Abstract
Official abstract text for this publication.
A fluid treatment apparatus comprising a tank containing a bed of at least one fluid treatment medium, a distributor plate separating the bed from an end portion of the tank, and an inert medium comprising amorphous particles having a harmonic mean diameter from 2.5 to 250 mm and a density from 0.57 to 0.998 cm3/g. The volume of the end portion containing inert medium is from 25 to 95% of the total volume of the end portion.
First claim
Opening claim text (preview).
The invention claimed is: 1. A fluid treatment apparatus comprising: (a) a tank comprising a bed of at least one fluid treatment medium, (b) a distributor plate separating the bed from an end portion of the tank, and (c) at least one inert medium comprising amorphous particles having a harmonic mean diameter from 2.5 to 250 mm and a density from 0.57 to 0.998 cm 3 /g; wherein the end portion has a total volume; and the volume of the end portion containing inert medium is from 25 to 95% of the total volume of the end portion; and wherein the amorphous particles have an average sphericity from 0.7 to 1 and an average roundness from 0.4 to 1. 2. The fluid treatment apparatus of claim 1 in which volume of the end portion containing inert medium is from 30 to 90% of the total volume of the end portion. 3. The fluid treatment apparatus of claim 2 in which the harmonic mean diameter is from 2.5 to 100 mm. 4. The fluid treatment apparatus of claim 3 in which the amorphous particles have an average sphericity from 0.7 to 0.95 and an average roundness from 0.45 to 0.95. 5. The fluid treatment apparatus of claim 4 in which the fluid treatment medium is an ion exchange resin. 6. The fluid treatment apparatus of claim 5 in which volume of a lower end portion containing inert medium is from 40 to 90% of the total volume of the lower end portion.
