Assessment of Hazardous Chemical Pollutants Removal in Industrial Wastewater Treatment by Comparing Ozonation, Active Sludge and Aquatic Ferns Usage

One of the most dangerous sources for water pollution is chemical fertilizers such as phosphor and nitrogen contents as well as petroleum contaminations via aromatics, heavy metals, grease, phenols and etc. These aforementioned compounds and some other chemical contaminants should be removed before uploading the wastes to the environment regarding to their dangerous and poisoning navigates. The aim of this research is providing suitable data for industrial application of economic useful absorbent for chemical and physical treatments. So, three different methods of ozonation, aquatic ferns usage and active sludge was considered, experimented and compared in order to remove the hazardous chemical contaminants, specifically NO2 - , NO3 - , PO4 3- , NH4 + and C6H5OH. All the three methods showed acceptable removals, but it should be mentioned that aquatic ferns illustrated great power as an environmental friendly absorbent in the contaminants removal.
