Special Issue Information

Dear Colleagues,

An intensification and acceleration of drought and flood phenomena on a planetary scale threaten the world’s water resources. Moreover, these phenomena could directly impact the quality and availability of water. Therefore, factories in the future will have to be economical and responsible.

Significant efforts have been developed in recent decades to reduce water consumption at the primary source, reuse or even recycle effluents after adequate purification treatments, and in some cases replace highly polluting technologies with less-polluting ones.

However, these examples are scattered and often inaccessible. The mission of this Special Issue, Water Use in Processing Industry, is to capitalize on and make accessible innovations in water saving at the plant level.

Authors are encouraged to submit papers focused on applications, methods, or tools that address the following:

#1 Reduction of water consumption by recycling or reuse with or without effluent treatment.
#2 Processing technologies that consume less water and pollute less.
#3 Clean and intelligent technologies to purify effluents.
#4 Comprehensive accounting of effects related to the reduction of water/recycling of effluents (LCA, economic study, etc.).
#5 Case studies specific to the processing industry (food industries, beverages, textiles, chemicals, pharmaceuticals, etc.).

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.

Brewer’s spent grains (BSG) are a significant by-product of beer production, and its improper disposal poses environmental challenges. This study investigated the use of BSG for activated carbon production with phosphoric acid as a chemical activator and its application in cheese whey remediation through liquid-phase adsorption. The adsorbent was thoroughly characterized through using techniques such as FTIR, SEM, N2 isotherms, and surface charge distribution. The adsorbent exhibited substantial pores, a high surface area (605.1 m2 g–1), good porosity, and positive surface charges that facilitated favorable interactions with cheese whey compounds. Equilibrium was achieved in 330 min for lactose, BOD5, and COD. The maximum adsorption capacities were 12.77 g g–1 for lactose, 3940.99 mg O2 g–1 for BOD5, and 12,857.92 mg O2 g−1 for COD at 318 K. Removing these adsorbates from cheese whey effluent reduces its organic load, enabling water reuse in the manufacturing unit, depending on its intended use. The adsorption process was spontaneous and endothermic, with ΔH° ≥ 265.72 kJ mol−1. Additionally, the activated carbon produced demonstrated impressive regeneration capability with sodium hydroxide, maintaining 75% of its adsorption capacity. These results emphasize the potential of activated carbon as an effective adsorbent for cheese whey remediation, providing a sustainable solution for waste management in the dairy industry and water reuse.
