“…Several physicochemical treatments such as electrochemical oxidation (Nhan & Luu, 2023), adsorption (Adegoke & Bello, 2015), coagulation-flocculation (Daud et al, 2023), and direct contact membrane distillation (Fortunato et al, 2021) have sufficiently removed the pollutants in textile wastewater. However, those techniques require high operational costs, engineering skills, high energy, and chemical demands (Crini & Lichtfouse, 2019;Moyo et al, 2022).…”

This research investigated the association of consortium endophyte bacteria from different hosts to enhance the performance of Vetiveria zizanioides in treating textile wastewater using Floating Treatment Wetlands (FTWs). The endophyte bacteria were isolated from the roots of three natural plants (Oryza sativa, Colocasia esculenta, and Alternanthera philoxeroides) contaminated by textile wastewater. The selected isolated endophyte bacteria were subjected to the four FTWs reactors containing the Vetiveria sp. and ran for 30 days in a semi-batch system to evaluate their performance. FTWs reactors-augmented endophyte bacteria could reduce the COD, color, and heavy metals in textile wastewater. The highest removal efficiencies of COD (74%) and color (91%) were observed in FK2 (vegetated control) and F4 reactor, respectively. The addition of endophyte bacteria increased the heavy metal reductions of Pb (52%) and Cd (33%) in reactors of F3 and F4, respectively. This study exhibited that the consortium endophyte bacteria isolated from the contaminated plants could improve the FTWs reactor performance. Finally, they reduce the plant stresses in the contaminated wastewater by increasing the plant biomass in roots and shoots. These findings reveal that the consortium of natural endophyte bacteria from different hosts does not inhibit their function and association with the other host plant, but they contribute positive responses to the plant growth and pollutant degradation.

“…Coagulation-flocculation is an important physicochemical process to purify a wastewater off impurities [1,2]. A coagulant, typically a short polymer termed often as a 'clarifying agent', neutralizes the particles' charge allowing them to coagulate.…”

Coagulation-flocculation, the physicochemical process widely used for purification a wastewater, is affected both by chemical details of involved polymers and by the statistics of their conformations on a large scale. The latter aspect is covered in this study by employing a coarse-grained modelling approach based on a combination of two paradigms of statistical mechanics. One is the self-avoiding walk (SAW) which generates a range of conformations for a linear polymer of $N_{{\rm SAW}}$ monomers. Another one is a non-trivial diffusion limited aggregation (DLA) process of $N_{{\rm DLA}}$ impurities (referred thereafter as ``particles") which describes their coagulation occurring with the probability $0< p \leq 1$ ($p=1$ recovers a standard DLA). DLA of diffusive particles is complemented by their irreversible adsorption on the SAW monomers occurring with the probability equal to one, both processes resulting in formation of the DLA-SAW agglomerates. The dynamics of formation of such agglomerates, as well as their fractal dimensions and internal structure are of practical interest. We consider a range of related characteristics, such as: (i) absolute $N_a$ and relative $n_a$ adsorbing efficiencies of SAW; (ii) effective gyration radius $R_{g {\rm DLA-SAW}}$ of the DLA-SAW agglomerates; and (iii) the fractal dimension $D_{{\rm DLA-SAW}}$ of these aggregates. These are studied within a wide range for each parameter from a set $\{p,N_{{\rm DLA}},N_{{\rm SAW}}\}$.
