Special Issue Information

Dear Colleagues,

The objective of this Special Issue is to gain insights into the main challenges and trends related to water treatment (e.g., drinking water, rainwater, desalination, wastewater, etc.). Articles focused on the development of new technologies and digitalization in water treatment are also of interest. We welcome the submission of original research articles, both methodological and experimental, and reviews covering all issues related to the above-mentioned topic.  

Possible topics include (but are not limited to) the following:

  • Drinking water treatment;
  • Desalination;
  • Rainwater purification systems;
  • Wastewater treatment;
  • Reclaimed water and wastewater reuse;
  • Modelling and simulation;
  • Digitalization;
  • Water–energy nexus;
  • Energy optimization,

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. Applied Sciences 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 2400 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.

A simple predictive analytical model for induction times in reverse osmosis (RO), both with and without an antiscalant (AS), has been developed based on the fundamental principles of mass and momentum balance. The simplicity of the model arises from the very low Reynolds number in the vicinity of the cluster surface, enabling the use and derivation of exact equations. The main assumption of the induction time without AS, t0A, is that the net growth of the cluster size results from the difference between adhesion and shear forces. With AS, the induction time, tA, is extended due to the competition between the AS and the scaling molecules on the cluster’s surface ligands. The model was validated by fitting it to six independent datasets from experiments conducted with spiral-wound and tubular RO membranes under various operational conditions, resulting in an average difference of 8.0% (t0A) and 8.7% (tA) between predicted and experimental induction times. It was found that t0A is governed by three dimensionless parameters: supersaturation ratio (Sa), shear (Ku), and scalant saturation (κ). tA increases with t0A and the AS concentration. Full article
