Abstract: An apparatus for inhibiting the growth of microbiological organisms in commercial icemakers and coolers by treatment of the air within the device evaporator air space. The apparatus includes a mechanical filtration device, a PCO device, and a UV light device. Air is drawn from the evaporator space, mixed with a small amount of ambient air from around the apparatus, and mechanically filtered to remove particulates. The filtered air is then passed through the PCO device that is activated by the UV light device, where it is treated by the ROS produced by the activated PCO device. A UV light further produces ROS to treat the filtered air stream, which is returned to the internal space of the commercial refrigeration device. Recirculation of the treated air increases residence time. The addition of a small amount of external air with the internal air allows for positive pressurization of the evaporator space.

Abstract: 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comprises withdrawing fountain solution from the dampener recirculation system of a printing press and directing the withdrawn fountain solution through a sediment prefilter, a separation filter, and a post treatment filter.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.

Abstract: 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.

Abstract: The present invention relates to a system and method for notifying customers. The system is designed to receive information from the customer related to a filter or a filtration system and equipment served by the filtration system, use that information to compute a replacement time for the filter; and contact the customer in one or more different ways at an appropriate time. Some of these forms of contact include sending reminder messages and automatically sending replacement parts or dispatching a service entity to change the filters at an appropriate time.
