Non-Potable Water For The Concrete Industry

From the National Ready Mixed Concrete Association: The CA Division of State Architect has drafted a regulation to provide instructions on the use of non-potable water sources for use as mixing water in concrete. It permits the use of non-potable water that has been qualified within guidelines of ASTM C1602.

The Alar Auto-Vac C-Series Filter has redefined wastewater filtration in the concrete industry. The filter uses vacuum technology through the following steps:

  1. A rotating drum is pre-coated with a filter media called diatomaceous earth (DE).
  2. After the pre-coat is complete, cement fines are pumped into the pan where the drum is rotating, the vacuum pulls the clean water through the drum and traps solids larger than 1/2 micron on the DE surface.
  3. After the surface of the drum is blinded, a variable speed blade advances and removes the solids from the drum surface leaving a clean layer of filter media.
  4. The clean water is pumped to a non-potable water tank for reuse.

Concrete Operations Include but Not Limited To:

Ready Mixed - Precast - Color/Iron Oxide Pigments - Sawing/Grinding/Grooving/Polishing/Drilling - Roofing & Concrete Tile

The Auto-Vac comes in 16 sizes to accommodate virtually any volume.
