Special Issue Information

Dear Colleagues,

Catalytic processes play an extremely important role in wastewater treatment, especially for the pre-oxidation step and advanced purification step. One of the keys to the innovation of wastewater treatment technology lies in the breakthrough of the bottleneck of catalytic oxidation technology and the solution of engineering application problems.

Therefore, this Special Issue of Water will focus on the latest innovative catalytic processes in wastewater treatment: from mechanisms to application. Papers will present novel insights on the mechanisms and application of various catalytic water treatment technologies, such as Fenton/Fenton-like technology, catalytic ozonation technology, photocatalytic technology, electrocatalytic technology, peroxymonosulfate/persulfate activation technology, and so on.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

1) New discovery in catalytic water treatment processes;

2) New mechanisms of catalytic processes in wastewater treatment technology;

3) New materials for catalytic wastewater treatment with high efficiency and low consumption;

4) Application case analyses on catalytic wastewater treatment technology.

I look forward to receiving your contributions.

The adsorption process combined with electrocoagulation is a highly effective technique for dye removal. Calcinized and non-calcinized composites based on bentonite and sodium zeolite were prepared for adsorptive removal of Foron EBL blue, Terasil brown 2RFL, Torque blue PG, and Orange P3R dyes. Factors affecting the adsorption process, such as contact time, initial dye concentration, and temperature, were also explored in this study. Equilibrium data of natural clay composites was explained by Freundlich, Langmuir, Dubinin Radushkevich isotherm, Harkin Jura, and Temkin isothermal models. Harkin Jura isotherm model best fitted on the adsorption mechanism compared to Langmuir and Temkin isotherm model. Morphology of clay-based adsorbents and functional group arrangement were investigated by scanning electron microscopy (SEM) and Fourier-transform infrared spectroscopy (FTIR). The calcinized nano-composite material exhibited better adsorption capacity than non-calcinized nano-composite and could be employed as a low-cost alternative for dye removal. Full article
