Biofilter Biofiltration System
Harness the natural treatment action of vegetation and the filtration power of specially engineered soils with Marshalls Civils & Drainage Biofilter™, a unique biofiltration system that looks just like a normal tree box but provides innovative pollution control.
To by-passers what they see is plant or small tree growing through the decorative grating in a precast concrete cover slab at pavement level, however, a layer of enhaunced mulch on top of a unique soil filter medium delivers high levels of surface water treatment providing a high-performance, high-flow filtration that targets sediment, hydrocarbons, heavy metals, and nutrients to remove pollutants.
- No limitations in usage, Biofilter™ is suitable for residential or commercial settings, car parks and roadways and can retrofit to your scheme
- Suited to your requirements, Biofilter™ is available in either a pipe or kerbside inlet or, alternatively, water can be channelled directly from the surface
- Purify stormwater by filtering out pollutants such as dissolved, liquid and sediment bound hydrocarbons, gross and dissolved pollutants, sediment bound nutrients and heavy metals alongside very fine particles whilst remaining aesthetic
