Phytorid

The traditional treatment systems of sewage and other waste water have used conventional technologies which are prone to high wear and tear of the system leading to substantially high O&M costs. Phytorid Technology can treat the wastewaters by naturally without the addition of chemicals. It has been accomplished with the use of aquatic or semi aquatic plants along with their associated biota. It is an improved wetland ecosystem for treatment of wastewater. It involves proper utilization of biological treatment capacity with optimized engineering parameters.

The ‘Phytorid Technology’ developed and tested by CSIR-NEERI has also been patented in India and abroad. It is an innovative natural treatment system for treatment of sewage naturally. It is one of the technology marvel which is being used increasingly for various types of biodegradable waste water across India. It is a combination of the physical, chemical and biological processes which results into ultimate treatment for the waste water. This particular technology works without electricity, minimum maintenance, less manpower and importantly self-sustainable.

Conventional STP plants cannot remove pollutants like nitrates and phosphates which penetrate the groundwater and pollute it, but Phytorid does the job. Phytorid also removes the fecal coliform from wastewater.

A Phytorid system is an artificial wetland created for the purpose of treating municipal or industrial wastewater, grey water or stormwater runoff. It may also be created for land reclamation after mining, refineries, or other ecological disturbances such as required mitigation for natural areas lost to land development. Constructed wetlands are engineered systems that use natural functions of vegetation, soil, and organisms to treat different water streams. Depending on the type of wastewater that has to be treated the system has to be adjusted accordingly which means that pre- or post-treatments might be necessary. Constructed wetlands can be designed to emulate the features of natural wetlands, such as acting as a bio-filter or removing sediments and pollutants such as heavy metals from the water. Some constructed wetlands may also serve as a habitat for native and migratory wildlife, although that is usually not their main purpose. In this technology, treatment occurs via natural methods such as filtration, sedimentation nutrient uptake by plants and microbial action in a constructed system which is filled with gravels. Specifically identified different species of plants which are known to have good nutrient uptake rates are planted in the gravel bed.
