How On-Site Acid Neutralization Systems Provide Safe Chemical Disposal
When the right acid neutralization system is chosen, it can automatically add the required neutralizing chemicals to acid waste left over after a semiconductor manufacturing process step. Ideally such a system should use the least amount of chemicals while ensuring adequate neutralization of waste to comply with environmental standards. The system has to have enough […]
Choosing an Acid Neutralization System to Safely Handle Chemical Disposal
Wet process semiconductor manufacturing lines use aggressive chemicals to clean and etch silicon wafers. When a cleaning or etching step is complete, the remaining chemicals have to be disposed of safely. Low pH acids such as hydrochloric acid have to be neutralized with high pH chemicals so that the pH of the mixture approaches the […]
