This firm’s Environmental Systems Div. (ESD) has launched its newest dry-scrubbing media, Odorcarb Ultra, which is said to be the first activated alumina media with the ability to remove 0.3 g of hydrogen sulfide per cubic centimeter of media. Odorcarb Ultra replaces Odorcarb II as the primary component of ESD’s odor-control applications. Similar to its predecessor, the improved media also contains the patent-pending Media Life Indicating Pellets. These blue pellets (photo) appear white after chemisorption to distinguish new media from spent media. — Purafil Inc., Doraville, Ga.
