Abstract

— Many biological absorbents have been used from algae, bacteria, fungi and etc. for purification. Aquatic ferns have the ability to remove contaminants both live and non-polluting, which due to its rapid growth on the surface of the water in aquatic areas in any country, as an invasive species, threatens the aquatic life and ecosystem of the regions. Also, many pollutants have been removed and recovered using active sludge from municipal sewage treatment plants as dry and active powder (alive). In addition, ozonation is one of ecologically clean perspective methods for the treatment of industrial and household wastewaters. In this research a comparison of using the three mentioned for treating a combined domestic and industrial wastewater was accomplished and the results showed remarkable removals in Biological Oxygen Demand, Chemical Oxygen Demand and Total Organic Carbon, as well color and turbidity of the considered wastewater was tested after the treatment and magnificent reductions in both were seen. After achieving the final data in all con
