A method for the calculation of the depth of the current line penetration between the edges of the electrodes and the side walls of the cell in a cell with plane parallel electrode arrangement is proposed. The method is verified by the calculation of the polarization curves for the cells in which the electrode edges do not touch the side walls of the cell. The agreement between the calculated and the measured values was fair.

The present study investigated the parameters and the mechanism of action of electrochemical cell lysis to reduce the return sludge from secondary settlers based on the theory of cell lysis-cryptic growth. The factors influencing the functioning of two electrodes (Ti/SnO2-Sb and Ti/RuO2-IrO2) were investigated to determine the optimal cell lysis parameters for each electrode, and the effects of the two electrodes on cell lysis were compared under these conditions. Finally, the Ti/SnO2-Sb electrode was selected for the subsequent experiments. The electrolysis reaction was performed using the following parameters: the initial sludge concentration was 7000 mg/L, the working voltage was 18 V, the plate spacing was 1 cm, the initial pH was 6.8 to 7.0, and the electrolysis duration was 90 min. The degree of disintegration of the sludge and the cell lysis rate reached 25.35% and 20.15%, respectively. In summary, electrochemical cell lysis has a good prospect for sludge reduction.

Photoelectrochemical production of hydrogen peroxide was studied by using a cell functioning with a WO3 photoanode and an air breathing cathode made of carbon cloth with a hydrophobic layer of carbon black. The photoanode functioned in the absence of any sacrificial agent by water splitting, but the produced photocurrent was doubled in the presence of glycerol or ethanol. Hydrogen peroxide production was monitored in all cases, mainly in the presence of glycerol. The presence or absence of the organic fuel affected only the obtained photocurrent. The Faradaic efficiency for hydrogen peroxide production was the same in all cases, mounting up to 74%. The duplication of the photocurrent in the presence of biomass derivatives such as glycerol or ethanol and the fact that WO3 absorbed light in a substantial range of the visible spectrum promotes the presently studied system as a sustainable source of hydrogen peroxide production.

It was shown that the current density-cell voltage curves recorded in a cell with parallel plate electrodes for different distances between the edges of the electrodes and side walls of the cell can be used to determine the current distribution in cells of the Haring-Blum type.

In the purpose of in situ control of hydrodynamic influence on electrochemical processes, a cell jet device has been conceived and characterized. This cell was sensitive to parameters that are the jet tube diameter, and its height versus the working electrode. So, the three hydrodynamic flow modes have been established from the non dimensional Reynolds number. From the use of this cell for the study of co deposition from the Ni/SiC system with a WATT bath, it was shown that the turbulent flow to favor more embedment of SiC particles in the nickel matrix. It also noted an influence of the flow mode and SiC particles on the working current.
