Abstract

A system and method for purifying a fluid and a method for regenerating a permeable purification medium comprise contacting a purification medium with a warm cleaning liquid for a period of time.

Claims

1. A method for regenerating a permeable purification medium comprising:

contacting the purification medium with a warm cleaning liquid for a period of time and removing foulant materials from the purification medium.

2. A method for purifying a fluid comprising:

directing a flow of fluid to a purification medium including passing permeate through the purification medium;

interrupting the flow of fluid;

contacting the purification medium with a warm cleaning liquid for a period of time;

removing foulant material from the purification medium; and

reestablishing the flow of fluid to the purification medium.

3. A system for purifying a fluid comprising:

a permeable purification medium having a first side and a second side, the first side communicating with the fluid and

a source of warm cleaning liquid coupled to the purification medium to establish contact between the warm cleaning liquid and the purification medium for a period of time.
