Special Issue Information

Dear Colleagues,

Industrial wastewaters represent a main source of water pollution which severely affects our ecosystem. The problem comes from the wide range of contaminants generated by each type of industry, which affects the suitability and efficiency of treatment processes. The proper characterization of various industrial effluents followed by optimization of the suitable treatment process(es), considering the techno-economic and environmental aspects (including the potentials of recycling and energy/materials recovery), will enable us to efficiently deal with this issue.

The focus of this Special Issue on “Industrial Wastewater Treatment and Recycling” aims to collect up-to-date research articles that explore, examine, and make proposals for optimizing the treatment process(es) dealing with unconventional substrates. Particularly, we are interested in the potential of biological processes, as the most eco-friendly options (e.g., anaerobic digestion, anammox, microbial fuel cells, etc.), to eliminate organic contaminants and generate bioenergy and/or useful chemicals. This Special Issue will incorporate articles that present innovative techniques, analyses, and/or characterizations towards the better understanding/valorization of industrial effluents. We also interested in papers that cover impact assessment tools in terms of social, economic and environmental aspects either in point of use scale or global scale. Tools like life-cycle assessment and SDGs impact assessment give the readers indication about issues that must taking into consideration during the implication of the utilized treatment technology. In addition, we also welcome papers in the form of reviews and case studies.

The Guest Editors will select high-quality research papers to proceed with blind peer reviews. Reviewers will be selected among researchers who are active in the field, whose works are present in international databases.

Within the framework described above, this Special Issue invites authors to contribute papers addressing the following topics:

  • Contaminants in industrial wastewaters;
  • Toxicity;
  • Industrial wastewater treatment systems;
  • Wastewater recycling;
  • Integrated chemical-biological processes for wastewater treatment;
  • Bio-processes for methane and hydrogen production;
  • Bioenergy from lignocellulosic wastes;
  • Bio-processes to produce platform chemicals from wastes;
  • Nanomaterials for the promotion of microbial processes;
  • Bioelectrochemical systems (BESs);
  • SDGs impact assessment;
  • Life-cycle assessment.

Life cycle assessment (LCA) is a powerful tool to evaluate the environmental impacts of domestic wastewater treatment plant (WWTP) operations. It involves a thorough evaluation of the main characteristics or components of the environment, human health, and resources. However, the literature to date is still lacking analysis on the widely varied designs and operational conditions of full-scale WWTPs. The aim here was to integrate analyses such as LCA, greenhouse gas (GHG) emissions, and energy consumption, when considering the environmental impacts of a full-scale WWTP, which can provide practical outputs to aid decision-making on optimum designs and operational conditions. The Russtmiya domestic WWTP, located in Iraq, was considered as the case study. Three operational alternatives were proposed as solutions to improve the WWTP’s performance, as follows: (1) conventional activated sludge with sand filter (CAS), (2) conventional activated sludge with sand filter and nitrogen removal (CAS-N), and (3) membrane bioreactor (MBR). The operation of such alternatives was investigated through modeling and simulation using GPS-X 8.0.1 software. The energy consumption of each alternative was estimated via GPS-X, while the GHG emissions were estimated using three different methods according to the intergovernmental panel on climate change (IPCC), the United States Environmental Protection Agency (USEPA), and GPS-X software. The OpenLCA software (1.10.3) was used to measure all impact categories at both the midpoint and endpoint levels using various methods. As a conclusion, comparing the three proposed alternatives indicated that: (1) the MBR alternative provided the lowest energy consumption and moderate GHG emissions, and (2) the CAS alternative provided the best environmental performance, particularly in aspects such as ozone depletion, global warming, and climate change, where the lowest GHGs emission values had the major contribution.

Irrigation with reclaimed water is a widespread solution to coping with water scarcity, especially in the Middle East and North Africa (MENA) region. This paper presents a systematic evaluation approach of six treatment alternatives proposed for Alexandria WWTP in Egypt as an applied example. This approach evaluates the effluent quality and cubic meter price from the proposed treatment alternatives while managing the health risks associated with reclaimed water irrigation. Rotavirus, Salmonella, Giardia duodenalis, and Ascaris were studied as waterborne pathogens. A quantitative microbial risk assessment model was used for the estimation of annual infection risks. The exposure scenarios include farmers and vegetable consumers. Activated sludge provided the lowest costs; however, it gave the lowest efficiencies and highest health risks. On the other hand, the highest efficiency and lowest health risks were obtained by the membrane bioreactor. The resulting price of a cubic meter of treated wastewater, used in irrigation, ranged from 0.082 to 0.133 USD. Irrigation using tertiary-treated wastewater achieved the target infection risk for unrestricted irrigation without using advanced treatment facilities. The results of this study could give a comprehensive view of reusing wastewater to decision-makers to address both water and food poverty not only in Egypt but also in other countries in MENA with similar economic and agro-ecological conditions.

Dye solution temperature influences the elimination efficiency of water-soluble and anionic acid dye. Acid Blue 25 dye, using a gas–liquid electrical discharge system, was successfully investigated. The results showed an increase in the percentage of dye decolorization from 91.16% to 96.12% when the dye solution temperature was increased from 278 K to 308 K. However, the initial dye decolorization percentage was decreased with the further increase in dye solution temperature from 318 K to 358 K. The 2D simulation model was introduced to consider the influence of temperature and the electric field generated by corona discharge plasma in air and water. Results also showed a great match between the experimental and the simulation results. The reaction rates of dye degradation were analyzed using the Arrhenius equation. Furthermore, pseudo-zero-, pseudo-first-, and pseudo-second-order models were used to determine the reaction kinetics. The best fit for the experimental data would follow the pseudo-first-order model. Finally, electrical energy per order, energy yield, and experimental degradation data were calculated to investigate the cost analysis. Full article

Currently, the population is experiencing severe water stress mainly due to high water consumption by industries. Food and beverage processing consumes up to 90% of freshwater, resulting in large volumes of wastewater that is often treated with complex, costly and environmentally damaging processes. The purpose of this study is to perform the first bibliometric analysis to evaluate and discuss the evolution in the use of environmentally friendly technologies for wastewater treatment in food processing plants. A total of 606 documents published up to August 2022 were retrieved from Scopus. Data were manually standardized. VOSviewer version 1.5.18 and Bibliometrix version 4.0.0 were used to perform scientific mapping and evaluate bibliometric indicators of quantity, quality and structure. Scientific production is growing exponentially due to factors such as strict environmental policies and increased environmental awareness. The average number of authors per document is 4.056 and prolific authors in the field have not yet been defined. The contribution of the countries (led by the United States with 104 documents) was associated with their gross domestic product (GDP), level of trade and industrialization. Likewise, institutions from China (third place with 70 documents) have the highest contribution in the field. On the other hand, most of the journals where the documents were published are of high quality according to different metrics. According to the most influential articles, the frequency of keywords and their dynamics over time, the use of microalgae, microorganisms and plants for the treatment of effluents generated during food processing is the main trend. The processes also focus on the recovery or recycling of compounds of interest in wastewater such as phosphorus, nitrogen and carbon to contribute to the circular economy. Full article

The rising concentration of global atmospheric carbon dioxide (CO2) has severely affected our planet’s homeostasis. Efforts are being made worldwide to curb carbon dioxide emissions, but there is still no strategy or technology available to date that is widely accepted. Two basic strategies are employed for reducing CO2 emissions, viz. (i) a decrease in fossil fuel use, and increased use of renewable energy sources; and (ii) carbon sequestration by various biological, chemical, or physical methods. This review has explored microalgae’s role in carbon sequestration, the physiological apparatus, with special emphasis on the carbon concentration mechanism (CCM). A CCM is a specialized mechanism of microalgae. In this process, a sub-cellular organelle known as pyrenoid, containing a high concentration of Ribulose-1,5-bisphosphate carboxylase-oxygenase (Rubisco), helps in the fixation of CO2. One type of carbon concentration mechanism in Chlamydomonas reinhardtii and the association of pyrenoid tubules with thylakoids membrane is represented through a typical graphical model. Various environmental factors influencing carbon sequestration in microalgae and associated techno-economic challenges are analyzed critically. Full article

The aim of this review is to investigate a kind of process intensification equipment called a rotating packed bed (RPB), which improves transport via centrifugal force in the gas–liquid field, especially by absorption. Different types of RPB, and their advantages and effects on hydrodynamics, mass transfer, and power consumption under available models, are analyzed. Moreover, different approaches to the modeling of RPB are discussed, their mass transfer characteristics and hydrodynamic features are compared, and all models are reviewed. A dimensional analysis showed that suitable dimensionless numbers could make for a more realistic definition of the system, and could be used for prototype scale-up and benchmarking purposes. Additionally, comparisons of the results demonstrated that Re, Gr, Sc, Fr, We, and shape factors are effective. In addition, a study of mass transfer models revealed that the contact zone was the main area of interest in previous studies, and this zone was not evaluated in the same way as packed beds. Moreover, CFD studies revealed that the realizable k-ε turbulence model and the VOF two-phase model, combined with experimental reaction or mass transfer equations for analyzing hydrodynamic and mass transfer coefficients, could help define an RPB system in a more realistic way.
