The rapid expansion of both the global economy and human population has led to a shortage water resources suitable for direct consumption. As result, remediation will inexorably become primary focus on scale. Microalgae can be grown in various types wastewaters (WW). They have high potential remove contaminants from effluents industries urban areas. This review focuses recent advances WW through microalgae cultivation. Attention already been paid microalgae-based wastewater treatment (WWT) due its low energy requirements, strong ability thrive under diverse environmental conditions, transform nutrients into high-value compounds. It turned out that WWT is an economical sustainable solution. Moreover, different toxins are removed by biosorption, bioaccumulation, biodegradation processes. Examples agricultural runoffs textile pharmaceutical industrial effluents. mitigate carbon dioxide make use micronutrients present paper highlights application pollutants commonly mechanisms, simultaneous resource recovery, efficient co-culturing systems along with bottlenecks prospects.

Rapid industrialization, mine tailings runoff, and agricultural activities are often detrimental to soil health can distribute hazardous metal(loid)s into the environment, with harmful effects on human ecosystem health. Plants their associated microbes be deployed clean up prevent environmental pollution. This green technology has emerged as one of most attractive acceptable practices for using natural processes break down organic contaminants or accumulate stabilize metal pollutants by acting filters traps. review explores interactions between plants, microbiomes, discusses how they shape assembly plant-associated microbial communities modulate remediation. Here, we also overview microbe–heavy-metal(loid)s discuss bioremediation plants advanced phytoremediation properties approaches that have been successfully used, well biological processes. We conclude providing insights underlying remediation strategies’ mechanisms, key challenges, future directions metal(loid)s-polluted soils environmentally friendly techniques.

Pharmaceuticals in the Aquatic Environment: A Review on Eco-Toxicology and the Remediation Potential of Algae

International Journal of Environmental Research and Public Health, Год журнала: 2022, Номер 19(13), С. 7717 - 7717

Опубликована: Июнь 23, 2022

The pollution of the aquatic environment has become a worldwide problem. widespread use pesticides, heavy metals and pharmaceuticals through anthropogenic activities increased emission such contaminants into wastewater. Pharmaceuticals constitute significant class can seriously threaten health non-target organisms. No strict legal regulations on consumption release water bodies have been implemented global scale. Different conventional wastewater treatments are not well-designed to remove emerging from with high efficiency. Therefore, particular attention paid phycoremediation technique, which seems be promising choice as low-cost environment-friendly treatment. This technique uses macro- or micro-algae for removal biotransformation pollutants is constantly being developed cope issue contamination. aims this review are: (i) examine occurrence in water, their toxicity organisms describe inefficient treatments; (ii) present cost-efficient algal-based techniques contamination removal; (iii) characterize types algae cultivation systems; (iv) challenges advantages phycoremediation.

Hexavalent chromium ion removal from wastewater using novel nanocomposite based on the impregnation of zero-valent iron nanoparticles into polyurethane foam

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

Опубликована: Март 5, 2024

Abstract In this study, we developed a novel nanocomposite, polyurethane foam impregnated with zero-valent iron nanoparticles (PU@nZVI), for the effective removal of chromium(VI) from various water sources. The characterization nanocomposite (PU@nZVI) was performed by XRD, SEM–EDS, TEM and FT-IR techniques. Using response surface methodology, optimized conditions, achieving an optimal pH 2 dose 0.5 g/L. PU@nZVI demonstrated excellent maximum adsorption capacity 600.0 mg/g Cr 6+ . kinetics isotherms were best described pseudo-second-order model Freundlich isotherm, respectively. Significantly, removed 99.98% tap water, 96.81% industrial effluent, 94.57% treated sewage wastewater. Furthermore, maintained its efficiency over five adsorption–desorption cycles, highlighting reusability. These results suggest that is highly efficient sustainable option in treatment applications.
