The removal of hazardous and life-threatening integrated effluents from contaminated water is a major trepidation, the remediation process obtains reclaimed potable sparkling water, where Geopolymer arose as foremost effectual substance. Geopolymer-based materials are representatives massive group inorganic amorphous aluminosilicate with versatile industrial applications, they have been recently developed an ideal adsorbent owing to their chemical physical stability well skeletal network structure presence terminally negative charged ions porous nature along large surface area ∼292.05m2g-1 efficiency 98% for mesoporous geopolymer. Geopolymer, mainly derived raw products like Metakaolin Fly-ash, frequently employed adsorbents removing toxic heavy metals, dyes, radioactive nuclides. current scientometric assessment aims properly comprehend evaluate potential wastewater thoroughly through various techniques such adsorption, immobilization, encapsulation using geopolymer-based materials. Advanced fabrication 3D Printing, spin-coating, phase inversion, detailed mechanism introduction isotherms, kinetic models, regeneration ability, also explained.

Military operations over large areas of Ukraine lead to release explosives and their derivatives into the environment with subsequent accumulation in natural artificial water bodies, which unwittingly serve as reservoirs for collecting pollutants from catchment area. The need restore aquatic ecosystems dictates search efficient, cost-effective environmentally friendly methods elimination explosives, corresponds processes biological treatment. In this work, we examined ability common freshwater algae genus Rhizoclonium detoxify 2,4,6-trinitrotoluene (TNT) under model conditions pollution (at a TNT concentration 100 mg/L). exposure time was 48 hours, during content nitrites aqueous medium monitored, well chlorophyll activity glutathione S-transferase plant tissues. extracted toluene, followed by separation separatory funnel, removal residual sodium sulfate, reduction extract volume using rotary evaporator. decrease TNT, established GC-MS technique, 66.4% end experiment, while increased almost 15-fold. cells, threefold increase enzymatic observed already second hour exposure, gradual maintenance at level 50% control until experiment. total significantly sixth experiment due an b. results obtained indicate efficient biodegradation process prospects cleaning bodies contaminated TNT.

State-of-the-art microalgae-based bioreactor wastewater treatment for the elimination of emerging contaminants: A mechanistic review

Cleaner Water, Год журнала: 2024, Номер 2, С. 100027 - 100027

Опубликована: Июль 14, 2024

The review article explores the state-of-the-art advancements in using bioreactors based on microalgae to detoxify wastewater, with an emphasis removal of various environmental contaminants (VECs). Because their persistence and capacity for bioaccumulation, these pollutants—which include nutrients, heavy metals, organic compounds, microplastics, Polycyclic Aromatic Hydrocarbons (PAHs), emerging contaminants—pose serious threats environment human health. Innovative solutions are required since traditional wastewater treatment procedures frequently fail efficiently eradicate VECs. carefully looks at how well can break down remove VECs from wastewater. It clarifies numerous processes, including as biosorption, biotransformation, by which aid elimination pollutants. Contaminants be ingested microalgae, then metabolise them into less toxic compounds or incorporate biomass. This study examines adding methods improve both overall effectiveness operational stability. Operational challenges such maintaining optimal growth conditions scalability bioreactor systems, need continuous monitoring control thoroughly discussed. analysis highlights several avenues future research, genetically modifying strains enhance pollutant degradation, creating more effective designs, incorporating cutting-edge systems. indicates that although microalgae-based have great potential VECs, further investigation developments technology needed fully realise this large-scale applications. Researchers, engineers, politicians benefit greatly review, offers a thorough grasp present applications treatment.
