“…I. aquatica has a high economic value, compared with other hydrophytes. It has been used for heavy metals and organic pollutants adsorption, and agricultural wastewater treatment [17][18][19]. In the present study, the removal rates of TN and NH 4 + -N in I. aquatica floating bed was relatively high receiving high and low LPW.…”

“…Plants with more than one BCF and high root-to-shoot metal translocation, as displayed by brake fern (Pteris vittata), are ideal for phytoremediation and also relate to the plant to act as a hyper-accumulator (Pandey 2012;Hadi et al 2014). For instance, plant species like duckweed (Lemna gibba), water spinach (Ipomonea aquatica), and fern (Azolla pinnata) have been reported to phytoremediate metals like boron, chromium, and manganese, respectively (Marin and Oron 2007; Bharti and Banerjee 2012;Chen et al 2010).…”

This study investigates the effectiveness of aquatic macrophyte and microphyte for phytoremediation of water bodies contaminated with high arsenic concentration. Water hyacinth (Eichhornia crassipes) and two algae (Chlorodesmis sp. and Cladophora sp.) found near arsenic-enriched water bodies were used to determine their tolerance toward arsenic and their effectiveness to uptake arsenic thereby reducing organic pollution in arsenic-enriched wastewater of different concentrations. Parameters like pH, chemical oxygen demand (COD), and arsenic concentration were monitored. The pH of wastewater during the course of phytoremediation remained constant in the range of 7.3–8.4, whereas COD reduced by 50–65 % in a period of 15 days. Cladophora sp. was found to survive up to an arsenic concentration of 6 mg/L, whereas water hyacinth and Chlorodesmis sp. could survive up to arsenic concentrations of 2 and 4 mg/L, respectively. It was also found that during a retention period of 10 days under ambient temperature conditions, Cladophora sp. could bring down arsenic concentration from 6 to <0.1 mg/L, Chlorodesmis sp. was able to reduce arsenic by 40−50 %; whereas, water hyacinth could reduce arsenic by only 20 %. Cladophora sp. is thus suitable for co-treatment of sewage and arsenic-enriched brine in an algal pond having a retention time of 10 days. The identified plant species provides a simple and cost-effective method for application in rural areas affected with arsenic problem. The treated water can be used for irrigation
