Determination of the Drag-Out
SurTec Technical Letter 11

The consumption of chemicals in processes of surface treatment is mainly caused by the drag-out of bath solution. Knowing the amount of the drag-out helps to maintain the process stable and is necessary for minimizing waste water and dosage of additives. Mostly, the values of the drag-out only are estimated - sometimes they are unknown. However, it is very easy to find out how much bath solution is dragged out. This Technical Letter shows how to determine the drag-out using two examples taken from the electroplating technique.
