What it does?
One-Way Vapor (OWV) ensures that the used acid is discharged directly from the system and does not return to the acid reservoir to cause secondary contamination.
What is the benefit?
In traditional techniques, the waste acid will return to the acid reservoir to evaporate and be used again. The waste acid continuously contaminates the pure acid. The resulting vapor becomes dirtier and the cleaning efficiency is reduced, as a result only ppb-level cleaning can be achieved even using trace metal grade pure acid.
