Special Issue Information

Dear Colleagues,

Water resource management in general and wastewater treatment, valorization, and reuse in particular are currently considered as important worldwide challenges. In this context, the 2030 United Nations Agenda for Sustainable Development Goals (UN-SDGs) aims to improve water quality by reducing pollution, eliminating dumping, and minimizing the release of hazardous chemicals and materials, halving the proportion of untreated wastewater and substantially increasing recycling and safe reuse globally. Currently, the paradigm of wastewater management is shifting from “treatment and disposal” to “reuse, recycle, and resource recovery”. The main benefits of this new concept concern not only human and environmental health, food, and energy security but also climate change mitigation. Hence, in the context of a circular economy, whereby economic development must be balanced with natural resource preservation and environmental sustainability, wastewater can be considered an abundant source of precious and sustainable resources.

Themes of this Special Issue include, but are not limited to, the following:

  • Wastewater treatment technologies;
  • Innovative technologies for the removal of emerging pollutants;
  • Decentralized wastewater treatment systems;
  • Sewage biosolid management (methanization, composting, land application, etc.);
  • Resource (struvite/energy) recovery from wastewater;
  • Reuse of recovered resources from wastewater;
  • Reuse of reclaimed wastewater (agriculture, groundwater recharge, industry, etc.);
  • Wastewater reuse policies;
  • Wastewater reuse and monitoring.

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.

Reverse osmosis technique was applied in removing hexavalent chromium ions from artificial wastewater. Different operating conditions were studied to monitor the separation process using commercial Reverse Osmosis BW30XFR membrane. Different concentrations of hexavalent chromium; 5, 30, and 100 ppm were tested. Samples were subjected to incrementally increasing operating pressure; 10, 30, and 45 bar and flow rates; 2.2, 3.4, and 4.5 L/min under various temperatures; 25, 35, 45, and 55 °C. Collected permeate and concentrations were measured after each experiment using a UV spectrophotometer. Results obtained presented a higher rejection percentage at lower feed concentrations with a value up to 99.8% for 5 ppm in comparison to 94.3% for 30 ppm and 77.2% for 100 ppm concentration due to concentration polarization; however, it showed no effect of increasing operating flow rates. Moreover, the increase in feed temperature from 25 to 55 °C had positively increased permeate flux to more than 300 times. The permeate flux at 25 °C is recorded for all tested samples in the range of 30 to 158 kg/h·m2, this range has risen at 55 °C under the same conditions to the range of 70 to 226 kg/h·m2, indicating alteration within the membrane pore size due to temperature increase and high applied pressure concluding high sensitivity of polymeric membranes towards changing permeate flow rate with increasing temperatures.

Terrorism is a crucial danger to the world, especially the Middle East. As Jordan is amidst countries with armed conflicts, its natural resources (in particularly, water resources) are vulnerable to terrorist attacks. In this paper, possible biological and chemical weapons that can be used as intimidation, along with their threats, vulnerabilities, and inactivation methods, concerning water treatment processes in the municipality of Irbid, are studied. Irbid is the second largest city in terms of population in Jordan, after the capital city of Amman, and it is the nearest governorate to Syria borders that is considered a war zone. After conducting risk assessment that takes into consideration criticality, threats, and vulnerability, it appears that only one of the eight units, which is the Makhraba pumping station, along with the Bushra water tank, were identified as medium risk. The other units have treatment processes and proper precautions that are able to inactivate or prevent any possible contamination. A response plan should be set by developing a telemetry system with specific sensors that can detect any sudden and unacceptable threats to the water quality and that has the ability to shut down the concerned units automatically.
