Sulfate challenges vary significantly. For example, one of the most important considerations in deciding how to manage a sulfate-laden wastewater flow is the total dissolved solids (TDS). Once our team completes a chemistry review, most of our clients' sulfate removal needs can be addressed with one of a high- or low-TDS approach.

The minerals that cause the hardness stick to the resin, and the sodium dissolves in the water. Ion exchange systems for removal of sulfate use a different type of resin, but they work in an analogous manner. Sulfate ions in the water switch places with other ions which are on the resin, usually chloride. When the resin is full with sulfate, it ...
