10.06.2020Let us look at what causes this problem. Let us assume that in atypical case, a low set point of 6 pH has been set. It would mean that when the pH drops to a value below 6, the caustic dosing pump starts. The addition of caustic solution would start to increase the pH. When the pH reaches 6, the pump would stop.

Drilling fluid additives were developed to be mixed with water with a pH level from 8.5 to 10 in order for the required chemical reaction to occur and to provide a proper yield. Most water sources range from 5.5 to 7.5 which is too low. The easiest way to check pH level is to use a simple pH testing strip, similar to ones sold to check swimming
