Abstract
A purification device is provided that includes a porous container, purification media retained in the porous container, and a flow controller integral to the porous container. A purification device is also provided that includes a porous elastic container, purification media, and a flow controller. The porous elastic container has a pocket formed therein. The purification media is compressibly retained in the porous elastic container. The flow controller is elastically retained in the pocket of the porous elastic container.
Claims20
A purification device configured to be installed within a tank, the purification device comprising:
- a porous container having a porous end panel;
- purification media retained in the porous container;
- and
- a rigid disk disposed inside the porous container adjacent the porous end panel and configured to control a flow of fluid through the purification media, wherein the disk has a lower porosity than the porous end panel such that a fluid flow through the disk is restricted as compared to a fluid flow through the porous end panel.
A purification device configured to be installed within a tank, the purification device, comprising:
- a porous elastic container having a porous elastic end panel and a pocket formed inside the porous elastic container adjacent the porous elastic end panel;
- purification media compressibly retained in the porous elastic container;
- and
- a disk disposed inside the porous elastic container adjacent the porous elastic end panel and elastically retained in the pocket of the porous elastic container and configured to control a flow of fluid through the purification media, wherein the disk has a lower porosity than the porous elastic end panel such that a fluid flow through the disk is restricted as compared to a fluid flow through the porous elastic end panel.
A purification device comprising:
- a bag having a generally cylindrical side wall and a generally planar bottom wall, wherein the side wall and the bottom wall are both formed of an elastic fabric that is water permeable;
- a generally flat perforated disk having a bottom surface in contact with an interior surface of a bottom wall of the bag;
- and
- a granular filter material filling an interior of the bag, the filter material being in contact with the sidewall of the bag and an upper surface of the disk,
- wherein the elastic fabric of the bag is stretched by the granular filter material and the disk into a generally cylindrical configuration.
