ACO Grease Trap and Interceptors
Fat, oil and grease generation
A significant problem for kitchen and food preparation areas is the collection
of fat, oil and grease within the drainage system. These substances not
only have a major effect on the performance of any internal or local external
drainage system, but can also have a major impact at regional level: water pollution,
obstruction of drainage infrastructure and reduced efficiency at sewer plant
are all possible occurrences. Legislation, either existing or in development,
will place increasing responsibility for control at source.
ACO Building Drainage provides a wide range of grease trap systems to assist
with prevention. The systems provide hygienic, effective methods of dealing with
these substances with a selection of accessories to suit all applications.
Biological grease management - The product
ACO's new Biological Grease Traps are designed to suit all food production facilities
and are available in two ranges: 'Below Ground (BGP)' and 'Free Standing (FS)'.
The BGP range is manufactured from robust, lightweight and corrosion resistant
polypropylene. Designed for higher capacity applications up to 1000 meals
per day, the BGP units are ideal for internal or external use where space is
limited or invert levels dictate a below ground installation.
Manufactured
in either stainless steel or polypropylene, the FS range provides the most versatile
and compact solution for small to medium sized facilities. The
stainless steel traps are designed for hygiene-critical applications or for installations
where appearance is important. The cost-effective polypropylene traps
provide equally high performance in applications where finished appearance is
less critical.
Biological grease management - The process
All ACO Building Drainage biological grease traps work on the same principles:
a biological activator is periodically injected into the connecting drainage
pipe upstream of the trap. The mixture of contaminated water and activator flows
into the trap and through a sediment bucket. The sediment bucket removes any
larger particles that may be present in the drain waste. It is important to note
that the sediment bucket volume is limited, therefore any significant amounts
of debris should be removed before entering the grease trap. The physical capacity
of the trap provides a separation area where relative density differences allow
finer solids to settle to the trap floor and less dense FOGS to rise to the surface.
Separation occurs relatively quickly, thereby allowing less contaminated water
to flow to the outlet drain during periods of intense use. Floating FOGs are
gradually broken down by biological activators. The resulting liquid is then
discharged to the sewer.
