Removal of 0.1 suspended water in JP-5 fuel was measured in a separometer using a variety of glass, synthetic, and metallic fiber mats. Addition of 25 ppm a corrosion inhibitor lowered the WSIM from 99 to 77 or - 4, and had more or less adverse effect on all materials examined. It was discovered that this adversity could be overcome by using a 2-layer combination of fiberglass upstream and fibermetal downstream. The glass alone gave an index of 40 the metal had no coalescing action at all index 20 the combination gave an index of 100. The pressure drop across the combination was low. A downstream layer of sintered polyethylene fiber had a similar but less pronounced synergistic effect. In clear JP-5, addition of 10 of marine diesel fuel lowered the WSIM to 84 0.1 antiicer apparently had little or no effect. For glass mats, the variation in index and pressure drop with fiber diameter, packing density, cell depth, and fuel flow rate and water content was observed.
