Rheological study of sludge of membranes bioreactors for water treatment: protocol, limitations and link with the filtration [PDF]
, 2011 The submerged membranes bio-reactors (sMBR) are more and more visible in the field of waste water treatment. The membrane fouling, that causes a drastic fall of the performances, can be limited by the application of a swarm of bubbles close to the ...

Aquaculture, Fish and Fisheries, Volume 6, Issue 3, June 2026.ABSTRACT Aquaculture intensification is increasingly constrained by high water demand, nutrient‐rich effluents and disease risk, increasing interest in biofloc technology (BFT) as a waste‐recycling, low‐exchange production model. However, BFT performance depends strongly on the carbon source used to adjust the carbon‐to‐nitrogen (C/N) ratio and ...

MICROBIAL FUEL CELLS USING DIFFERENT TYPES OF WASTEWATER FOR ELECTRICITY GENERATION AND SIMULTANEOUSLY REMOVED POLLUTANT [PDF]
Journal of Engineering Science and Technology, 2013 Microbial fuel cells (MFCs) are a device that converts chemical energy to electrical energy during substrate oxidation with the aid of microorganisms that act as biocatalysts. The energy contained in organic matter is converted to useful electrical power.
