08-03: Recycled Water for Cooling 4000oF Melted Sand

Using recycled water for cooling molds and vacuum pumps in a Kentucky glass factory was tried and failed. So, municipal water was used once again as a cool heat sink at a hot price -- ,000 a month hot. After investigating new recycle options, a new water treatment system was installed in the fall of 2006 resulting in a full payback in just 33 days. Nearly 10% of the world's incandescent light bulbs are blow in this facility utilizing 1-2.5 MGD of recycled water contributing to the conservation of valuable potable water. This manuscript tells how this was done along with the benefits and hazards.
