Special Issue Information

Dear Colleagues,

The development of innovative wastewater treatment processes is considered a fundamental task for various researchers and companies, since the re-utilization of wastewater in the same process that has generated it is one of the pillars of a circular economy. The process of intensification may allow maximizing the process performances by means of innovative equipment or particular operative conditions. For instance, various biological/chemical and physical treatments can be intensified by optimizing the fluid dynamics conditions established in the used reactor. A number of innovative treatment processes have been developed in the last decades, taking advantage of different energy sources and phenomena (cavitation, microwaves, ultrasounds, etc.) or by means of nano-photo/catalysts, such as iron-based, zinc-based, and titanium-based nanoparticles.

In this Special Issue, interested researchers are invited to submit original research papers, as well as review articles, on any topic related to the intensification of well-known biological/chemical or physical wastewater treatment or related to the development of innovative treatment processes, focusing on organic pollutant degradation/removal. The studies should report the experimental data modelling and/or possible equipment modelling for industrial scale-up of the proposed technology.

Earth Pressure Balance (EPB) Tunnel Boring Machines (TBM) are currently the most widely used machines to perform tunnel excavation, particularly in urban areas. This technology involves the injection of chemicals as conditioning mixtures, which commonly raises concerns limiting the reuse of soils after excavation. This study deals with the prospect of a simplified, rapid and replicable methodology for the evaluation of the biodegradability of these conditioning mixtures. For this purpose, the biodegradation of three commercial conditioning mixtures was investigated in closed bottle tests by investigating the effect of different mixtures dosages and two different inocula (soil humus and Bacillus Clausii). While using soil humus as inoculum, a comparative study of biodegradation of the three investigated mixtures was successfully carried out; in the case of Bacillus Clausii, it was not possible to make a comparison between the different formulations in a short time. The adoption of soil humus satisfied only the criteria of rapid test, while the Bacillus Clausii, as specific inoculum, can meet the criteria of replicable results. For this reason, in the second part of this experimental study, a rapid and replicable procedure was proposed and validated. A kinetic study of organic carbon removal was also carried out.
