When you need an affordable treatment box.


RainClear™ Component Stormwater Filter (CSF) is a highly effective, straight forward stormwater filtration system capable of treating large and sustained stormwater events.  Each RainClear CSF can be custom engineered for site specific needs and utilizes EarthLite Biochar Filter Media for stormwater.  This unique system is designed for treatment and removal of Turbidity (TSS) and Heavy Metals (Copper, Zinc, Lead, Iron, Aluminum).  Customers have also seen a 30% Phosphorus and a 33% Chemical Oxygen Demand (COD) reduction using the RainClear™ CSF.  See Additional Field Test Results at the bottom of the Test Results Page.
