Abstract: newline Wastewater discharged from a dairy farm contains a pH of 6.5 to 8.5 dissolved solids suspended solids sulphates phosphates nitrogen compounds oil and grease etc Since this wastewater contains inorganic salts casein detergents and sanitizers needed at the time of washing, it is responsible for increasing the organic matter content (BOD 1500 mg L-1 and COD 3000 mg L-1) in the wastewater This wastewater is released into the nearby water body or land before treating properly thus results in serious health and environmental issues Dairy influents can degrade very quickly and decrease the dissolved oxygen (DO) levels of the recipient water bodies The recipient water bodies may become a home for breeding of disease causing flies as well as other insects which is dangerous for human beings Increased concentration of dairy wastes in the receiving water bodies is also harmful for the survival of aquatic life Dairy influent depletes the DO levels increases anaerobic conditions causes taste and odour problems imparts colour and turbidity and also promotes eutrophication Thus discharge of dairy wastewater into streams lakes and rivers disturb the ecological balance by polluting water air and biodiversity Hence it is very essential for a prompt and adequate treatment before disposing into the environment newlineFor treating such medium to high strength pollutant containing wastewater Constructed Wetlands (CWs) have proved to be very efficient alternative CWs are man-made engineered water purifying systems which act as natural wetland filters in several ways such as treatment mechanisms vegetation filter substrates and microbial communities CWs consists of impermeable clay synthetic liners and engineered configurations for maintaining fluid flow fluid retention time and water level Primary components responsible for constructing a CW includes fluid filter media microorganisms and surface vegetation These systems basically depend on aerobic and anaerobic microbial activities and the fluid flows through filter substrates
