Fox - Model BPT600 - Gross Pollutant Trap
A Fox Model BPT600 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. The Fox BPT 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.
The Fox BPT600 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.
The system will be installed by others in accordance with the instructions provided by Fox Environmental Systems at the time of ordering. Please refer to our drawing for the BPT600 specification details and drawing A4-INST-1016 for typical installation requirements.
