INTRODUCTION
Phytorid technology is a type of constructive wetland system,
developed by National Environmental Engineering Research Institute
(NEERI), CSIR in 2005.Type of Decentralized waste water treatment
approach.Can be used for treatment of Domestic, Agricultural,
Slaughter house, Fish Pond water.Preferable for pre-treated sewage,
when sufficient land area is available.Combines Physical,
Biological and Chemical processes.

WORKING PROCESS OF PHYTORID TECHNOLOGY
ADVANTAGES OF PHYTORID BASED SEWAGE
SYSTEMSCost-effective.Operation and maintenance expenses are
negligible.Minimum electricity requirement, nearly fossil energy
free.Smaller footprint (Retention time: Typically less than 24
hrs). Facilitates recycle and reuse of water. No foul odour and No
Mosquito Nuisance.Tolerates fluctuations in operating conditions
such as flow, temperature and pH.
CONCLUSIONFrom the above discussion, it is concluded that
Phytorid technology is one of the efficient way of decentralized
treatment of water, requiring negligible operational and
maintenance cost, but more land area for higher volume of sewage.
Hence, it can be adapted in local societies and institutions.
Moreover, improvements should be further made to improve the
quality and efficiency of the phytorid system. The effluent water
can be used for irrigation, dilution, flush tanks etc.
