Abstract
A unitary, one-piece salt grid, not subject to disassembly during shipment or installation in a brine tank, which is nestable into other grids for convenient shipment or storage prior to placement into the brine tank. The unitary salt grid includes a generally planar platform suitable for supporting and elevating granular salt above at least a portion of a concentrate brine in the bottom of the brine tank by spanning the interior area of the brine tank at a spaced position above the bottom of the tank, reinforcing ribs forming an integral part of a lower side of the platform to maintain the shape of the platform under the weight of the salt on an upper surface of the platform, and a plurality of supporting feet also forming an integral part of the platform and adapted to engage the bottom of the brine tank and support the platform at the spaced position above the brine tank bottom. The supporting feet include hollow frusto-conical sections such that the salt grids are nestable into one another.
