Highly porous coolant conditioning and remediation media

Abstract

The present invention is a solid cooling fluid treatment medium, usually but not always in bead form, suitable to be brought into contact with coolants to remediate and to condition them. A key feature of the medium, typically a polymeric resin, is the presence of relatively very large pores, which are able to capture and remove ultrafine coolant contaminants and breakdown products (such as colloids, soot, coke, organics, scale or other small semi-soluble or insoluble particles). Resins and adsorbents of the prior art have proven unable to remove ultrafine contaminants like these that have a deleterious impact on industrial equipment performance and reliability. The mean pore size diameter of the medium is between about 1,500 Å and 100,000 Å and, more preferably, in the range of about 1,500 Å to about 80,000 Å.
