Environmentally Friendly Technologies for Wastewater Treatment in Food Processing Plants: A Bibliometric Analysis

et al. 2022

View full text Add to dashboard Cite

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.

“…Understanding this process and the effects of storage duration can facilitate the development of sustainable treatment methods and mitigate its adverse environmental effects (Jarboui et al, 2023). Storage duration has been identified as a significant factor influencing the polyphenolic composition, and comprehending these changes is vital for optimizing the storage process and maximizing the beneficial properties of OMW (Lozada et al, 2022).…”

This study investigated the impact of storage duration on olive mill wastewater (OMW) quality and biological properties. Among two various olive varieties, Abani exhibited the highest phenolic compound concentration after 12 months of storage. Liquid chromatography-mass spectrometry (LC-MS) analysis identified 28 OMW constituents, with kampherol as the major one, and rosmarinic acid detected for the first time. Results showed significant differences in antioxidant and anti-inflammatory activities among samples. The inhibition of protein denaturation (IPD) test yielded the best value after 1 month for Abani OMW, while membrane-stabilizing potential (MSP) test values were highest after 12 months for the same variety. Anticoagulant activity, measured by activating partial thromboplastin time (APTT) and prothrombin time (PT), significantly varied with storage time, with the most favorable values found in Zlitni OMW immediately after olive oil extraction. These findings illuminate OMW changes over time, bearing significance for OMW management and potential applications.

“…It provides a way of selecting a few points in the design space to efficiently represent the experimental space and, in that way, reduces the number of experimental runs for investigating the factor influences and interactions between them on the selected response. RSM was successfully applied in several subject areas connected to membrane processes, such as membrane synthesis optimization [ 26 , 27 ], optimization of chemical cleaning [ 28 ] and membrane performance [ 29 , 30 , 31 , 32 ].…”

Kenics Static Mixer Combined with Gas Sparging for the Improvement of Cross-Flow Microfiltration: Modeling and Optimization

et al. 2022

View full text Add to dashboard Cite

The use of membrane filtration as a downstream process for microbial biomass harvesting is hampered due to the low permeate flux values achieved during the microfiltration of fermentation broths. Several hydrodynamic methods for increasing permeate flux by creating turbulent flow patterns inside the membrane module are used to overcome this problem. The main goal of this study was to investigate the combined use of a Kenics static mixer and gas sparging during cross-flow microfiltration of Bacillus velezensis IP22 cultivation broth. Optimization of the microfiltration process was performed by using the response surface methodology. It was found that the combined use of a static mixer and gas sparging leads to a considerable increase in the permeate flux, up to the optimum steady-state permeate flux value of 183.42 L·m−2·h−1 and specific energy consumption of 0.844 kW·h·m−3. The optimum steady-state permeate flux is almost four times higher, whilst, at the same time, the specific energy consumption is almost three times lower compared to the optimum results achieved using gas sparging alone. The combination of Kenics static mixer and gas sparging during cross-flow microfiltration is a promising technique for the enhancement of steady-state permeate flux with simultaneously decreasing specific energy consumption.
