Applied Water Science, Год журнала: 2021, Номер 11(6)

Опубликована: Май 28, 2021

Abstract Oily wastewater consists of fats, oils and greases together with a broad spectrum dissolved organic and/or inorganic substances in suspension. It is regarded as one the most hazardous wastewaters, causing serious environmental health threats to ecosystems, flora fauna. The global increase discharge oily coupled stringent regulations for effluent incessant drive re-use treated necessitate need treatment wastewater. Conventional approaches employed past are inept due low efficiency high operational costs, among others, hence adoption advanced technologies promising alternatives existing systems Furthermore, use combined processes effective removal pollutants present high-strength This review provides insights into emerging state-of-the-art safe efficient industrial

Electrocoagulation process for oily wastewater treatment and optimization using response surface methodology

International Journal of Environmental Science and Technology, Год журнала: 2023, Номер 20(12), С. 13859 - 13872

Abstract Electrocoagulation technique using aluminum electrodes in a batch bi-polar system was investigated to determine the efficiency of removing oil from oily wastewater. The Box–Behnken design utilized optimize conditions and effects four independent factors, including volume ( X 1 ), temperature 2 initial pH 3 treatment time 4 ),—were examined investigate turbidity recovery conductivity changes. significant variables their interactions were assessed ANOVA. optimal operating for removal obtained at an 10 ml L −1 , 28 °C, 4, coagulation 90 min. results revealed that changes are enhanced significantly with increasing decreasing volume. application process under allows promising efficiencies 97.3%, 73.4% conductivity, respectively. Also treated wastewater showed remarkable main pollution loads COD, NO PO DO, BOD. economic study indicated by electrocoagulation is very cost-effective technique.

Pollution Biomarkers in the Framework of Marine Biodiversity Conservation: State of Art and Perspectives

Water, Год журнала: 2021, Номер 13(13), С. 1847 - 1847

Опубликована: Июль 2, 2021

Marine biodiversity is threatened by several anthropogenic pressures. Pollution deriving from the discharge of chemical contaminants in sea represents one main threats to marine environment, influencing health organisms, their ability recover homeostatic status, and turn endangering biodiversity. Molecular cellular responses pollutants, known as biomarkers, are effect-based methodologies useful for detecting exposure assessing effects pollutants on biota environmental monitoring. The present review analyzes discusses recent literature use biomarkers framework conservation. study shows that pollution can be tools monitoring assessment threat biodiversity, both quality protected areas status species at risk. Moreover, key research need further development suggested, such omics-based specifically addressed conservation purposes validation field, extension biomarker a wider number endangered species, organic guidelines application approach support policies management.

Thermal conversion of irradiated LLDPE waste into sustainable sponge-like compounds: a novel approach for efficient trace-level oil–water removal

Scientific Reports, Год журнала: 2024, Номер 14(1)

Опубликована: Фев. 28, 2024

Abstract The newest method for recycling waste linear low-density polyethylene (LLDPE) is the thermo-catalytic degradation technique known as catalytic pyrolysis. Typically, it limited by 500–800 °C high temperatures. Catalytic pyrolysis releases toxins and forms harmful carbonized char. current study based on exposing wasted LLDPE to different gamma irradiation doses then in castor oil (150–300 °C). output product of Ir-(rLLDPE) turned into another compound with a new structural architecture (sponge-like). SEM analysis confirms conversion, showing sponge-like spicules layers. soft, malleable, absorbent texture. DSC demonstrates altered thermal properties, melting point at 121 splitting two peaks (endothermic 117 exothermic 160 signify curing process material. assessed an adsorbent aqueous oils solvents. examines doses, temperature, time capacity. removal obeys Langmuir isotherm monolayer adsorption, maximum adsorption capacity 24.75 g/g 43 1,1,2,2-tetrachloroethane.

Spatial Distribution and Influencing Factors of Chlorophyll a in Lianzhou Bay, Guangxi Province, China

Environments, Год журнала: 2025, Номер 12(2), С. 50 - 50

Опубликована: Фев. 4, 2025

Phytoplankton is essential in coastal marine ecosystems, aiding ecosystem stability and development of economy. Coastal as a transitional zone, feature complex, variable environmental factors that significantly affect phytoplankton growth. To assess the influencing growth bay area, this study measured chlorophyll (Chla), nutrients, four antibiotics (sulfamethoxazole, sulfadiazine, ciprofloxacin, enrofloxacin) seawater, well total nitrogen phosphorus contents sediments at 25 stations Lianzhou Bay. Principal component analysis risk quotient (RQ) were utilized for assessment. The results indicate Chla concentrations are inconsistent between nearshore offshore areas Specifically, abundant high ammonia levels, low enrofloxacin primary contributing to area. In contrast, hydrodynamic conditions, feeding by cultured shellfish, adequate lighting collectively shape distribution characteristics Additionally, ecological posed relatively low. findings provide scientific evidence local management pollution sources optimization aquaculture models, which great significance sustainable utilization resources.
