Pollution Management
Increasingly, regulations and design guidance highlight developer's obligation to mitigate the risk of pollutants emanating from contaminated run-off from hard standing surfaces. The most common diffuse pollutants are hydrocarbons and contaminated silts. The Permavoid system offers an integrated technique for the source control treatment of polluted run-off using advanced geotextiles and flotation techniques such as:
Permachannel – A linear treatment system, with a catchment area of 30m², which can reduce hydrocarbon pollution below 5mg/l.
Permaceptor – A combined run-off collection, silt/oil interceptor and treatment system with a catchment area of 150m².
Permavoid Biomat– Has been specifically designed to remove hydrocarbon pollutants from surface water and is capable of retaining 56g of oil per m².
Permafilter Geotextile – A non-woven, needle punched geotextile designed to retain up to 6l of oil per 10m².
