Table-scale Floating Constructed Wetland (FCW) Reactor systems were constructed to operate in a batch mode and evaluate the rates of treatment at various concentrations of sewage. Cyperus esculentus L. macrophyte species were transplanted, acclimatized to sewage and then subjected to treatment using municipal sewage at 20%, 40%, 60%, 80% and 100% test concentrations with a set of control for comparison. The sewage samples were characterized before, periodically at the interval of 7 days and after the treatment for 35 days for pollution reduction rates in each set. It is seen observed that systems are capable in reducing the pollution load at all the concentrations of sewage evidenced by the reduction in characteristics like TDS, TSS, BOD and COD and nutrient contents to the considerable extent. Maximum reduction in terms of TSS (78.70%) in 20% sewage concentration, TDS by 79.45% in both, 20% and 40% sewage concentrations, BOD by 83.33% in 20% sewage concentration and COD (81.16%) in 20% sewage concentration along with considerable reduction in nitrates, phosphates, sulphates and chlorides. Studies revealed that the Floating Constructed Wetland Reactor (FCWR) systems are suitable for sustainable phyto-remediation of sewage with no operating costs; low maintenance costs and enhances the landscape with ecofriendly environment.
