Blocks & Media
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. Learn more.
Mercury Reducing Block Filter
The new GreenStory GSGWF CB-HG, high-flow Point of Entry (POE) elements are easy to handle, install, and remove. A great new alternative to dealing with granular activated carbon (GAC) media, messy change-outs, and large tanks. GreenStory can match flowrates with a less capital-intensive solution and a fraction of the footprint of a tank system. Learn more.
Chlorine/Chloramine Block Elements
Our GSGWF CB-C/CM, high-flow Point of Entry (POE) elements are easy to handle, install, and remove along with being less messy than dealing with granular activated carbon media. A great new alternative to dealing with granular activated carbon (GAC) media and large tanks. Matching flowrates in a less capital-intensive solution and a fraction of the footprint of a tank system. Learn more.
Arsenic Reducing Block Filter
Our new GreenStory GSGWF CB-AS and AS(sm) Point of Entry (POE) block elements are a great new alternative to dealing with granular media, messy change-outs, and large tanks. GreenStory can match flowrates with a less capital-intensive solution and a fraction of the footprint of a tank system. The AS media is a blend of carbon and a ferrous adsorbent, with high selectivity and capacity for dissolved arsenic. Learn more.
Nitrate Reducing Granular Media
Our new GreenStory GSGWF Nitrate Media is unlike anything currently on the market. This media is specifically developed for selective nitrate removal from potable water in the presence of high levels of sulfate. Media is NSF/ANSI 53 certified to reduce nitrates to below the USA EPA enforceable regulation level of 10 mg/L. This media is available for use in residential drinking water and large municipal drinking water treatment systems. Learn more.
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. Learn more.
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. Learn more.
CTO Carbon Media Block Filter
Our GreenStory GSGWF CB-C filter block series will meet your smaller commercial and light industrial filtering challenges of chlorine taste and odor. A great new alternative to dealing with granular activated carbon (GAC) media, messy change-outs, and media tanks
