Latest Patents
One of her latest patents is titled "Biological water treatment by alternating continuous and sequential aeration." This method focuses on biologically treating water, particularly through a process that involves nitrifying and denitrifying water. The process employs both continuous and sequential aeration modes. In the continuous aeration mode, nitrification and denitrification reactions occur simultaneously when the nitrate concentration of the water reaches a predetermined low threshold. Conversely, the sequential aeration mode is activated when the nitrate concentration reaches a predetermined high threshold. During this mode, aeration is ceased when the ammoniac concentration reaches a predetermined low threshold and is activated again when the ammoniac concentration reaches a predetermined high threshold.
