Abstract: A fluid distributor comprises a distributor body having a fluid port at one face and a distribution surface at the opposite face, with the distribution surface having a plurality of uniformly spaced distribution openings. Fluid passages defined by channels and bores in the distributor body provide fluid communication between the fluid port and the distribution openings such that there is substantially equal fluid flow to each distribution opening. A method of fluid distribution particularly adapted for chromatography applications is also disclosed.

Abstract: A carboxylated latex is added to an aqueous slurry of fibers to remove metal ions contained in solution. The water is removed to form a felt. The demetallized water removed during felt formation is recycled in a closed process water system. The carboxylated latex is formed by polymerizing an unsaturated carboxylic acid on a substantially surfactant free styrene-diene polymer latex.
