Grease interceptor

Fat separator to separate fats and oils from wastewater. The grease and oily dirt and rinse water from kitchens of the restaurant, hotel or catering must be disposed of through a grease trap. Governmental cafeterias clean before industrial wastewater before the water runs off into drains.
Function
 
 
Classic fat separator to complete disposal. It works on the principle of gravity: Fat floats above. Solids sink down. In the middle of the water.
Most fat separators operate by gravity and are constructed of a grease collector, a silt trap and a device for taking samples. In the system reduces the flow velocity of the wastewater. This fall, the settling and solids (food scraps) to the ground and settle in the sludge. Fat floats on its lower density, accumulates on the surface and can be removed. The oil and grease wastewater flows into the sewer.
In the wastewater-emulsified fats and oils (emulsion) pass through a grease separator, which works exclusively by gravity, generally unimpeded. In particular, in industrial establishments and regions where low effluent limits for oils and fats are required, more advanced treatment behind the grease separator is required. Conventional grease separators can not reach the required limits here. The use of a flotation plant to leave the limits lowers durable and safe.
Similarly, the waste water treatment is carried out in a biological treatment plant.
There are grease separator for installation into the soil and plants, which are freely distributed. Grease Trap for the underground installation are outside of buildings near the attack site to install the dirty water, in a place that is easily accessible for disposal of vehicles. Remote mounted grease separators must be in rooms above.
The nominal size of a Fettabscheideanlage depends on the quantity of waste water and is measured in liters per second.
Complete or partial disposal
 
 
Grease Trap for the partial disposal system Internships: fat and solids are collected in a handy plastic barrels.
Complete disposal: Classical grease separator should be emptied completely at least every four weeks by a waste management company, cleaned and then refilled with fresh water. Modern fat separators have a permanent connection to the drain pipe. The line is permanently installed within the building and ends with a coupling on the building's exterior. Usually the coupling is housed with a remote control in an on-wall box or in fully automatic grease traps is the management of automated. The fat separator can be included as unobtrusively from a tanker.


Part disposal: There are also fat separator, which separated sludge and grease in a handy plastic barrels and then disposed of. The operator may dispose of the collection barrels with the concentrated residues even when needed. Due to the demand management of the operating costs are generally lower than for complete disposal by tanker. In addition, the amount of Entsorgungsguts in this process is reduced compared to the complete disposal to around ten percent. The disposal of fats and solids in grease traps can also be done directly with partial disposal of a connection to a central Nassmüllentsorgung. Here, the separated substances are sucked along with other food waste to a central collection tank and then disposed of regularly.


Statutory requirements


The use of governmental cafeterias is governed by the standard DIN EN 1825-2 and DIN 4040-100 the national annex. It applies to companies with commercial distribution of food such as restaurants, hotels, canteens and snack bars, which accumulates in fatty waste water.
This provision appears in the effluent of association of municipalities, set the rules for the use of drains. For the water discharged into public sewage systems locally apply several requirements.
In industrial food processors (dairies, cheese factories, fish processing, flushing, kitchen waste treatment plants) is water with a high percentage of emulsified fats / oils. This wastewater is treated in governmental cafeterias by gravity is not always effective. A more advanced treatment may be necessary.
