Know Your Resin
The performance of a water softener or any water treatment device utilizing ion exchange resins can be assessed by measuring exchange capacity, moisture content, iron fouling, and physical composition. Specific elements can also be tested for upon request. Testing your resin is the best way to determine whether it is time to replace your resin or get a new water softener.
The certified water specialists at TG Analytical Laboratories can not only test for these qualities, but are qualified to assess the quality of your resin.
SAC

Strong Acid Cation Resin is typically used for removing hardness. These types of resins can also be used to remove other cations like iron.
SBA

Strong Base Anion Resins are typically used to exchange anions like nitrate, sulfate, chloride, nitrite, fluoride, and bicarbonate.
Mixed Bed

Mixed Bed Resin is a combination of cation and anion resin. The resins produce deionized water or remove specific combinations of contaminants.
