The eligible studies were analyzed to extract data and information pertaining to the configuration of anaerobic reactors, operational parameters, and various pretreatment processes such as chemical, biological, enzymatic, thermal, microaerobic, and ultrasonic. The findings derived from this current review demonstrated that different chemical, biological, and physical pretreatment technologies improve the biomethane potential (BMP) and potentially affect the dominant bacteria and archaea. Moreover, although hydrogenotrophic methanogenesis are more observed due to resistance to extreme conditions, methane production follows both aceticlastic and hydrogenotrophic pathways in AD assisted with different pretreatment process. <i>Firmicutes</i> and <i>Bacteroidetes</i> phyla of bacteria were the dominant hydrolytic bacteria due to synergetic effects of different pretreatment process on solubilization and bioavailability of recalcitrant substrates.

Various agro-food waste materials, namely potato peelings (PP), rice cooking water (RW), biscuit by products (BB), carob pods (CP), and eggshells, were evaluated as nutrient sources for bacterial growth compared to a synthetic medium (SM). The results indicate that the medium comprising carob pods, potato peels supplemented with eggshells promoted the growth of the bacteria and the production of Biosurfactants at a rate of 150 mg/l and 140 mg/l respectively. The biosurfactant exhibited an emulsification index (E24) of 55.23 ± 0.32%, 46.47 ± 3% 43.80 ± 0.4%, 18.33 ± 0.25% and 20 ± 0.11% for PP, CP, SM, BB and RW respectively. The biosurfactant produced from PP had the ability to decrease the surface tension of water from 74 to 39.38 mN/m, with a critical micelle concentration (CMC) of 15 mg/L. The chemical characterization of purified biosurfactant was done using Fourier-transform infrared spectroscopy (FTIR) and Thermal gravity (TG), as well as differential scanning calorimetry (DSC) analysis (TG/DSC), revealing the functional groups and thermostability of the biosurfactant.

The continuous mutations of the virus variants have accelerated the demand for scientific research on disinfection techniques for a safer indoor environment. Among all the available surface disinfection techniques, ultraviolet germicidal irradiance at 254 nm wavelength has been proven for its disinfection efficacy; however, its usage is limited to unoccupied conditions due to the risk of ultraviolet exposure. This study investigated the efficacy of far-UVC-222 nm experimentally in both controlled environment and field setting. Staphylococcus epidermidis and Mycobacterium smegmatis were employed for surface disinfection in both the laboratory and a meeting room. Total plate count was used to determine the disinfection efficacy by a 20 W unfiltered far-UVC lamp. At 1.1 µW/cm² far-UVC irradiation, a 1-log₁₀ reduction of Staphylococcus epidermidis and Mycobacterium smegmatis contamination on tabletop can be achieved by 31.3 min and 101.8 min of far-UVC irradiation, respectively. Other pathogens of interest such as Staphylococcus aureus, Mycobacterium tuberculosis, Legionella pneumophila, SARS-CoV-2, and the Measles virus were also referred and compared in this study. This study carefully examined how far-UVC irradiation performs effectively for surface disinfection in a real meeting room setting. The results offer useful recommendations for alternatives to upper-room ultraviolet germicidal irradiance for continuous disinfection within the ultraviolet threshold limit value, with the goal of preventing the spread of any diseases in the future.</p></div>","PeriodicalId":628,"journal":{"name":"Journal of Environmental Health Science and Engineering","volume":"22 2","pages":"569 - 577"},"PeriodicalIF":3.0,"publicationDate":"2024-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141868967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Synchronously, with the development of this system, particularly, in concern with the littoral regions, seawater concentrate disposal consisting of various pollutants was taken into consideration. In this research, two desalination plants near each other were selected and four scenarios have been foreseen, for the discharge of seawater concentrate and the desalination intake, which are taken under study in the <i>Ramin-Chabahar</i> region, based on dual-dimensional hydrodynamic simulation, comprising of diffusion and release, by utilizing the MIKE 21 Software. Due to the proximity of the two desalination plants, to reduce the costs of piping in the sea, the location of discharge and intake were considered common. On the grounds pertaining to the modeling results, the discharge of seawater concentrates, at a distance of 300 m (5 m of depth) from the coast and the intake point, at a distance of 800 m, in elongation, has had the minimum environmental impact; as well as having no undesirable effect on the water quality of the intake, in addition to being cost-effective, from the economic viewpoint. To dilute seawater concentrate to a standardized level, it is appropriate to discharge through a diffuser with 10 nozzles, which are spaced out at 3.25 m from each other, being positioned linearly on one side, at an angle of 60 degrees. With the optimal selection of intake and discharge points of seawater concentrate in marine desalination plants, in addition to increasing the quality of treated water and reducing adverse environmental effects, construction and operation costs are also reduced.</p></div>","PeriodicalId":628,"journal":{"name":"Journal of Environmental Health Science and Engineering","volume":"22 2","pages":"555 - 567"},"PeriodicalIF":3.0,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141720287","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Industrial emissions often carry substantial dust content, necessitating the reduction of their environmental release. This study introduced a laboratory-scale photoelectric precipitator to assess its effectiveness in curbing particle emissions under varying temperature, humidity, and residence time conditions. This device operates in two stages: firstly, it charges particles by exposing copper wire surfaces to ultraviolet rays, generating photoelectrons in the airflow; secondly, it utilizes a positively charged collector surface for absorption and collection. Assessment under different temperature, residence time, and humidity conditions revealed that the system designed for 10 μm diameter particles displayed the highest efficiency. At 150℃, the removal efficiency was 39.55%, rising to 41.34% at 60% humidity and 43.58% with an 18-second residence time. Furthermore, increasing energy consumption from 144 j/l to 720 j/l resulted in a 10.93% efficiency increase, highlighting the correlation between energy input and system efficiency. High particulate matter levels diminish visibility, harm the climate, ecosystems, materials, and contribute to respiratory and cardiovascular ailments. These findings underline the photoelectric precipitator’s potential in mitigating particulate matter’s adverse effects on health and the environment. However, further research is warranted to optimize system design and explore additional parameters’ impact on performance, ensuring its effectiveness in industrial processes to reduce particulate matter emissions.</p></div>","PeriodicalId":628,"journal":{"name":"Journal of Environmental Health Science and Engineering","volume":"22 2","pages":"545 - 554"},"PeriodicalIF":3.0,"publicationDate":"2024-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141643528","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
