Title: John McCray: Innovator in Water Treatment Technologies

Introduction

John McCray is a notable inventor based in Golden, CO (US), recognized for his contributions to water treatment technologies. With 2 patents to his name, McCray has developed innovative solutions aimed at improving water quality through advanced remediation systems.

Latest Patents

One of McCray's latest patents is a biohydrochemical enhancement structure for stream-water treatment. This invention presents novel streamwater remediation systems and processes that involve the design and placement of geometric volumes of porous media with variable hydraulic conductivity within the streambed. These systems enhance hyporheic exchange, which is the exchange of water between the stream and the porous media. The disclosed systems aim to improve water quality by removing contaminants as water passes through the streambed. Contaminant removal is achieved through the use of microbes and reactive geomedia incorporated into the streambed structures. By pairing hydrologic structures with these elements, diverse contaminants such as metals, nutrients, organics, and pathogens can be effectively removed from the water. The structures are designed to return treated water to the stream, thereby enhancing overall stream water quality.

Another significant patent involves the extraction of pollutants from underground water. In this process, pollutants are extracted using an aqueous solution of cyclodextrin and a vertical circulating well. Complexes of the pollutant and cyclodextrin are recovered from the bottom of the well. For volatile pollutants, the complexes are separated into pollutant and cyclodextrin through air stripping.
