Soda ash | SLB
Soda ash is the common name for sodium carbonate (Na 2 CO 3 ). It is a weak base that is soluble in water and dissociates into sodium (Na) and carbonate (CO 3) ions in solution. Calcium is present in many makeup waters and formations. It can cause flocculation of the mud, resulting in increased rheology, gel strengths, and fluid loss.

pH – Acidity of Private Drinking Water Wells
When acidic water is treated with a neutralizing filter such as ground limestone (calcium carbonate), hardness is added to the water. This happens as a result of adding calcium and magnesium minerals that the water absorbs when passing through the filter. This is also why the neutralizing materials need periodic replenishment.
