A microbial reverse-electrodialysis electrolysis cell (MREC) was used to produce hydrogen gas from fermentation wastewater without the need for additional electrical energy. Increasing the number of cell pairs in the reverse electrodialysis stack from 5 to 10 doubled the maximum current produced from 60 A/m(3) to 120 A/m(3) using acetate. However, more rapid COD removal required a decrease in t...

In the leather and fur industry, possibility of using electrochemically activated solutions has not been properly evaluated, although such processing raw materials can contribute to autonomy production in context import substitution reduce environmental burden enterprises on environment. The work is aimed at optimizing technological processes for anolyte. Anolyte an solution sodium chloride, ob...

BACKGROUND Washbasin U-bends are reservoirs of microbial contamination in healthcare environments. U-Bends are constantly full of water and harbour microbial biofilm. AIM To develop an effective automated cleaning and disinfection system for U-bends using two solutions generated by electrochemical activation of brine including the disinfectant anolyte (predominantly hypochlorous acid) and cat...

Bunsen reaction was performed electrochemically using cation exchange membranes prepared by a radiation-induced grafting method for application to the iodine-sulfur thermochemical water-splitting cycle. The reaction experiments using sulfuric acid dissolving sulfur dioxide as the anolyte and hydriodic acid dissolving iodine as the catholyte verified the progress of the aimed reaction. Compared ...

A miniature microbial fuel cell (mini-MFC) is described that demonstrates high output power per device cross-section (2.0 cm2) and volume (1.2 cm3). Shewanella oneidensis DSP10 in growth medium with lactate and buffered ferricyanide solutions were used as the anolyte and catholyte, respectively. Maximum power densities of 24 and 10 mW/m2 were measured using the true surface areas of reticulated...

Double conjugate addition leads to an increased stability and voltage for this amine functionalised quinoidal anolyte designed basic aqueous redox flow batteries, suggesting that such a reaction does not always lead degradation.

For the development of long lasting portable microbial fuel cells (MFCs) new strategies are necessary to overcome critical issues such as hydraulic pump system and the biochemical substrate retrieval overtime to sustain bacteria metabolism. The present work proposes the use of a synthetic solid anolyte (SSA), constituted by agar, carbonaceous and nitrogen sources dissolved into diluted seawater...
