An arsenic and fluoride treatment plant located in Andrews, Texas, is to become the largest in the U.S., thanks to new technology that effectively removes fluoride from wastewater, provided by water and wastewater treatment solutions company Severn Trent Services.
The technology, called SORB 09, is based on fixed-bed absorption and is able to remove fluoride from water onto solid activated alumina. It has the capacity to treat 5,000 gallons of water per minute, which means that once it is fully functional the technology will allow the Andrews Fluoride and Arsenic Treatment Plant to operate at double the capacity of the curerent largest fluoride treatment plant in the United States.

SORB 09 will significantly improve water quality, as the treatment plant will be able to remove excessive amounts of fluoride and arsenic in water and bring levels to below drinking water standards of 2.0 ppm, according to a statement from Severn Trent Services. The technology was initially trialed at the treatment plant before a decision was made to have it installed, with the project to be commissioned in early 2015.
John Dyson, Americas sales director for Severn Trent Services, commented that fluoride removal was crucial for delivering high-quality drinking water, as elevated levels of the chemical could cause serious bone structure changes and discoloration of teeth.
