filter storm water effectively for reuse or release
With the imperative for Water Sensitive Urban Design, Low Impact Development and Total Water Cycle Management, there has been increasing interest in using filtration systems as a solution for the treatment and reuse of stormwater and low flow industrial waste water runoff. Cascade has released a range of Reactive Filter Media that treat polluted stormwater and low flow industrial waste water.

Cascade Reactive Filter Media is custom designed for specific treatment applications using a blend of tailored components in defined proportions that are engineered for specific performance requirements such as contaminant removal, lifespan, hydraulic conductivity, compaction and plant growth. The Cascade Reactive Filter Media product range includes:
• Ecomedia
• Structural Grade Reactive Filter Media
• WaterClean Filter Bales 

Treatment of dissolved
contaminants is achieved by
chemical and biological processes
created by the selected components
in the filter media. These processes
include:
• microbial biodegradation
• sorption
• precipitation
• ion exchange
• volatilisation
• phytoremediation
