Passive Grease Interceptors (PGI) help food industries comply with the EPA Sewer
Pretreatment Regulations. PGIs are 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. PGI sizing and construction
conforms to recognized plumbing codes and meets, or exceeds, most municipal FOG
discharge requirements. They can be sized for greater volumes, storage capacity and
retention times up to 30 minutes.
Our standard PGIs are constructed from mild carbon steel, meeting ASTM specifications,
for superior structural strength and impermeability. Highland Tank's PGIs don’t crack,
leak or collapse under hydrostatic pressure. They are water tight and pressure testable
for leaks in both the factory and the field.
Advanced Corrosion Protection
Rigid specifications are followed to assure complete internal and external corrosion
protection including Highland Tank's HighGuard UL-1746 approved protective
polyurethane coating. An additional acid-resistant internal polyurethane lining assures
years of continuous service.
Aboveground cylindrical or rectangular interceptors and custom designs are also
available so that you can tailor volumes, compartments, inlets, outlets or baffles
to satisfy specific code requirements.
