Hydrocarbon separator class I
Designed to reach a concentration lower than 5 mg of oil per liter in standard testing conditions, these separators will be used when it is necessary to remove very small drops of oil. In order to improve the separation effect in the separator, a coalescing filter is installed in front of the exit connection.
When the water goes through the filter, small drops of oil combine to create larger drops that are detached afterwards from the coalescing material and rise to the surface. A special intake system produces a buffer-flow effect in the separator. This slows the intake flow and distributes it efficiently in the separation space. The heavy particles go in the lower side and are separated and the easy particle rise in the upper side and are separated there.
Hydrocarbon separator class II
Designed to reach a concentration lower than 100 mg of oil per liter in standard testing conditions, these separators are ideal for usage in case it is applied a lower quality request.
Hydrocarbon separator with by-pass
By-pass separators treat entirely all the debits generated by the rainfall rates up to 6.5mm/hour (99% of rainfalls). These separators are used in parking areas when it is considered an acceptable risk the insurance of a complete treatment for high debits. For example, when the risk of a significant hydrocarbon leak and heavy rains at the same time is small.
