What is the difference between a Class 1 & Class 2 Separator?

We still have a few more questions to answer as regards Petrol/Oil Interceptors (Separators), next up; What is the difference between a Class 1 and Class 2 Separator?

A Class 1 Interceptor is designed to achieve a concentration of 5 mg/l of petrol/oil at discharge under normal conditions, includes a coalescer and a closure mechanism.  A Class 1 Interceptor is usually required for discharge to any surface water.

A Class 2 Interceptor is designed to achieve a concentration of 100 mg/l of petrol/oil at discharge under normal conditions and is normally used when discharge is to a foul sewer.
