Abstract: A well water treatment system includes a first ozonation tank that receives pressurized well water and introduces ozone into that well water. The ozone causes impurities to precipitate, which settle to the sides and bottom of the first tank. Remaining water is delivered by gravity flow to a second supply tank wherein the ozone is allowed to largely if not entirely dissipate from the water. When a household or other destination requires treated water, a pump in the supply tank operates to deliver water from the tank to that destination. The pump is operably positioned within the supply tank at an intermediate water level below precipitates floating on the surface and above precipitates that have settled in the tank.

Abstract: A system for the processing of materials includes a freezing section and a thawing section, with elongated channels extending through both sections, and gates between the sections and at the output of the thawing section. Large blocks of frozen material are slid from the freezing section to the thawing section; and a new batch of material is frozen with the heat from the freezing section used to thaw the blocks of frozen material. A harvest bar with dogs extending into the frozen material traverses at least a freezing section, and spray nozzles associated with the harvest bar may be used for cleaning the system.
