Latest Patents

Marshall holds a patent for a "Method for regeneration of a water softener." This demand-initiated method operates the softener ion exchange bed over a capacity range in which the resin is most efficiently restored by exposure to brine. The system adjusts the reserve capacity of the softener based on the amount of softening capacity used since the last regeneration. Additionally, it determines the quantity of saturated brine to be used for the next regeneration, which is scheduled when the reserve capacity is exceeded or when the remaining available capacity will not be adequate for normal usage on the next day of the week. This innovative method enhances the efficiency and effectiveness of water softening systems.
