Advantages Over Conventional Biofilters

nnnn

Hydro Filterra™ is similar in concept to conventional

nnnn

bioretention filters or rain gardens. However, unlike these

nnnn

devices, it does not require a prolonged period of contact

nnnn

time to remove pollutants. Instead, specially engineered

nnnn

filter media within the Hydro Filterra™ allows high volume

nnnn

throughput whilst achieving high pollutant removal. This

nnnn

allows for a more compact device, with the surface area

nnnn

of the Hydro Filterra™ only 0.2 to 0.3% of the drained site

nnnn

See the table below for typical pollutant removal.
