Latest Patents
One of his latest patents is the "Self-cleaning siphon-actuated radial flow filter basket." This apparatus treats stormwater and features a cylindrical basket with a housing that includes a circumferentially extending air slot near the base. The basket contains an annular bed of absorbent material surrounded by a filter cartridge. Water flows radially inward through the filter and the bed into a cylindrical inner drainage space, which has an outlet at its lower end covered by a float valve. During operation, the float valve lifts when the water level rises, allowing air to be expelled from the drainage space through a one-way valve. This process ensures that water is continuously siphoned through the basket apparatus. When the water level drops, air enters through the air inlet slot, scouring the filter and dislodging particulates, thereby maintaining the infiltration capacity of the basket filter.
Another notable patent is the "Apparatus and method for treating storm water runoff." This invention is designed to remove contaminants that accumulate in stormwater as it flows over paved surfaces in urban areas. The apparatus includes a basket with an outer surrounding water-permeable wall and an inner water-permeable wall. A bed of absorbent material is placed between the walls, allowing fluid communication. During operation, stormwater flows through the outer wall into the bed, where it is treated, and then flows through the inner wall into an inner drainage space. Treated water is then directed into a drainage conduit for disposal. The absorbent material can include various substances such as compost, activated carbon, and clays, and the baskets are designed for modular construction to facilitate easy maintenance.
