Freescale Semiconductor and Nalco Team up to Save Water

Apr 9, 2014

Freescale Semiconductor is a major semiconductor producer manufacturing MEMS, microcontrollers, radio frequency transceivers and amplifiers. One of manufacturing fabs is in Austin, Texas. The fab has a cooling tower in a central utility system, supporting the chillers that supply Process Cooling Water (PCW) to the fab.

Like most semiconductor manufacturers, Freescale has a strong environmental and local community commitment. The utility staff needed to be able to continue to support the manufacturing processes, but also wanted to reduce the amount of water the fab was consuming and discharging.

Freescale and Nalco put into place a process that included complete overhaul of automation systems, technical approach and goal-based planning. This included the earlier described improved chemical delivery method, 3D TRASAR Technology for Cooling Water, results documentation, and summarizing progress and setting new goals.
