High-Efficiency Corrugated Plate Interceptor (CPI) for Oil-Water Separation

The corrugated plate interceptor (CPI) is a highly efficient oil-water separation device. Its core technology is the corrugated plate gravity separation process, which removes unemulsified free oil and dispersed oil from oily water. The CPI combines gravity sedimentation and coalescence technologies: Firstly, it uses gravity sedimentation based on Stokes' Law to remove oil, employing a carefully designed flow rate to maintain laminar flow and prevent flow disturbances; Secondly, it utilizes our proprietary coalescing coating material technology to specially treat the surface of the corrugated plates, enhancing their oleophilic and hydrophobic properties, thereby effectively promoting phase separation.

Flow-through coalescing media is a standard feature of our high-performance oil-water separators and can also be used to replace or retrofit existing tanks to improve performance and increase flow rates.  Our polymer secondary coalescing media provides a high-density surface area in a small cubic area, which can be added to your existing media or used in conjunction with flow-through coalescing media to increase the capture of small droplets for optimal oil-water separation.

We offer custom design and retrofit services to meet your project needs, allowing you to upgrade existing tanks to our high-performance design or create a completely new design/build solution tailored to your facility and application requirements.
