Using Phytoremediation to Treat Industrial and Pharmaceutical Wastewater

Advances in environmental engineering and green technologies book series, Год журнала: 2025, Номер unknown, С. 277 - 298

Опубликована: Янв. 16, 2025

Phytoremediation is an economical, environmentally friendly and effective technology that uses plants to treat wastewater. This research focuses on phytoremediation of wastewater industrial pharmaceutical. Certain fresh plant species, such as Lemna minor, Salvinia minima, Ipomoea aquatica Centella asiatica, have been shown decontaminate environments. For example, these helped reduce total suspended solids (TSS) from 50.8% 85.6%, ammonia nitrogen (NH3-N) 79.1% 97.3% chemical oxygen demand (COD) 36.46% 82% in The exact results depend the type its operating time. In addition, microalgae Chlorella pyrenoidosa Scenedesmus almeriensis be highly removing heavy metals cadmium (57.14% just 3 hours) arsenic (40.7% hours). conclusion, a promising approach water treatment sector, particularly for pharmaceutical which heavily contaminated with complex toxic substances.

Green adsorbents for water remediation: Removal of Cr(vi) and Ni(ii) using Prosopis glandulosa sawdust and biochar

Green Processing and Synthesis, Год журнала: 2025, Номер 14(1)

Опубликована: Янв. 1, 2025

Abstract Potentially toxic elements like Cr +6 and Ni +2 cause severe health hazards. Therefore, the current work was aimed at cleaning water using Prosopis glandulosa raw sawdust (SD) its derived biochar (AC). Both adsorbents were characterized via SEM, FTIR spectroscopy, EDX, TGA applied for effective removal of Ni( ii ) Cr( vi optimum values experimental conditions, mechanism assessed adsorption isotherm kinetic models. The correlation coefficient R 2 confirmed pseudo-second-order kinetics preferred Freundlich model. Maximum iv obtained a pH 4.0, bio-sorbent concentration 0.8 g·L −1 , temperature 50°C 50 min with metal 110 ppm, while maximum contact time 70 130 ppm in above-mentioned conditions. results isotherms model revealed that processes involved multilayer formation on biosorbent’s heterogeneous surface. Also, their thermodynamic investigation showed process is spontaneous exothermic and, therefore, can be effectively utilized to remove from water.

Water pollution is a significant problem stemming from several causes, with the contamination of heavy metal(oid)s being primary concern. This especially concerning because poisonous characteristics these and their effects on aquatic ecosystem. research distinguished by its unique methodology for assessing in surface water Bangladeshi rivers over period sixteen years, 2007 to 2022. work seeks elucidate recent results metal(oid) concentrations, levels, multivariate statistical analyses, source identification using positive matrix factorization models, probabilistic health risks. The findings reveal that concentrations chromium, nickel, arsenic, cadmium, lead exceeded acceptable limits drinking established World Health Organization (WHO) factors 4.64, 2.25, 22.51, 45.60, 10.13, respectively. Our meta-analysis, subsequent Principal Component Analysis, indicated increased hazardous metals account 85.47% variation both anthropogenic natural causes. Ecological risk indicators, including metal index (84.06) Nemerow (10.55), contamination. like indicate substantial (PMF) model detected following sources water: industrial (22%), mixed (32%), agricultural activities (27%), (19%). Furthermore, Monte Carlo-simulation-based assessments hazards mean hazard (HI) cancer values adults (301.89 422.76) children (51.56 39.45) significantly recommended limits, suggesting are vulnerable potential non-carcinogenic carcinogenic immediate execution control measures regulations essential avert escalating water, protect ecosystems, mitigate hazards.
