passive grease interceptors
highly efficient gravity 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.

underground cylindrical
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.
