Nijhuis - Model Type CPI -Gravity Separators

• Removal of free separable oils
• Removal of some sediment

• Different configurations possible
• System principle according to stokes law
• Standard choice of materials
• Special materials available on request
• Internals for concrete basin

Depending on the capacity and the required removal efficiency (based on droplet size) we will design the most suitable configuration.

The configuration of a CPI oil water separator is based on one or more trains. Each train will contain a number of bays and each bay will be equipped with a number of PPA plate packs.

The CPI unit is equipped with a corrugated plate pack (PPA) to increases the separation area. This results in an increased removal efficiency for the smaller oil drops.

In a CPI the liquid flows into the inlet channel. A flow distribution baffle will equalize the flow over the entrance to the PPA plate packs.

The floating oils are moved by a movable oil collection through (skim pipe), from where it flows to an oil collection sump.
