    THE dissolved air flotation<\/strong> It is a piece of equipment widely used in the treatment of industrial effluents and oily water, being especially efficient in the removal of... oils, greases and solids in suspension<\/strong> present in contaminated water streams.<\/p>

    This technology, known internationally as DAF (Dissolved Air Flotation)<\/strong>It is applied in various industrial sectors, such as Oil and gas, petrochemicals, refineries, chemical industries, pulp and paper, mining, and industrial wastewater treatment.<\/strong>.<\/p>

    The operating principle of dissolved air flotation<\/strong> It is based on the generation of microbubbles of air or gas<\/strong> which adhere to contaminant particles present in the liquid. By binding to oil droplets or solid particles, these microbubbles reduce the relative density of the contaminants, promoting their absorption. ascent to the surface of the equipment<\/strong>, where they are removed by collection systems.<\/p>

    This process allows for efficient separation between oil, solids and treated water<\/strong>, ensuring high efficiency in the treatment of industrial effluents.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
