Introduction

David S. Ross is an accomplished inventor based in Lorain, OH (US). He holds a total of 6 patents that showcase his contributions to the field of filtration technology. His innovative approaches have led to significant advancements in the operation of granular medium filters.

Latest Patents

One of his notable patents is for an "Underdrain for Granular Medium Filter." This invention presents an improved apparatus and method for operating a granular medium filter. The apparatus features an enhanced underdrain structure composed of multiple rectangular compartments, allowing the filter bed to be 'air pulsed' and backwashed for thorough cleaning. The nozzles positioned within these compartments direct fluid vertically into the filter bed, aiding in the breakdown of the bed during backwashing and counteracting size classification of the medium.

Another significant patent is titled "Pulsing Portions of a Filter Cell to Extend a Filter Run." This method improves the operation of a down-flow granular medium filter by increasing the effective filtration time between backwashes. The filter tank cell is divided into several subcells, each controlled for periodic upwardly-directed pulses of fluid through the filter bed. This innovative approach enhances the porosity of the filter bed while maintaining filtration in the remaining subcells.
