Microbiological Purification of Wastewater Using Butomus

Water samples were collected three times a week to make chemical, physical and microbiological tests, in order to determine the role of Macrophytes in improving and enhancing domestic wastewater purification processes, by the means of providing the necessary oxygen for microorganisms; absorbing some metal elements and chemical ions in addition to adsorbing a portion of microorganisms on its surfaces. This will lead to the completion of water purification and mineralization processes. Necessary tests for evaluating the purification processes had been carried on raw and treated water for a period of 17 days each experiment, using special tanks previously made for this purpose. The results obtained confirmed the effective role of microorganisms in domestic wastewater treatment and water purification using macrophytes which were capable of providing the suitable conditions to motivate heterotrophic microorganisms, which are characterized by the ability to decompose the organic matter and its active oxidation, which affects the concentrations of nitrates, ammonium, suspended solids and electrical conductivity... Etc. Tests results clearly confirm the positive effect of Macrophytes as Butomus umbellatus on enhancing purification processes and activating the organic matter mineralization by microorganisms.
