SORB 33 arsenic adsorption system
For most applications, the SORB 33 arsenic adsorption system is the simplest and most cost effective solution on the market—compared to reverse osmosis, ion
exchange, activated alumina, coagulation microfiltration and others. 
In this simple pump-and-treat adsorption system, the contaminated water passes through a robust granular ferric oxide media, Bayoxide® E33, developed exclusively for Severn Trent by Bayer AG. As the water passes through the media at the wellhead, the arsenic is adsorbed and removed to a level below the drinking water standard of 10 micrograms per liter (μg/l).
