Static Oil Separators

Description of System.

In static oil separators, suspended particles whose specific weight is different from that of the water undergo sedimentation and oil separation by gravity.

This is one of the most commonly used processes in wastewater treatment in order to obtain clarified effluent.

To further purify the water, the liquid mass is channelled through a special adsorbing coalescence filter which traps any small traces of oil and grease that might have escaped the first treatment stages.
The oily substances which are separated are collected in the internal storage chamber.

To ensure retention of the oily substances, an automatic closing device is fitted on the outlet pipe which, when the light liquid accumulated on the surfaces reaches a certain level, closes the outlet channel, preventing the oil from spilling out.
