Abstract
The treatment performance of a natural wetland (surface flow) was evaluate for the removal efficiency of Conductivity, Salinity, Turbidity, TS, TSS, TDS, TKN, NH4+-N, COD and BOD from municipal wastewater emanating from a southern locality of residential area in Ujjain, central India. These surface flow natural wetland had a rectangular size and covered in effective surface area of 1260 m2 (length 90 m x width 14 m) with a water retention capacity of 650 m3 approximately. The surface flow medium was composed of gravel/stone, soil and mud. Natural wetland support a dance and dominant vegetation of Cattail (TyphaLatifolia) in the Nullah bed throughout the year, TyphaLatifolia. Total plant of Cattail were 36540 (as average annual density 29 plants / m2 ) available and 6787 grams/m2 biomass of the plant recorded . The removal rate of Conductivity, (51.5%), Salinity (51%), Turbidity (65%), TS (61%), TSS (59%), TDS (63%), pH (7.3%), TKN (53%), NH4+-N (52.7%), COD (57%), and BOD (47.3%) were realized. An earthen channel provided initial pre-treatment by land treatment system. DO of effluent level increase to 74% indicating. It is indicating existing of aerobic condition in plant rooted bed. This SF system overall result established (A.) very cost effectively technology. (B.) SF removal efficiency above 50% for all parameters.
