Gasim Hayder Ahmed Salih, Syaza Nadia Binti Adnan, Puniyarasen Perumulselum


Bio-filtration is a pollution control method to capture and degrade the wastes using the living material. Basic uses incorporate handling waste water, capturing destructive chemicals or sediment from surface runoff, and microbiotic oxidation of contaminants in the air. In this research, three different plants will be used to identify the most effective plant for the removal of nitrate and phosphorus in wastewater treatment system. Three different plants were used as bio-filter. They are Phragmites (paddy), Ipomoea Aquatica (water spinach) and Pistia (water lettuce). From these results, it can be concluded that, from the three plants, water lettuce is the most suitable plants for bio-filtration for removal of nitrate and phosphorus. This is because, from the entire test, water lettuce showed the highest percentage removal compared with the other two plants. It removed up to 61 % of TSS, 89 % of COD, 57 % of nitrate and 37 % of phosphorus.
