Latest Patents

Among her latest innovations are two remarkable patents focused on treating contaminated water. The first patent deals with a method for the treatment of contaminated water utilizing metal oxide media, which includes a combination of iron oxides and hydroxides. This material, derived from the basic-oxygen steel-making process, enhances phosphorus adsorption and promotes calcium precipitation through increased pH levels. By adding limestone to the oxides, the system ensures a long-term source of calcium, vital for maintaining high pH levels over extended periods.

The second patent presents a comprehensive system for treating contaminated groundwater, especially when dealing with acidity and other harmful contaminants. This innovative system involves excavating a trench in the aquifer along the contaminant plume's path and placing an active material that reacts chemically with the contaminants. Depending on the specific contaminant, various materials such as organic carbon, pyrite, or elemental iron are employed to facilitate safe chemical reactions, ultimately converting harmful contaminants into harmless precipitates.
