Oil - Water Separators

Intercept fuel / oil before it enters sewer or drainage

Designed to meet EN858 standards, Molloy's range of interceptors each use high quality precast concrete tanks. The interceptors are designed for a wide variety of uses:

Full retention, By-pass and Forecourt separators

Flexible and robust designs, easy to maintain

...

Full retention

Full retention separators treat the full flow that can be delivered by the drainage system.

...

By-pass

Allows a flow in excess of maximum permissible effluent flow to bypass the interceptor.

...

Forecourt

Specified to retain on site the maximum spillage likely to occur on a petrol filling station.
