Grease separators are used wherever animal or vegetable fats are carried into waste water. Commercial kitchens must have pre-treatment plants to ensure that solids and liquids that release harmful or unpleasant vapours or interfere with operations are not discharged into the public sewerage network. Otherwise the fats, oils and grease (FOG) contained within greasy waste water put the pipe system, drainage equipment and wider sewer network at risk. Fats, oils and grease are deposited with other wastewater components on the walls of the pipes and can lead to corrosion, blockages and unpleasant odours.

In businesses which generate waste water containing fats, oils and grease, grease separators should be installed in accordance with EN 1825.

For example, local authorities demand the installation of grease separators in:

commercial kitchens,
hotels,
cafeterias,
and canteens.

Grease separators work using gravity. Their different densities are used to separate the fat/oil from the wastewater. Animal and vegetable fats and oils have a lower specific gravity than water, which makes them rise to the surface. Depending on the grease separator system the separated substances can be disposed of correctly either separately or together with the total contents of the grease separator.

ACO Building Drainage offers their customers grease separator plants for free-standing or underground installation. In addition, we distinguish between full disposal and partial disposal plants. With full disposal the content of the separator is removed, cleaned and filled by a disposal company at regular intervals. With partial disposal the separated grease/oil as well as the sludge are collected in separate containers and disposed of separately.

ACO offers comprehensive range of nominal sizes of grease separators for both free-standing installation and below ground installation that are not available from other manufacturers. This means the perfect solution can be provided according to the level of waste water to be dealt with and there is no need to take the next highest nominal size for reasons of capacity, which saves money and space.

In order to reduce microbes, very hot water is used for rinsing in hospitals, catering facilities and homes for senior citizens in particular, with the separator logically being exposed to that same water. The same applies to the emptying of tilting frying pans and boilers. Grease separators made of stainless steel are ideally suited to such tasks and can prevent deformations in the long term.

Stainless steel belongs to building material class A1, so it does not represent any fire load or fire hazard. A kitchen planner should aim to reduce the fire load in a building as far as possible and guarantee high safety standards.

Furthermore, irrespective of the material, a large selection of extension stages are available, each of which can increase operational and cleaning safety.

This is achieved by additional components such as systems for inner cleaning, as well as filling devices and disposal pumps. Measuring devices are also able to monitor operating conditions and reliably forward them to corresponding monitoring devices.

Different separators are available for the various applications found in the field, which are manufactured specifically for particular requirements or building situations, whether they are found in new buildings or renovation projects. ACO provides grease separator systems as a complete solution for a range of application areas ranging from snack bars right up to large commercial and industrial kitchens.

Hygienic features of ACO grese separator

Hygiene standards in commercial kitchens are getting more stringent all the time. ACO has taken on this challenge and come up with grease management solutions specifically tailored to these needs.

Plants available in stainless steel
Effective inner cleaning to remove all residue in the separator
Homogenising and cleaning in a single step
Hydro-mechanic high-pressure inner cleaning (175 bar, 360°)
Neutralisation of odours
Cover can remain closed during inner cleaning

Safety is writ particularly large in commercial kitchens, as work needs to be performed quickly and safely. Another essential safety aspect is fire protection and fore example ACO Grease separators made of stainless steel meet all requirements in this regard.

Plan with certainty, thanks to a huge choice of materials
Solutions for all types of construction
No additional fire load introduced to the building thanks to the use of stainless steel (building material class A1)

Cost pressure during the planning phase and efficiency improvements during day-to-day operation only seemingly contradict each other.

Grease level detection through measuring the grease layer
GSM module for signal transfer
Avoidance of the heavy polluter surcharge
