disposable filter cartridges, industrial, R3f, backwashable cartridge
In a world that is focussed at finding methods to use less energy or alternatives to existing energy driven products, one obvious change that is essential is the reduced use of disposable products. Specifically this paper will be addressing the reduced use of disposable filtration cartridges used in the water treatment industry…. A 12 plus billion dollar annual world market. “Throw away cartridges” is one of the major business units for the largest corporations in the water filtration market place. Reducing reliance on disposable filtration cartridges will have a significant economic impact on companies such as GE Water, Siemens, Pall Corporation and 3 M. This paper addresses the development of an alternative technology that allows filtration media to be reused over and over and as a result disposable filters are not required. It would be presumptuous to suggest that all disposable cartridge filters can be eliminated. For example in locations where there is no method to handle the cleaning waters used to restore the media (commonly referred as backwash water), disposable cartridge filters have an excellent application. Also for applications of low flow or sporadic flow requiring coarse filtration, the disposable cartridge filter serves a purpose in this market.
