GreenStory Global Water Filtration GSGWF CB-PF, high-flow point of entry (POE) PFAS reducing block filter

PFAS Reducing Block Filter

Our GreenStory GSGWF CB-PF, high-flow Point of Entry (POE) filter block element has been NSF P473 certified to reduce PFOA & PFOS over its entire filter life. A great new alternative to dealing with granular activated carbon (GAC) media, messy change-outs, and large tanks.  GreenStory can match flowrates in a less capital-intensive solution and a fraction of the footprint of a tank system.  When exhausted, the PFAS removal element will be returned for disposal via incineration.

GreenStory Global Water FIltration GSGWF Arsenil AS media - arsenic and fluoride reducing granular media

Arsenic & Fluoride Reducing Granular Media

Our new GreenStory GSGWF ArsenilTM AS media has twice the capacity for arsenic as the leading iron oxide or titanium-based materials.  The AS media is a ferrous adsorbent, with high selectivity and capacity for dissolved arsenic and fluoride, with a preference over common competing ions.  AS media absorbs both trivalent and pentavalent arsenic, as well as fluoride and other oxy-anion contaminants.  ArsenilTM AS  performance will increase your existing system rated gallonage with the same cubic feet of media.  For new installations, the media tank volume requirements can be reduced, shrinking the filter system’s physical size.  ArsenilTM AS media carries NSF 61 approval.

BTS-u & BTS-smx Media Suspended Solids Removal

Our GreenStory GSGWF BTS product is the ultimate media for superior water filtration in Gravity Flow or Pressure Systems.  BTS media is an all-natural mineral consisting of a high-surface-area and large internal void space for effective filtration of silt and colloidal particles.  The pressure drop (head loss) in clean media is less than in typical silica sand type filters sized 0.45-0.55mm.  This media has a surface area over 100 times greater than sand and provides the same filtration mechanisms (mechanical straining, sedimentation, and flocculation) but in addition, it offers physical adsorption, electrostatic adsorption, and ion exchange.  The loading capacity on the BTS media is much larger than silica sand, thus allowing less frequent backwashing of the media and reducing wastewater.  BTS is proven effective in gravity flow and pressure systems and can replace the sand or mixed media.
