Sulfate removal using Ion Exchange Resin

Abstract Sulfate contamination can cause corrosion, which can affect operation and downtime for maintenance. Dynalene’s ion exchange resin can be used to reduce the sulfate concentration to below 1mg/L.   Introduction Sulfate in fluids used in the industrial application can be corrosive. They can cause scale buildup in the pipes leading to clogging. The Environmental

Selenium Removal using Ion Exchange Resin

Abstract Low concentrations of selenium (Se) in elemental form is relatively safe for drinking water and aquatic life, however elemental selenium and its compounds are toxic in high dosages [1]. The removal of selenium was investigated using two different ion exchange resins. Dynalene’s ion exchange resin was able to reduce the selenium to below 4.5

Lead Removal using Activated Carbon

Abstract Lead contamination is most commonly found in drinking water [1]. Activated carbon was used to reduce the concentration of lead in an aqueous solution to less than 7.8 µg/L. Introduction Lead contamination in drinking water is mostly found through corrosion of pipes connection homes to the water main. The maximum contamination limit (MCL) set
