The CPI(corrugated plate interceptor) Oil Separator is an oil-water gravity separator, developed with Shell’s technology, and is suitable for oily wastewater treatment. CPI Oil Separator enables high efficiency gravity separation with corrugated plates, providing excellent treatability with a high flow rate. The simple structure makes it possible to reduce the construction cost and facilitates maintenance.

1. The corrugated plates are located at short intervals, providing high oil-water separation efficiency. This makes it possible to stably treat rainwater even when the amount of rainwater treated is two or even four times larger than usual.
2. Compared to the PPI (Parallel Plate Interceptor), the CPI Oil Separator requires about 2/3 the installation area.
3. Compared to the PPI, the CPI Oil Separator has a relatively low construction cost.
4. The simple structure facilitates maintenance.
5. The CPI Oil Separator uses a molded synthetic resin that is highly resistant to corrosion, acid, and alkali, such as FRP, and is suitable for water quality.
6. The compact structure eliminates any concern about plastic deformation.
