What is TPI separator?

Hence, TPI separator is a generic terminology used in such type of separators. The separator when used in separation of liquid – liquid phases (predominantly removal of free oil in oily water treatment) are called a TPI (Tilted plate interceptor) or a CPI separator.

​

TPI (Tilted plate interceptor) separators are used predominantly to separate free oil from effluent. TPI unit is deployed at the primary stage of wastewater treatment wherein plate packs are used as the main separation device.

​

Tilted Plate Interceptors are gravity separators utilizing the difference in specific gravity between two phases of liquid (predominantly removal of free oil in water) as the principle of separation. Gravity separation is a function of available surface area for separation.
