Non-Potable Water For The Concrete Industry
Aug 03, 2016
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:
- A rotating drum is pre-coated with a filter media called diatomaceous earth (DE).
- 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.
- 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.
- 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.
