New Product Release - Gross Pollutant Trap

Our newly released Gross Pollutant Trap is a baffled pollutant trap with a high flow by-pass. It is designed for use in open areas where trash and other debris cannot be controlled and a potential for minor quantities of hydrocarbons exist. Typical applications are the treatment of stormwater run-off from large open areas such as carparks, where minor oil leaks from motor vehicles have the potential to create a risk to the environment.

The Gross Pollutant Trap comes standard with a heavy duty Class ‘B’ grate and frame. Heavier classes can be supplied if required at an additional cost.

The Gross Pollutant Trap has a controlled flow rate through the silt basket where trash and silt are removed. Runoff then enters the main chamber and exits under the baffle, retaining any hydrocarbons that may be present. If the rain intensity exceeds the treatable flow rate the high flow by-pass allows excess runoff to exit directly via the baffle.

Our Gross Pollutant Trap has an efficiency of greater than 99% for the capture and retention of silts and solids larger than .3mm. This exceeds most Councils requirements for a stormwater quality improvement device (SQID). Typically Local Councils require a SQID to capture and retain specified pollutants during a 3 month average rain event - for South East Queensland this is a storm event of 60mm/hr. At this rain intensity the BPT600 can treat the runoff from a paved area of approximately 330sq metres.
