Abstract: Animal litter comprising composite particles including powdered sodium bentonite and powdered activated carbon, agglomerated together into the composite particles, wherein the animal litter has a particle size distribution of 16/50 mesh (i.e., 300 ?m to 1180 ?m in size). The litter may include non-composite, granular clay particles (e.g., granular sodium bentonite) having the same particle size distribution (16/50 mesh). Such particle size characteristics significantly reduce dusting, without the need for a de-dusting agent, reduce clump depth and/or reduce clump width at the bottom of the clump (both acting to reduce risk of clumps sticking to the bottom of the litter box) and result in more efficient use of the litter in clumping (reduced clump weight) by increasing absorbency.

Abstract: A system and method of distilling/desalinating water in a vacuum-applied multi-phase manner purifies water of its dissolved and/or undissolved contaminants. The system includes at least one primary vessel, at least one vacuum apparatus, and at least one secondary vessel. The primary vessel initially retains a quantity of source water. A vacuum pressure is then generated inside the primary vessel with the vacuum apparatus, which evaporates a first water portion off the source water and freezes a second water portion on the source water. The first water portion is then condensed inside the secondary vessel. After the remaining source water is drained out of the primary vessel, the first water portion in its liquid state is transferred into the primary vessel and poured onto the second water portion in its solid state, which melts the first water portion and the second water portion together to be a quantity of purified water.
