Description:
Removal of low-level arsenic from drinking water sources has attracted significant attention recently. Existing technologies are considered effective for this purpose; however, they fail to meet the criteria of reliability and simplicity in operation for small drinking water treatment facilities. More importantly, existing technologies may require additional post-treatment to achieve safe disposal of solid and liquid residual by-products generated from these operations. Therefore, a simple, cost-effective and user-friendly technology is needed for small drinking water facilities to comply with the forthcoming regulations on arsenic removal. An inorganic mixed-oxide adsorbent has demonstrated its unique affinity and high capacity to arsenic contaminants. Further, the spent adsorbent can be disposed of in an environmentally friendly manner. In this project, Media & Process Technology, Inc., will develop a chemically bonded, pelleted product from this unique material via a microengineered approach. Media & Process Technology, Inc., believes that this microengineered adsorbent can overcome the technical barriers of existing technologies and will be an ultimate solution specifically designed for arsenic removal for small drinking water treatment facilities.Supplemental Keywords:
