System removes arsenic, iron and manganese from water
Filtronics Inc. of Anaheim, Calif., announced it is one of the first companies to receive approval from the Texas Commission on Environmental Quality (TCEQ) for its treatment technology for the removal of arsenic, iron and manganese at the filtration rate of 10 gal per minute per sq ft.
According to Filtronics, this high filtration rate is significant for several reasons. Conventional systems must operate at a lower rate to achieve comparable results, often 3 to 5 gal per minute. The benefit is substantial savings in the initial capital investment for smaller, compact equipment and a small footprint. Cost savings are realized by the construction and use of smaller facilities and the increased water production from the high filtration rate with less waste and handling. The smaller filter size also translates into lower wash water requirements and further enhances the backwash-to-filtration ratio for a more efficient system.
TCEQ issued its approval early last year. Filtronics has two filtration systems operating that are continually exceeding the effluent requirements imposed by the U.S. Environmental Protection Agency and the TCEQ.
