passive grease interceptors

highly efficient gravity grease interceptors

Passive Grease Interceptor How It Works

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.

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.
