Restaurant
owners are under fire for discharging excess oil and grease
to the sanitary sewer in many locations around the U.S.
some because their grease traps are not properly maintained
and others for lack of an adequate grease trap system. Maintaining
a restaurant grease trap is expensive, whether you are performing
the work yourself or having a vacuum truck company pump the
trap. The frequency of cleaning depends on many factors; size
and location of the grease trap and even the menu items prepared
by the kitchen.
Larger
grease traps (3-500 gallons) are usually maintained by a professional
service, costs can run into hundreds of dollars each month.
Added to the service cost you must consider the smell and
mess the customers may be exposed to.
An
Example
Two
side by side sit down restaurants located in a major shopping
mall, with high customer volume, were experiencing grease
build up in their grease traps. The grease traps were being
pumped every three months with a one to two foot grease caps
and heavy bottom solids in both grease traps.
BD-R
in Action
Our
Biodigesters for restaurant use were added to decrease the
grease cap and bottom solids.
To
test the effectiveness, only one of the restaurant grease
traps was treated while leaving the other restaurant’s grease
traps untreated to allowing us to form a comparison.
The
Results
After
three months both grease traps were pumped. The untreated
grease trap had a two-foot grease cap and heavy bottom solids
as before. The BD-R treated grease trap had only a slight
oil sheen on top of the liquid and had no bottom solids.
This
test proved that treating a grease trap with Biodigesters
not only reduces the grease cap and bottom solids but also
provides the benefits of a faster, easier, more cleanable
slurry. The grease trap capacity increased and the overall
efficiency of the grease trap improves by breaking down and
consuming the grease cap and bottom solids.
