CrumRubber™ patented technology is a biological system which utilises inorganic filtering media and specialized bacteria to remove high level of H2S converting it into sulphate.
The technology has been studied to reduce gases concentration prior to combustion gas engine in order to preserve its availability (time life), increase oil change and decoking intervals and reduce reliance and costs associated with frequent activated carbon change outs.
Typical removal efficiencies for levels of H2S from 10 to 4000 ppm ranged till 98%. CrumRubber™ technology could be also suitable as pre-treatment stage of traditional air treatment solution for removal of chemical compounds as ammonia, amines, VOCs and odor.
The filtering media could be regenerated by continuous or intermittent flushing with water. CrumRubber™ can be supplied as a skid-mounted modular system made by high grade corrosion resistant material equipped with removable covers for media replacement.
