Consider the following statements regarding Phytorid Technology develo...
CSIR-NEERI's technology involves a constructed wetland exclusively designed for the treatment of municipal, urban, agricultural, and industrial wastewater. The system is based on specific plants, such as Elephant Grass (Pennisetum purpureum), Cattails (Typha sp.), Reeds (Phragmites sp.), Cannas pp. and Yellow flag iris (Iris pseudocorus), which are normally found in natural wetlands with filtration and treatment capability. Some ornamental and flowering plant species, such as Golden Dhuranda, Bamboo, Nerium, Colosia, etc., can also be used for treatment and landscaping purposes. So, Statement 1 is correct.
It uses certain specific plants that can absorb nutrients directly from wastewater but do not require soil. These plants act as nutrient sinkers and removers. Using Phytorid Technology for the treatment of sewage, it is possible to recover and reuse the treated water for gardening purposes For the treatment of wastewater generated in the form of: Municipal/ Domestic wastewater Commercial establishments Agricultural runoffs Stormwater runoff So, Statement 2 is not correct.
Phytorid Technology is a combination of physical, biological, and chemical processes. It is a technology based on gravity that requires less energy. Phytorid Technology can be built into a series with modules / related cells depending on land availability and the amount of wastewater to be treated in groundwater.
So, Statement 3 is correct.
