Special Issue Information

Dear Colleagues,

The combination of sensors and data processing offers new insights into many disciplines, and also in water treatment. The Internet of Things is abundantly applied, which drastically reduces the connection cost. Therefore, the use of more and other sensor types is becoming very interesting. For example, the use of many sensors integrated into the main material is possible, using, for example, crack detection sensors, or conductivity measurement for a relatively low cost. Which sensors are used now, and which sensor types are emerging?

Data from all sensors can be processed by artificial intelligence, leading to a much more defined insight into water networks and water quality. Leak detection, water quality assurance, and threat detection are improved massively. Integration with other systems (e.g., the energy grid) increases this information awareness even more.  Which information is required for normal operation, and what is interesting for new business cases? What is the future, which information is not accessible yet, and which sensors do we possibly need for that? Finally, what can the public do with the available information? For example, direct feedback regarding water scarcity and water use will likely prompt users to adapt their water use.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Water is essential for society. Due to excellent distribution systems for clean drinking water and wastewater, safe and reliable water transport is guaranteed. However, due to ageing network conditions, there is a need for extensive network monitoring and replacement strategies. There is a high demand for good insight into water mains and water distribution systems. A promising way to monitor our water transport involves various types of novel sensors, including strategies for the smart placement of these sensors, maximizing performance while minimizing costs. Furthermore, processing the increasingly large amount of sensor data can be done using Artificial Intelligence and sensor fusion techniques, yielding vastly increased information about the distribution mains.

In this study, the simultaneous enzymatic decolorization of reactive blue 221 (RB221) and the performance of different electrode carbon nanotube (CNT)-modified/unmodified carbon graphite cathodes were investigated in a dual-chamber Microbial Fuel Cell (MFC) at a permanent temperature of 25 °C.

In this study, the simultaneous enzymatic decolorization of reactive blue 221 (RB221) and the performance of different electrode carbon nanotube (CNT)-modified/unmodified carbon graphite cathodes were investigated in a dual-chamber Microbial Fuel Cell (MFC) at a permanent temperature of 25 °C. The maximum power density and maximum voltage increased by approximately 13.6% and 50%, respectively, when using the CNT-modified carbon graphite electrode as the cathode. A suspended laccase enzyme was utilized in the cathode compartment for dye decolorization. In the absence of the dye, laccase caused an increase in power density to about 28%. In addition, this research revealed that an initial dye concentration of 80 mg/L simultaneously resulted in an enzymatic decolorization efficiency of 73.4% in the cathode chamber and 82.3% chemical oxygen demand (COD) removal of sucrose in the anode chamber. Finally, this study substantiates the fact that an MFC equipped with a CNT-modified carbon graphite electrode can be used for bioelectricity generation and effective dye removal. Full article
