Latest Patents
One of Andrew J Nelson's notable inventions is a self-regenerating biofilter. This biofilter is designed to receive untreated water through an intake inlet, filter it through a filtration mass, and expel purified water through an output outlet. The filtration mass consists of gravel and activated carbon layers separated by a mesh screen. A compressed air line is located below the mesh screen, allowing for periodic self-cleaning. The biofilter self-cleans by opening a flush valve that expels a flush water stream carrying debris. Additionally, it self-regenerates by stopping filtration for a time, allowing biological matter left on the activated carbon to degrade into biomass. Periodically, the biofilter removes and flushes out biomass by applying water or a combination of air and water. This innovative design has garnered attention for its efficiency and effectiveness in water treatment.
