Ekta Chaudhary, Praveen Sharma

Treatment of domestic wastewater, at both the village and urban level, remains a problem in most developing countries. This is a review paper illustrating the use of duckweed-based wastewater treatment systems that provide genuine solutions to these problems. They are inexpensive to install as well as to operate and maintain. They do not require expensive technologies. Therefore, this review paper is oriented towards cost-effective and eco- friendly technology for waste water purification, which will be beneficial for community. This paper discusses the utilization of duckweed plants in purifying water and waste. They are functionally simple, yet easy to maintain; and they can provide tertiary treatment performance equal or superior to conventional wastewater treatment systems now recommended for large scale operation.
