Separators

Oil water separators are used to remove contaminants, such as petrol oil, grease and silt from water run-off, to prevent them being discharged into the watercourse.

Retain and separate

Our separators (often called interceptors) achieve two levels of final discharge into the drainage system. The bypass separator (class 1 discharge) is designed for larger, hard-standing areas, prone to hydrocarbon spillages. It retains hydrocarbon contaminants that enter the separator in the first 10% of any storm and achieves a final discharge to surface water drain of less that 5mg/l oil to water. Additionally, the bypass separator (class 2 discharge) offers a final discharge to surface or foul water drain and is 100ml/l oil to water.

The full retention separator is for more demanding applications such as fuel or storage points, plant hire equipment yards and vehicle dismantling workshops where the risk of hydrocarbon spillages is greater. It is also available to achieve both Class 1 and Class 2 discharge options.

Typical applications

It’s vital to install oil water separators where surface water runs off large standing areas. Typical applications would include:

  • Surface car parks
  • Road schemes
  • Garage forecourts
  • Industrial estates
  • Lightly contaminated commercial areas
