Title: Innovations by Peter S. Cartwright in Water Softening Technology

Introduction

Peter S. Cartwright is an accomplished inventor based in Bloomington, MN (US). He holds a total of 4 patents that focus on advancements in water softening technology. His innovative approaches have significantly contributed to the efficiency and sustainability of water treatment systems.

Latest Patents

One of his latest patents is titled "Water softener using nanofiltration to reclaim a portion of the regenerating solution." This invention includes a water softening system that recycles a substantial percentage of the solution used for regenerating the system. The system consists of a brine tank and a softening tank through which hard water passes during normal operation. During the regeneration mode, the solution of sodium or potassium ions in the brine tank passes through the softening tank, acquiring hardness ions. It then flows through a nanofilter that allows a higher proportion of sodium or potassium ions to pass from a high-pressure side to a low-pressure side. The hardness ions are directed to a drain, while the liquid passing through the nanofilter contains salt that returns to the brine tank for reuse.

Another notable patent is "Water softener system using nanofiltration to reclaim a portion of the regenerating sodium chloride." This system also recycles a significant percentage of the brine. During the regeneration cycle, the brine solution in the brine tank passes through the softening tank, acquiring hardness ions, and then through a nanofilter. The nanofilter allows a higher proportion of brine ions to pass than hardness ions, with the hardness ions flowing to a drain. The liquid passing through the nanofilter contains salt that is returned to the brine tank for reuse. A preferred embodiment of this invention includes a pump to force the brine solution through the nanofilter.
