Oil/Petrol Interceptors

aswafclear-logoPrecast concrete tanks designed and manufactured to EN 858         

  • European Union (EU) standard of manufacture guaranteed - EN 858
  • Prefabricated fibre reinforced 40 N concrete
  • No concrete backfilling required
  • Maximum sludge capacity
  • Flexibility in interceptor design and layout and location of inverts


Coalescence filter: High density polypropylene filter - removable through manhole        

  • Effluent quality: < 5 mg/l hydrocarbon
  • Easy access for maintenance


EN125 Non-lockable ductile manhole covers

  • Safety precaution in the event of an explosion
  • Concrete lids on the concrete tanks are designed to perform in heavily trafficked areas 

Interceptor: Stainless steel - automatic shut-off device

  • Safety precaution in the event of an explosion
  • Ensures full retention of oils
  • Corrosion Free
  • Manufacturer fitted inlet and outlet pipes ensure quick and easy on-site installation
Internal walls coated with epoxy resin paint      
  • Internal protected walls prevents corrosion
  • Units are delivered and assembled according to clients requirements


Generally interceptor/interceptor systems are used for:          

  • To treat waste water (trade effluent) from industrial processes, vehicle washing, cleansing of oil covered parts or other sources e.g. petrol station forecourts;
  • To treat oil contaminated rainwater (run-off) from impervious areas, e.g. car parks, roads, factory yard areas;
  • To retain any spillage, accidental or otherwise, of light liquids or oil/petrol and to protect the surrounding area

 

Interceptor Classes

Class 1: Coalescing interceptors are designed to achieve a concentration of less than 5 mg/l of oil under standard test conditions. They are used to remove very small oil droplets such as those arising from car-park run-off. Class 1 interceptors discharge directly into a storm water tank.

Class 2:
Gravity interceptors are designed to achieve a concentration of less than 100 mg/l of oil under standard test conditions. They are used where a lower quality requirement applies or for trapping spillages. Class 2 interceptors discharge directly into a foul drain which in turn drains into a sewage treatment plant
