Grease Interceptors – Generic Types
Hydromechanical Grease Interceptor VS. Other Grease Interceptors
The grease management industry has developed signicantly in the past decade
with not only more advanced and improved products but also development of
performance standards and harmonization of common terms and references.
Traditionally the term “Grease Trap” was commonly applied and is still
used in the industry today. This term is progressively disappearing
from nomenclature and technical references based on an industry wide
recognition that the term “trap” would suggest the presence of a water seal,
integrally located within the interceptor. This practice substantially ceased
many years ago, modern interceptors being designed to be installed in
conjunction with external water seal traps as a standard part of the system.
In addition to this clarication, with publication of the 2006 UPC plumbing code
three generic types of Grease Interceptor were introduced and have since become
the industry standard for designating the type of interceptor being considered.
Generically the application of a Grease Interceptor regardless of type is
dened as follows:
Grease Interceptor: “A plumbing appurtenance or appliance that is installed in
a sanitary drainage system to intercept nonpetroleum fats, oil, and grease (FOG)
from a wastewater discharge.
Specic characteristics then dene the three types of Interceptor:
Hydromechanical Grease Interceptor (HGI)
“An HGI is sized by ow rate (GPM) and qualied separation/retention eciency,
validated against National performance Standards. An HGI incorporates a dened
means of ow control, acts to entrain air to inuent, includes interior baing, or barriers
in combination or separately, working to promote hydromechanical separation. HGI’s
are generally installed inside the facility they serve.”
Gravity Grease Interceptor (GGI)
“A GGI is characterized by volume, minimum 30 minute retention time, bae(s), not
less than two compartments, a total volume of not less than 300 gallons (1135 L), and
gravity separation. If not recognized by an ocial body, a GGI will be designed by a
registered professional engineer. GGI’s are generally installed outside the building they
serve and buried below grade.”
Grease removal Device (GRD)
A GRD is a hydromechanical grease interceptor that mechanically removes non-
petroleum fats, oils and grease (FOG) from the separation chamber, the control of which
is either automatic or manually initiated and involves maintaining a liqueed state of
intercepted FOG by heating. GRD’s are installed inside the facility they serve.”
