A new dust-free process to improve GreensandPlus filtration media has just been announced by the Inversand Company. The dust-free media ensures that all GreensandPlus installations now require very minimal backwashing, perhaps no longer than 10 minutes. This is especially meaningful when compared to the 60 to 90 minute time allotment that may have been necessary prior to this development. The media removes iron, manganese, arsenic, radium, and hydrogen sulfide from water. It carries a WQA Gold Seal Certification for compliance with NSF/ANSI 61.
