Ozone-Flotation Innovative technique for preliminary sedimentation based on ozone, destined to the treatment of changing organical loads in effluents. Functionality - oxytec's ozone-flotation systems decrease the total amount of germs populating the wastewater, reducing all water-soluble colours and transforming stable organic compounds (e.g. toxines) into less nocuous or nontoxic final products. In addition, flotation systems contribute to the reduction of the water's CSB-, BSB5- and grease concentration. - This system operates without the need of additional chemical agents or pressure tanks. - As final product a pure sludge is obtained, free of chemical remnants. - On/Off system Advantages - low space requirements - low power consumption - easy manteinance - reduced effluent disposal - resistand against significant load variations (over- and underloading) - no appliance of chemical agents - no toxic remnants - reusability of the water for processing, cooling or washing purpouses - worldwide tested operational reliability
