Title:
METHOD AND APPARATUS FOR A WATER FILTER BACKFLUSH
Document Type and Number:
WIPO Patent Application WO2005003469
Kind Code:
A3
Abstract:
A method and corresponding apparatus employ purified water to back flush a filtration device (101). Purified water includes water having a total dissolved solids reading less than that of the water being filtered. Examples of purified water may include water treated using reverse osmosis, steam distillation, or deionization processes, and the like. In the simplest form, the purified water is used to rinse or back flush the filtration device (101) Further extensions include valves (102, 103, 104) to switch from a primary flowpath used for normal operations to a secondary flowpath used to conduct backflushing routines. Back flushing routines may be initiated on demand or through an automated routine that repeats the process on a regular basis.
