Constructed wetland is an engineered system that attains more attention as a feasible technology for treatment of municipal landfill leachate. This study aimed to find the efficiency of Hybrid constructed wetland system for treatment of landfill leachate. Landfill leachate taken from a landfill situated in Uttan, under Mira-Bhayander Municipal Corporation is to be treated in a laboratory scale hybrid constructed wetland (HCW) which consist of horizontal sub-surface flow constructed wetlands (HSSFCW) and vertical flow constructed wetlands (VFCW) having dimensions: length; width; height of 60,30,20 cm and 30,30,50 cm respectively. The dilution ratio for leachate is taken as 1:2 (leachate: domestic wastewater). The flow rate of leachate is calculated as 5.41 lit/day and Hydraulic retention time for HSSFCW and VFCW is 2.52 days and 3.16 days respectively. The bed slope of 1% is given to constructed wetland for ease to flow. The filter media will consist of gravels of size 16 mm, 12.5 mm,4.75-10 mm and soil. The removal efficiencies of pH, Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Dissolved Oxygen (DO), nitrates (NO3), sulphates (SO4), chlorides (Cl), Total Dissolved Solids (TDS), Total Suspended Solids (TSS), oil and grease parameters are to be checked. Plants like Canna Indica, Phragmites Australis, Typha, Water Hyacinth, Cyperus Alterfolius, Duckweed, Chlorella Vulgaris, etc. are used for treating different types of waste water.In this laboratory scale study Eichhornia crassipes and Canna Indica are used in horizontal and vertical flow constructed wetland respectively.
