H2S Removal
FACILITY TYPE: Water Treatment Plant
LOCATION: Jackson, Mississippi
EQUIPMENT/MEDIA USED: Biologically Engineered Adsorbent Scrubber Technology Bioscrubber (BEAST™) and Sulphasorb Si™ adsorbent media
PROBLEM: The process of dewatering digested biosolids at the water treatment facility releases H2S gas, which has a very distinct and unpleasant odor. The facility needed a solution to remove the odorous gas from the air and stop the odor complaints it was receiving from surrounding neighborhoods.
SOLUTION: PureAir determined the most efficient solution to remove the high volume of gases emitted at the facility is its BEAST™ (BST-2100). This multi-stage scrubber is specifically designed for applications with very high H2S levels and offers fully remote monitoring capabilities. Since its installation, the BEAST™ bioscrubber has successfully removed 99.9% of H2S from the air and the odor complaints have stopped turning the customer into a good neighbor.
Air Quality Monitoring Tools
The Electronic Bed Monitor (EBMv2) is the only tool on the market that continuously monitors changes in the life of the adsorbent media in real time. Its electronic notification system alerts users when media is partially and completely consumed.
LOCATION: Ottawa, Canada
EQUIPMENT/MEDIA USED: 3 – V-Bank Transition (VTS) and Sulphasorb XL™, CPS Blend, Ammoniasorb®, and Omnisorb, Electronic Bed Monitor
PROBLEM: Remove H2S, Ammonia, and other VOCs released into the air during the water treatment process
SOLUTION: PureAir customized each VTS to have four beds of chemical adsorbent media rather than the standard two or three beds. To guarantee optimum and long-term system performance, which includes no escaping odors, ROPEC also decided to install an Electronic Bed Monitor (EBM) in each VTS. EBM’s measure the remaining life of the adsorbent media in real time to ensure there is no breakthrough.
Other Industrial and Commercial Odor Control Applications
PureAir is experienced in removing odors at a number of other commercial and industrial applications, and our custom designed units and high quality media can fit various space requirements, while removing all odorous gases.
Food and Beverage Processing Facilities:
FACILITY TYPE: Dannon Yogurt Plant
LOCATION: Ohio
EQUIPMENT/MEDIA USED: Vertical Bed System (VBS) filled with Sulphasorb XL™, CPS12 Blend, and Omnisorb chemisorbant media
PROBLEM: Eliminate odor complaints from surrounding neighbors created by their wastewater plant that manages the cream waste by-product used to make Greek Yogurt.
SOLUTION: PureAir installed a VBS after the underperforming biofilter that was only removing 90% of the H2S and none of the other odors. Three chemisorbant media were used to remove H2S, Methyl Mercaptan, and Dimethyl Disulfide. Since installation, Dannon reported that all odors were removed, and customer complaints were eliminated.
