SUBSURFACE FLOW CONSTRUCTED WETLANDS: REVIEW OF APPLICATIONS AND RECENT DEVELOPMENTSJAYA S. PILLAI AND BRIJESH NAIR A.N
Constructed wetlands are gaining importance as a sustainable technology for the decentralized treatment of wastewater. The potential for application of constructed wetland technology in developing countries is enormous, but the rate of adoption has been found to be very slow. The primary objective of this review is to present the current state of practice, range of applications, recent developments and researches in constructed wetlands and placing them in the overall perspective of the need for decentralized ecological sanitation systems. A brief summary of the principles of ecological sanitation is presented followed by definition, classification, and performance of subsurface flow constructed wetlands. Special emphasis is given to subsurface vertical flow constructed wetland systems considering the aspects of water reuse, nutrient reuse, biomass production and other ancillary benefits.
