Chisholm Creek Water Treatment Plant (Chisholm Creek) in Oklahoma City, Oklahoma needed an odor solution for their extremely elevated levels of H2 S and other sulfur compounds released during sewage processing. The city was interested in an effective, low-cost solution for complete odor removal. Wanting to stay away from high maintenance units, like chemical or wet scrubbers, PureAir recommended using a Dual Train VBS-720 system and Sulphasorb FeXL™ and Sulphasorb XL™ adsorbent media. The VBS-720 is a limited maintenance system designed to manage a high volume of airflow with a considerable saturation of H2 S. PureAir recommended using Sulphasorb FeXL™ blended adsorbent media because it can remove 45% of its weight in H2 S, making it an all-around more effective choice than carbon. It is a 50/50 blend of Sulphasorb XL™ and Sulphasorb Fe™.
