Absorbent particles suitable for use as an animal litter according to another embodiment include first absorbent particles having a first general shape and second absorbent particles having a second general shape, where the second general shape is different than the first general shape. Agitation of the absorbent particles may cause the first and second absorbent particles to segregate. Agitation of the absorbent particles may cause the first and second absorbent particles to orient with each other in a targeted way.

The first grain size can be between about 50 and 100 ?m and the second grain size can be between about 100 and 150 ?m. In other arrangements, the first grain size can be between about 70 and 90 ?m and the second grain size can be between about 100 and 130 ?m. The difference between the first grain size and the second grain size can be at least 20 ?m. In other arrangements, the difference between the first grain size and the second grain size can be at least 10 ?m.

Abstract: A filtering device for a gravity-flow liquid treatment system includes a first filter component that can be either exposed or adjacent to a substantially transparent region in at least a portion of a filter housing. The first filter component is capable of providing a visual indication of exposure to at least one contaminant. The contaminants for which the first filter component can indicate exposure include particles, inorganic, and organic contamination. Particle contamination is indicated by a change in color of the first filter component through particle collection. Inorganic and organic contaminants are indicated by reaction with at least one agent capable of undergoing a color-change reaction in response to at least one contaminant.

Abstract: A combination tool for cleaning and sanitizing a surface is disclosed. The tool includes a cleaning device and at least one UV flash unit.

Abstract: A porous composite block is provided that contains at least two groups of binding agent particles. The first binding agent particles have an average particle size between about 5 ?m and 200 ?m. The second binding agent particles have an average particle size no larger than half the average particle size of the first binding agent particles and also between about 10 nm and 30 ?m. The porous composite block can also contain active grains and active granules such that the granules are smaller than the grains. The grains and the granules can be capable of treating water. A method of forming a porous composite block and a water treatment system are also provided.

Abstract: A system for enhancing water is described. The system includes a housing with an inlet and an outlet, source water at the inlet, which can flow through a filter component in the housing and thus become treated water, and at least one enhancement module that can dispense an enhancement into the treated water as it flows through the outlet.
