TREATMENT OF TEXTILE WASTEWATER USING VERTICAL FLOW CONSTRUCTED WETLAND WITH PLANTED ALTERNANTHERA SESSILIS AND ZEA MAYS

Constructed wetland is a promising approach to remediate the industrial effluent. The detoxification of industrial effluent in a constructed wetland system may be enhanced by macrophytes with beneficial bacteria that are able to degrade contaminants present in textile effluent. Vertical Flow Constructed wetland (VFCW) systems have been used as a cost effective alternative to conventional methods of wastewater treatment. The system has engineered and monitored was set-up with limited resources in terms of manpower and materials, and also easy to maintain and to manage. It is observed that these adsorbents are active in removal of dye and harmful pathogenic bacteria. From this study, the promising attributes of Alternanthera sessilis and Zea mays includes its tolerance to dye and dye absorption along with good root development, low maintenance and ready availability in contaminated regions. The significant decrease in color, turbidity, temperature, pH, Electrical Conductivity (EC), Total Solid (TS), Total Suspended Solids (TSS), Total Dissolved Solids (TDS), Total Alkalinity, Chloride, Hardness, Chemical Oxygen Demand (COD) and Biological Oxygen Demand (BOD) are taken as indicators of effectiveness of phytoremediation.
