aerobic processes, oxidation ditch processes, and sequential batch reactors, play a crucial role in the removal of nitrogen and phosphorus from municipal wastewater.
