A method of and apparatus for extending the life of fountain solutions used in commercial printing presses comprises withdrawing fountain solution from the dampener recirculation system of a printing press and directing the withdrawn fountain solution through a sediment prefilter, a separation filter, and a post treatment filter. The sediment prefilter preferably comprises a melt blown polypropylene filter; the separation filter preferably comprises a diatomaceous earth filter; and the post treatment filter preferably comprises a zeolite filter.

Fountain solution recycling system for commercial printers

A water treatment system includes a cylindrical water filter having a cylindrical exit passageway. A plurality of spheres are formed from a predetermined water treatment chemical agent. The spheres are positioned at spaced apart locations along substantially the entire length of the exit passageway of the cylindrical water filter.
