Concrete grindings reclamation system

A method for recovering water from a concrete grindings fluid slurry containing water, cement particles, and sand, the method comprising

• collecting the concrete grindings slurry from a concrete grinding apparatus that includes water feed apparatus and feeding said slurry to vibratory separation apparatus,
• treating the fluid slurry with the vibratory separation apparatus, the vibratory separation apparatus having screen apparatus for materials, the vibratory separation apparatus producing wet solids including said sand flowing off the top of the screen apparatus and a fluid stream containing water and cement particles, the fluid stream discharged beneath the screen apparatus,
• feeding at least a portion of the fluid stream to centrifuge apparatus,
• separating cement particles from the fluid stream with the centrifuge apparatus and producing a stream of water with the centrifuge apparatus, and returning said stream of water for re-use in the concrete grinding apparatus,
• filtering at least a portion of the stream of water with filter apparatus to filter out undesirable material from the stream of water,
• wherein at least a portion of the stream of water from the centrifuge apparatus is fed back into a truck tank of a truck for return to a site at which the fluid slurry is produced,
• wherein the grinding apparatus is remote from the vibratory separation apparatus and remote from the centrifuge apparatus, or
• wherein the vibratory separation apparatus and the centrifuge apparatus are located adjacent the grinding apparatus, and
• wherein at least 90% of the stream of water produced by the centrifuge apparatus is recovered for re-use in the concrete grindings apparatus.
