What is StormwaterSHALE™?

StormwaterSHALE™ is a rotary kiln-produced expanded shale, clay and slate lightweight aggregate or often called Activated Ceramic.  It is used for many reasons, but research and actual onsite results have proven why we blend it with our StormwaterBIOCHAR™.

StormwaterSHALE™ filtration media has up to 100 times the specific surface area than ordinary filtration sand and gravel.  This advantage combined with StormwaterSHALE™ lower density and excellent durability offer superior performance, increased volume flows and reductions in clogging or blinding over standard silica, granite or quartz granular media. StormwaterSHALE™ is manufactured throughout the United States and is a reliable, economical solution for water filtration in applications where sands and gravels are used. StormwaterSHALE™ is often the best choice in a variety of filter media applications, from storm water runoff to industrial wastewater filtration.

StormwaterSHALE™ excellent performance as a filtration media stems from its unique physical properties that are created during the vitrification process, all of which assure a strong stable media. They are:

• Increased surface area

• Deeper bed aeration
• Increased permeability

• Reduced weight

• Lower particle specific gravity

• Higher angle of internal friction

• Inert, Non-toxic
• Non-degradable
