The dry, crystalline granular Bayoxide® E33 media was designed with a high capacity for arsenic, providing long operating cycles and low operating costs. The media’s life expectancy is dependent on site-specific water quality and operating levels. Media is filled into the vessels from sacks by gravity or by hydraulic educting. The exhausted media is classified as non-hazardous in the United States and can be sent to a landfill, passing TCLP or landfill leachate requirements. Spent media can be removed hydraulically or by vacuum.
Local regulations in other countries, such as the European Union can differ from the U.S. and will therefore affect disposal routes. It is important that users meet the disposal requirements for spent media to ensure compliance with local and national legislation.

Adsorption tests on Bayoxide® E33 have shown that it will adsorb a range of ions in addition to arsenic, which will be adsorbed in preference to these other ions. Under high pH conditions, high levels of certain interferants can reduce the media’s adsorption capacity for arsenicphosphate (>1.0 ppm) and silica (>40 ppm) can present interference and reduce the media’s adsorption capacity for arsenic.
