Klargester Bypass Separator - NSBE010 - 5560M² Drainage Area

Bypass separators are used when it is considered an acceptable risk to not provide full treatment for very high flows, such as, where the risk of a large spillage and heavy rainfall occurring at the same time is small.

Typical applications include surface car parks, roadways and lightly contaminated commercial areas.
