H2S Control
About
H2S Control, a division of Heyward Florida Incorporated based in the Orlando area, designs and manufactures hydrogen sulfide odor control systems exclusively for municipal water and wastewater treatment facilities. The company offers four complementary product lines covering the full spectrum of vapor-phase H2S concentrations. The HIVON is a plant-level odor neutralization system that vaporizes and distributes HISCENT—a proprietary blend of all-natural essential oils—through a radial air distributor or piped network, handling 1,000+ CFM with no water, fog, or mist. The HIBOCS is a biological air scrubber featuring HIHP-98 high-surface-area synthetic media with a 10-year warranty, designed for lift stations and headworks with high H2S loads using non-proprietary nutrients and offering very low operating costs. The HICARB is a carbon-based up-flow vessel system using site-specific blended media for low-concentration H2S applications, and can be paired with HIBOCS as a polishing stage. The HIVENT is a passive, zero-energy unit that attaches directly to lift station vents, using natural wet-well airflow to neutralize odors with just 3–4 gallons of HISCENT annually. All systems feature corrosion-resistant construction (aluminum or FRP/polypropylene), stainless steel VFD-controlled motors, and carry 3-year component warranties. H2S Control is a member of WEF, FWEA, AWWA, and NRWA.
Key Products
