Innovative treatment solutions for oil polluted water

Oil polluted water is not rare on the Earth and treating it in energy efficiency way to be properly returned to the environment is of great interest. This work makes an analysis of several technologies and selects some of them to be included into a complex treatment system starting from polluted water found in various places on Earth to the level of being released in nature, or event to use the treated water in human activities. Several stages of treatment are set: solid separation, oil separation, remained water treatment, filtration and evacuation. Separation of solids is made with less used and more energy efficiency technology. Also, oil from water separation is made with a new and very efficient technology, permitting future recovery of the separated oil for energy or semi-green hydrogen production. After releasing solids and removable oil, the polluted water is treated in more efficient way with natural components and with no polluting output based on ozone, oxygen and nitrogen gases in nano-bubbles form. All gases are extracted from natural air and converted in strong reactors through equipment presented in the work. The nanobubbles treated water releases the reaction by-products as oxides of metals to be filtered and oxygen, hydrogen, nitrogen, CO2 gases to be released into the atmosphere before being clean to be released to the emissary.
