A filter media is positioned within the chamber.

An apparatus and methods for sanitizing and cleaning filtration systems is provided. The apparatus includes a chamber fluidly connected to a source of fluid for backwashing the system, and a heat exchanger for increasing the temperature of the fluid. A filter media is positioned within the chamber. The method of sanitization involves backwashing the apparatus to remove debris, then continuing to circulate the backwash fluid through the system while increasing the temperature of the fluid, until the temperature of the water and apparatus is sufficient to deactivate microorganisms. The method may also involve increasing the disinfecting power of the fluid by adjusting the pH of the fluid. The apparatus may be provided with a scavenger to assist in the substantially complete removal of fluid from the chamber during and after a steaming or cleaning process. The method may also involve reducing the pH of the feed water during normal operation to convert monochloramines to dichloramine and trichloramine in order to aid in the removal of chloramines from the feed water.
