How it Works
HOW IT WORKS
1 Grease , solids and wastewater from the kitchen enters the Grease Guardian.
2 Solid food waste is caught in a removable strainer.
3 The grease passes into the middle chamber through slots in the bafe wall
where it remains trapped. With the assistance of a heater the grease separates
from the wastewater and rises to the surface.
4 The liqueed grease adheres to the rotating skimming wheels.
5 The grease passes down a scraper blade into a collection container where it
can be removed and disposed hygienically.
6 The treated water exits under a bafe wall and through the outlet to drain.
7 Kitchen waste water drain
The FM Environmental Grease Guardian series automatic grease removal unit (GRU)
is a totally engineered system for separating free oating grease and oils from
drain water ows. The separated grease and oils are trapped within the stainless
steel tank and are automatically recovered by the system. Only the “cleaned”
water is allowed to pass through the system into the drain lines. Each unit also
separates solid food waste into a removable basket. The Grease Guardian can
be used in a wide variety of applications from restaurants and food processing
operations to many types of industrial operations. Appliances that can be directly
connected include utensils sinks, pre-rinse sinks, combination ovens, and wok
cookers.
Use of the Grease Guardian assures that costly sewer surcharges and nes are
minimised or eliminated through efcient separation and removal of the grease
and oil. In addition, rapidly escalating pumping and disposal costs, which are
associated with conventional grease traps or interceptors are also reduced or
eliminated. The recovered grease and oils are virtually water free so they can be
collected by a local rendering Company or recycler.
