Abstract: This invention may involve a mobile parcel checking method, including training at least one individual on how to check parcels for hazardous contents and then offering parcel scanning services to at least one organization. A parcel scanner may be are dispatched to a site of the organization where the scanner checks parcels for at least one of chemical hazards, biohazards, and explosive hazards.

Abstract: An apparatus and method are provided to reduce the size of solid clumps of material and thereby permit reuse of the material. In particular, the apparatus and method allow for reuse of sediment accumulated in a storage area for paper pulping byproducts. The sediment is conveyed from the storage area to an tank. In the tank, the sediment is agitated to produce reduced-size clumps of the sediment. The reduced-size clumps are in a slurry that is capable of being burned at least one of a facility that produces paper pulp and a facility that produces paper products.

Abstract: The invention includes a method of minimizing the delivery cost of a slurry. According to the invention, a mobile tank is incompletely loaded with an at least partially dehydrated component of the slurry. Sufficient room is left in the tank for a diluent to be later added and the slurry constituted in the mobile tank. The incompletely loaded mobile tank is transported to a destination, thereby obviating expense associated with transporting a diluent portion of the slurry. At the destination, diluent is added to the tank and the slurry is constituted by activating a mechanical agitator within the tank. Slurry is then off-loaded from the mobile tank.

Abstract: The invention includes a transportable tank having an upper region and a lower region and a fluid conduit flow communicating the upper region to the lower region. The fluid conduit has at least one inlet opening in the upper region and at least one outlet opening in the lower region. A fluid conveyor associated with the fluid conduit repeatedly causes fluid to be circulated from the upper region, into the inlet, through the conduit, out of the outlet and back to the upper region.
