Phytorid<br />

Phytorid is a technology that <strong>in</strong>volves a constructed wetland<br />

exclusively designed for the treatment <strong>of</strong> municipal, urban,<br />

agricultural and <strong>in</strong>dustrial wastewater. It has been developed by<br />

National Environment Eng<strong>in</strong>eer<strong>in</strong>g & Research Institute (NEERI).<br />

The system is based on the specific plants, such as Elephant grass<br />

(Pennisetum purpurem), Cattails (Typha sp.), Reeds (Phragmites<br />

sp.), Canna sp. and Yellow flag iris (Iris pseudocorus), normally found<br />

<strong>in</strong> natural wetlands with filtration and treatment capability. Some<br />

ornamental as well as flower<strong>in</strong>g plants species can also be used for<br />

treatment as well as for landscap<strong>in</strong>g purposes.<br />

The phytorid technology can be constructed <strong>in</strong> series and parallel<br />

modules / cells depend<strong>in</strong>g on the land availability and quantity <strong>of</strong><br />

wastewater to be treated.<br />

The phytorid technology treatment is a subsurface flow type <strong>in</strong> which<br />

wastewater is applied to cell / system filled with porous media such<br />

as crushed bricks, gravel and stones. The hydraulics is ma<strong>in</strong>ta<strong>in</strong>ed <strong>in</strong><br />

such a manner that wastewater does not rise to the surface reta<strong>in</strong><strong>in</strong>g<br />

a free board at the top <strong>of</strong> the filled media.<br />

The system consists <strong>of</strong> the follow<strong>in</strong>g three zones:<br />
