Acid mine drainage (AMD) is a significant threat to the environment due its high acidity and metal ion content. To effectively eliminate pollutants from AMD, various approaches are necessary. This review aims provide comprehensive understanding of recent advances in AMD mitigation. While treatment technologies have developed they often produce sludge as by-product require expensive maintenance. As cost-effective alternative, recovery resources can reduce toxicity promote reuse heavy metals rare earth elements. also analyzes challenges prospects mitigation implementation, including current conditions knowledge gaps. Researchers benefit this by gaining insight into research progress area, identifying strengths weaknesses applications, exploring future directions.

This study investigated the influence of hydraulic retention time (HRT) variation and presence macrophytes on efficiency two pilot-scale hybrid-constructed wetlands (HCWs) treating urban streamwater contaminated with nontreated sanitary sewage contributions from surrounding communities. Each HCW comprises a vertical unit (VF) horizontal (HF) filled sand gravel. HCW-P was planted withEichornia crassipes onto filtering media, HCW-C set up as control no macrophytes. The novelty this consists evaluating combination these factors (HRT macrophytes) in operation HCWs for removing organic matter nutrients. divided into step I, 9 days 133 days, II, an HRT 5 131 days. Neither (p-value = 0.7691) nor 0.0941) influenced COD removal, achieved high removal efficiencies (>87%) during operation. higher total nitrogen (TN) steps I II (56% 78%) compared to (31% 48%) operation, demonstrating improvement TN due ≤ 0.05). In addition, shorter promoted increase 22% longer enhanced ammonia (TAN) (46% 88%) than (29% 72%) respectively Regarding phosphorus (TP), 63% 89% 69% 96% confirming TP removal. Finally, demonstrated adaptability resilience operational conditions, even when fixed HCWs, which presented robustness nutrients via biofilm assimilation adsorption under variations.

Effective wastewater management is a critical environmental challenge, particularly in industrial regions like Faisalabad, where untreated textile effluents contribute to severe water pollution. This study evaluates the potential of phytoremediation using floating aquatic plants—Eichhornia crassipes (water hyacinth), Pistia stratiotes lettuce), and Lemna minor (common duckweed)—for treatment wastewater. A controlled laboratory-scale experiment was conducted assess pollutant removal efficiency over 10-day retention period. The initial effluent concentrations key parameters were measured before establish baseline conditions. results demonstrated that Eichhornia exhibited highest efficiency, achieving reductions 36.12% (TDS), 36.14% (EC), 36.30% (salinity), 6.12% (pH), 34.30% (total hardness), 44.52% (chloride). Furthermore, effective removing nitrate (99.76%), ammonium (52.11%), sodium adsorption ratio (46.29%), indicating species-specific potential. These findings highlight viability low-cost, eco-friendly, sustainable nature-based solution for clusters, offering practical alternative conventional technologies.
