The HIBOCS odor control vessel from Heyward Florida is a biological air scrubber system designed to remove vapor phase odorous gases, primarily hydrogen sulfide. Typical applications are lift stations or plant headworks with high-level H2S and airflow volume. The system is comprised of a fiberglass or polypropylene vessel, which contains HIHP-98 high-surface-area synthetic plastic media. All system control panels are prewired and plumbed and mounted to the control skid for quick and easy installation. The FRP or corrosion-resistant cast aluminum blower is powered by a stainless steel washdown/inverter duty motor that is variable-frequency drive controlled for precise airflow and quiet operation. Since the media life expectancy is the life of the system, and the nutrient chemicals are nonproprietary, the operating cost is low. 407-628-1880; www.h2scontrol.com
