Abstract
Stormwater runoff originating from agricultural fields, garden, green belts, parks, etc. is susceptible to carry along phosphate in dissolved form in it. Presence of phosphate can lead to eutrophication in water the receiving bodies even if its concentration is < 0.1 mg/l. Natural or cultural eutrophication has led to significant adverse effect on water quality around the globe. The present study was undertaken to determine the efficacy of Phragmites based constructed wetland for the removal of phosphate from stormwater runoff under Indian conditions. The study was conducted under natural environmental conditions to evaluate the role of meteorological parameters. It was observed that Phragmites based wetland could efficiently remove the phosphate from stormwater with an efficiency as high as 96% at hydraulic retention time (HRT) of 24 h. The increase in ambient temperature increases the phosphate removal efficiency of sp. It leads to the conclusion that Phragmites removes phosphates from synthetically prepared stormwater runoff in a CW cell which it is a sustainable and eco-friendly technique to remove phosphate from stormwater runoff. This process does not require energy from external source is required for its operation.
