Ecological floating beds are effective in mitigating lake eutrophication. To examine the effects of their situ remediation processes on food sources and trophic structures consumers, particularly fish, this study used stable isotope techniques to compare cage enclosures, net natural area Meiliang Bay, Lake Taihu. The results revealed that among basic carbon sources, only δ13C values phytoplankton POM differed significantly, while most consumers showed no significant differences nitrogen characteristics across three areas. In chain transitioned from being grazing-based, dominated by phytoplankton, detritus-based, primarily relying SOM. contrast, enclosures enhanced utilization phytoplankton. levels were significantly lower than those area. Trophic niche indices indicated exhibited highest diversity lowest redundancy. using ecological altered resource conditions within areas due degree enclosure provided interception facilities. These changes have consequently reshaped internal structure through cascade effects.

Nature-Based Solution for Wastewater Treatment and Reuse Using Phytoremediation with Floating Plants

Water, Journal Year: 2025, Volume and Issue: 17(7), P. 1080 - 1080

Published: April 4, 2025

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.
