CPI (Corrugated Plate Interceptor) is a widely used oil-water separation equipment in industrial wastewater treatment systems. Many industrial clients ask how CPI improves separation efficiency in oil-containing wastewater.
The system uses a series of corrugated inclined plates installed inside a tank. These plates reduce the settling distance of oil droplets and suspended solids, allowing faster separation.
Oil droplets naturally rise due to lower density, and CPI enhances this process by increasing coalescence and separation surface area.
CPI systems are commonly used in refineries, petrochemical plants, mechanical workshops, and marine wastewater treatment applications. They are often used as a pre-treatment step before biological treatment systems.
One of the main advantages of CPI is low energy consumption. It relies mainly on gravity separation, which reduces operational costs.
However, CPI is only effective for free oil and non-emulsified oil. When emulsified oil is present, pre-treatment such as DAF or chemical breaking is required.
Maintenance includes sludge removal and inspection of plate spacing to prevent blockage.
CPI is often integrated with other wastewater treatment equipment to improve overall system performance.
In conclusion, CPI is a cost-effective and energy-efficient solution for oil-water separation in industrial wastewater treatment systems.
