Water treatment using ferrate-based redox process and filtration
The granted patent US11999644B2 outlines a comprehensive process for treating contaminated water streams using a series of continuous steps. The process begins with the introduction of ferrate into a redox reactor, which transforms the contaminated water into redox water. This water is then clarified to remove particulate contaminants, resulting in clarified water. A two-stage filtration system further processes this clarified water to yield treated water. The method includes specific feeding protocols for ferric compounds and acidic oxidants at various stages, ensuring optimal chemical reactions occur in situ within the redox reactor. Additionally, the process incorporates a buffer tank for raw source water and allows for the continuous removal of contaminated water.
Further enhancements to the treatment process are detailed, including the use of flocculant-adsorbent solutions to improve contaminant removal efficiency. The patent specifies volume ratios for the ferric compound and acidic oxidant solutions, as well as the flocculant-adsorbent solutions, to maintain effective treatment conditions. The process also includes mechanisms for sludge management and backwash water handling, ensuring a comprehensive approach to water treatment. Importantly, the method allows for the analysis of contaminant concentrations before and after treatment, demonstrating the effectiveness of the process in reducing contaminants in the treated water. Overall, this patent presents a systematic and efficient method for water purification that could have significant implications for environmental management and public health.
