passive grease interceptors

highly efficient hydromechanical grease interceptors

Passive Grease Interceptors (PGI) help FSE and food production/processing industries comply with the EPA Sewer Pretreatment Regulations. PGIs are high-performance gravity grease interceptors designed to intercept and remove large quantities of sewer clogging FOG and oily food waste before it is discharged in a municipal wastewater treatment system.

The High-LINK® Integrated Systems couples Highland Tank’s superior steel tank products with state-of-the-art electronic management devices and proprietary software to provide real-time data to decision-makers. With our High-LINK® applications you will have the power to optimize the usage and transfer of all your liquid operations.  Learn more here.

Passive grease interceptors help food service establishments and food processing industries comply with EPA Sewer Pretreatment Regulations. PGIs are designed to remove large quantities of sewer-clogging fats, oils, and grease before it’s discharged into a municipal wastewater treatment system. Designed to accept gravity flow, PGIs retain wastewater long enough to allow liquefied grease to cool,separate, and congeal.
