摘要：The primary treated effluent was treated using constructed wetlands which is highly effective and ecofriendly, it uses plants, microbes and gravity to transform wastewater into gardens and reuse water. They use rootedwetland plants (vetiver) and bio-filter to improve the water quality. Bio-filter was developed using organic andinorganic media. Inorganic media include sand and gravel. Organic media includes wood charcoal. Vetiver grass is aversatile hardy plant, deep, fast growing and fibrous root systems and shows good treatment efficiency forcontaminants present in the effluent. The different properties of the filter aggregates was analysed and inferred withEnvironmental Protection Agency (EPA) water treatment manuals filtration. The filter aggregates have macro porosityand allow better regulation of water flow. The main aim of this study was to find out the properties of filter media andthe effectiveness of vetiver grass (Vetiveria zizanioides L.Nash) in the treatment of wastewaters in constructedwetlands.
