Background: High concentration of salt makes biological treatment impossible due to bacterial plasmolysis. The present research studies the process of electrochemical oxidation efficiency and optimal levels as important factors affecting pH, salt concentration, reaction time and applied voltage. Methods: The sample included graphite electrodes with specifications of 2.5 cm diameter and 15 cm he...

Microbial electrochemical technologies (METs) rely on the control of interactions between microorganisms and electronic devices, enabling to transform chemical energy into electricity. We report a new approach to construct ready-to-use artificial bioelectrodes by immobilizing Geobacter sulfurreducens cells in composite materials associating silica gel and carbon felt fibres. Viability test conf...

Electrocoagulation is a group of various procedures used for removing contaminants from water by electrochemically dissolving aluminum or iron. The contaminants of the solution may be incorporated in the in situ forming metal hydroxide flocs, which can be filtered as a precipitate or skimmed as a float. The main features of the procedure are highlighted on the example of cleaning of an oily was...

Fe(3)O(4) nanoprisms, synthesized by a solvothermal process, exhibited crystal plane dependent electrochemical activities, which opens an approach to nanoscale materials with controlled electrochemical properties.

This paper presents the Optimization of Non-Traditional Machining (NTM) process for the Electrochemical Machining Process by Particle Swarm Optimization Technique. The main aim of the work is to find the optimum values of machining parameters. The NonTraditional or Unconventional Machining Process has proved to be better than conventional machining process to a large extent. Keywords—Convention...

This study aimed to characterize the effects of ethanol on the monopolar electrochemical process to remove Bacillus subtilis spores from drinking water. In particular, spores' destruction was tested by applying 20-100 mA current for 15-60 min to B. subtilis spores (10(2)-10(4) CFU/mL density), with stainless steel electrodes. The experimental results showed electrochemical removal of spores in ...
