Tilted Plate Interceptor (TPI) plate packs or also known as Corrugate Plate Interceptor (CPI) are oil separators used to remove oil mass in wastewater treatment and industrial uses. TPI oil water separator is a blend of gravity separation and coalescence to get rid of free-floating oil from effluent wastewater.
Ravi Enviro Industries Pvt.Ltd is a leading TPI oil separator manufacturer in Taloja. Our tilted plate interceptor oil water separator is predominantly used in a primary stage of wastewater treatment. These plate packs are used as primary separation equipment, designed with specific spacing and alignment to allow solids to settle at the bottom so the oil rises and coalesces on the surface. Our TPI plate packs come in single and multiple packs for use in industries like oil & gas, petrochemical, water & wastewater treatment, power, steel, mining, dairy and pharmaceutical sectors.
TPI Typical Removal Rates
| Oil Removal | 50->99% |
| Residual | 5-20 ppm slop oil |
| TSS removal | 80-90% |
Key Features of TPI Plate Packs
- The TPI oil separator works on the principle of density difference and is equipped with internal baffles and chambers that improve the oil-water separation process.
- Equipped with a secondary coalescer screen that holds oil particles up to 20 microns.
- It requires low space and low maintenance costs as there are no moving parts
- It offers high efficiency and capacity along with combined with compact volume
- Its solid build allows it to withstand extreme weather conditions and the composition of wastewater & other liquids.
- REIPL’s in-house team of engineers can design and manufacture TPI separators in steel/carbon steel and skid mounted basins with manual and automated functionality.
Core Components of TPI Plate Packs
- Inclined Plates: These plates are the key parts of the TPI oil separators. This is the surface where the oil droplets and suspended particles are trapped and coalesced for easy separation from liquids.
- Separation & Coalescence: With the wastewater stream flowing through the inclined plates, the oil droplets, grease and suspended particles that come in contact with the plate surface and accelerates the separation process.
- Outlet Component: The treated water is gathered from the lower part of the TPIs and is either discharged or sent for further treatment.
Applications of TPI Plate Packs
- Portable & process water pre-treatment
- Food & beverage industry
- Oil & petrochemical industry
- Steel and mining industry

Frequently Asked Questions
1. What is the function of TPI?
~ TPI plate packs are used for oil-water separation by employing gravity separation and coalescence.
2. How does the TPI plate pack work?
~ The TPI plate pack uses inclined corrugated plates for the separation of oil and solids from wastewater through the mechanism of gravity and coalescence.
3. What are TPI plates typically made of?
~ The TPI units are manufactured in metallic tanks made from corrosion-resistant materials with protective coating.
4. What is the typical removal rate for oil droplets?
~ These units can remove 50% to 99% free-floating oil from wastewater streams depending on factors like type of oil, droplet size and TPI plate design and operating conditions.
5. How to choose the right TPI oil separator for your application?
~ To choose the right TPI plate pack, take into consideration your specific application requirement, including flow rate, fluid mixture, separation efficiency and available space. At REIPL, as a TPI oil separator supplier in Taloja, we provide clients end-to-end assistance to choose the right equipment for specific applications.
