“…The retention time used in the study was 9 h, which was shown to be sufficient to remove arsenic from the influent water and the effluent could be safely discharged into a natural reservoir. Jenssen et al [7] have used CW to remove divalent metals, such as copper, lead, and zinc, and more recently Nemade et al [22] employed constructed soil filter that results in oxidation of As (III) to As (V) and co-precipitation by iron salt and removal of arsenic below WHO standard. Despite the high efficiency of the wetland system to remove arsenic, the wastes must be treated as hazardous as they accumulated the toxic metal.…”

“…Zhang et al, (2007) [25] have reported 94.5% COD removal from wastewater in a soil infiltration treatment. Nemade et al, (2009) [26] gives 94% COD removal in the performance of a constructed soil filter plant at Worli, Mumbai, India. Similarly, Foladori et al, (2012) [27] report 82% COD removal in a vertical flow filter, which constitutes the first stage of a hybrid constructed wetland.…”

In this work, an innovative arrangement of a vertical subsurface flow wastewater infiltration system (SWIS) was studied. The principal objective of this study was to evaluate the oxygen transfer rate (OTR) in two different pilot-scale arrangements of an SWIS. The two pilot plants were composed of four filter beds in series, one with a vertical arrangement of the beds (one over the other) and the other with a horizontal arrangement of the beds (one next to the other). Furthermore, two kinetic models were applied for correlating the COD and NH4+-N concentrations at the inlet and outlet of each treatment step in both pilot plants. The fitting of experimental data to the models allowed the calculation of the areal rate constants. The OTR values obtained were 54.69 g m−2 h−1 and 28.84 g m−2 h−1 for horizontal and vertical arrangement, respectively. These values were considerably higher than those obtained by other authors. The plug flow model describes the behaviour of these SWISs better, and the best fits were achieved for the vertical arrangement. The areal rate constant values obtained in this study were higher than those reported in the bibliography, which indicates a great removal efficiency and therefore lower surface area needed for the treatment.

The growth of industry leads to the contamination of surface as well as groundwater. Improper industrial wastewater disposal causes a serious problem of metal accumulation in the soil and freshwater. To tackle this issue there is a need of recycling and reuse wastewater using low-cost sustainable treatment. The main objective of this research is to check the feasibility of multimedia vermifilter for the efficiency removal of physicochemical parameter and fluoride metal ions of fluoride-tented used water (wastewater). For the treatment, we used fluoride contaminated used water (wastewater) from the fluoride contaminated site. In this study multimedia vermifilter integrated with moringa seed extract, activated charcoal powder, and earthworm Eisenia fetida were used as bio-media to treat contaminated used wastewater, In this experimental analysis, we checked the removal efficiency on different HLR in m3/day/m2. The result showed that percentage removal efficiency for BOD, COD, TDS and Fluoride using inverted multimedia filter was observed for the optimized hydraulic loading rate at 0.933m3/day/m2 was found to be BOD (81.64%), COD (51.47%), TDS (82.17%), Fluoride (35.81%) respectively. The earthworm, moringa seed extract, and activated charcoal play a vital role in the removal of Bioconversion of organic matter. Furthermore Treated effluent waste-water is then used for gardening and irrigation purposes.
