Performance Removal Nitrate and Phosphate from Treated Municipal Wastewater Using Phragmites Australis and Typha Latifolia Aquatic Plants

It is known that ingredients such as nitrogen and phosphorus are the main nutrition elements for all living beings and plants; however the release of such ingredients into the water, which is the result of agricultural and industrial activity and can be found in urban sewage, is among the most menacing factor concerning the quality of water (Chang et al., 2009). Lagoon system can omit BOD, suspended solids, nitrogen, phosphorous also metals and other rare ingredients and pathogens. This system has a hyperactive biological activity, since there are different ilk if plants and species within the soil compound. This ilk can lead to the filtration of sewage and improvement of sewage quality (Kadlec and Brix, 1994). Aquatic shrub like Phragmites australis and Typha are used in countries like Egypt, Thailand and Japan under different conditions for purificationof sewage (Tang et al., 2009).
