Introduction

Dennis M Flood is an accomplished inventor based in Oberlin, OH (US). He has made significant contributions to the field of water purification through his innovative patents. With a total of 3 patents, Flood has focused on developing advanced materials and methods for removing contaminants from water.

Latest Patents

One of his latest patents is a reusable composite filter material and methods for making and using the same for removing and destroying molecular contaminants from water. This invention utilizes a specially functionalized composite filter material with a high specific surface area to adsorb PFAs from potable water. The base filter material is granular activated carbon (GAC), which is sequentially coated with polydopamine, partially oxidized iron, and octadecylamine. After the PFAs are adsorbed, they are removed through a rinsing process, allowing the GAC particles to be recovered and recoated as needed. The PFA-containing effluent is treated using photochemical processes to destroy the PFA molecules, resulting in a non-hazardous material for disposal.

Another notable patent is a composite particle and method for removing contaminants from liquids. This invention describes a free-standing composite particle with a large surface area capable of adsorbing heavy metal contaminants from water. The particle consists of a granular activated carbon particle attached to one or more carbon nanotubes, covered by a thin film of polydopamine or similar polymeric material. The composite particles are mixed with contaminated water and processed through a hydrocyclone separator, allowing for the extraction of contaminants while purifying the water for reuse.
