Performance of Floating Constructed Wetland Reactors with Cyperus esculentus L. macrophyte at different Concentrations of Sewage

ABSTRACT The wastewater is contaminated with many impurities, referred as gray water due to mixing of fecal waste therefore it is necessary to treat the wastewater. The present investigation was aimed to develop a Floating Constructed Wetland Reactor system using Cyperus esculentus L.macrophyte for in situ on-site domestic sewage treatment. The sewage in its different concentrations was treated in batch systems designed with 120 saplings of Cyperus esculentus L. macrophyte planed in 5 rows and 6 columns with 4 saplings at each point planed in crates with inter bed of thermocol sheets, stone crushed aggregates. The results in terms of reduction in terms of TSS, TDS, TS, BOD, COD and nutrient contents indicate that the design fabricated is perfectly workable and capable to work at any of the concentrations and reduce the pollution load upto 80% within 35 days at 20% and 40% concentrations.
