STORMTECH ISOLATOR ROW
The Isolator™ Row is a stormwater filtration zone that removes almost all particles less than 40 micron and a very high percentage of associated pollutants typically found in Stormwater.
The Isolator™ Row is a stormwater filtration zone that removes almost
all particles less than 40 micron and a very high percentage of associated
pollutants typically found in Stormwater.
The Isolator Row™ can be used as a Gross pollutant (GPT) or other primary
pollution treatment device if the potential pollution load is low or when a shallow
or low expense GPT is required.
The Isolator Row™ is more commonly used as a secondary treatment process
and particularly used in conjunction with the detention and storage of stormwater
to minimise pollution build up in the entire storage area.
The Isolator Row™ is designed to allow for easy inspected from the surface
while isolating sediments to a relatively small portion of the detention or storage
system, and thereby reducing cleanout costs.
Many systems on the market cannot be maintained and others would require costly
clean out with confined space safety requirements to consider.
The Isolator Row™ consists of a row of Stormtech™ arches which have
an open bottom and engineered perforations in the outside corrugations of the
arch which allows the stormwater to pass both vertically and horizontally through
the filtration geotextiles which envelopes the entire row.
The Isolator Row™ is configured to enhance the settling of fine sediment
that is not captured by any pre-treatment devices (if installed). This sediment
is then unable to exit from the row and is effectively “isolated” in
the row of chambers, providing a zone that can be easily inspected and simply
jetted out when required using commercially available jetting services.
The Isolator Row™ system has been university tested with a reported TSS
capture performance of 94 to 97%.
