This device is designed for catching oil and grease, that contains wastewater from kitchens, food-processing operations, meat-processing operations, etc. It catches and separates the grease as prevention from silting and blockage of the sewerage system. The wastewater from toilets and bathrooms cannot be drawn into the grease trap. Basic
technological parameters of the grease traps are designed in accordance with German DIN 4040, Austrian ÖNORM B 5103 and with prEN 1825-1 Traps, part 1.

Grease traps AS-FAKU FOZ/AUTO and FOZ/MANUAL are mechanical devices for separating vegetal and animal oils. Type MANUAL is equipped by manual control, type AUTO by programmable control automation.
Devices are produced from PP, PE or stainless steel class 1.4301 or 1.4571 according DIN.
Constructional proposal AS-FAKU FOZ is made according EN 1825-1 , ÖNORM B5103 a DIN 4040.
Advantages of AS-FAKU FOZ/MANUAL and AUTO
Low weight - all parts is possible transport and assemble by hand. All dimensions are made for possible carrying through doors with doorframe 800 mm.
Resistance and tightness - PP and PE are 100% resistance against aggressive grease acids, and it is possible to make grease trap from stainless steel.
Simple operation cover is equipped by fast-bind cap and construction of pipeline makes possible operation without non-hygienic handling with tubes.

Boralit grease traps are manufactured in conformity with the German DIN4040 standard and can capture all grease of vegetable or animal origin. That's why grease traps are ideal for use in kitchens, restaurants, butcher's shops, food industry, Installation can be done according to local standards and, on demand, under surveillance of our own specialists in the field. A service we can offer for all of our products.

It is based on the density difference between the particles inside the grease interceptor.
Greases, with a density of 0.95, rise to the surface while heavy matter with a density of 1.1 settle to the bottom of the interceptor.
The grease-containing water arrives in the interceptor through the inlet device (1), fitted with an anti-splash nozzle to avoid stirring up the sludge and grease that have already decanted out (2).
The partition (3) retains the sludge in the first part and the outlet siphon (4) keeps the grease inside the interceptor.

FOG HOG® fat, oil & grease interceptors combine a proven grease/water separation process with a new lightweight, noncorrosive, durable, operator-friendly interceptor design. The FOG HOG is easily installed in the commercial kitchens of restaurants, cafeterias, motels, hotels, and other institutions where food is prepared. The FOG HOG is PDI and IAPMO certified and removes more than 95% of fat, oil and grease from high-strength wastewater.

All KESSEL grease separators function using the gravity principle. Wastewater containing grease and cooking oils enters the separator through a inlet calming device so as not to interfere with the separations process. Inside the chamber, heavier sludges settle to the bottom while lighter oils and grease rise to the surface of the separator. The cleansed wastewater then exits the separator and flows into a public or private sewer system. The collected sludge and grease should be disposed of monthly by a licensed disposal company. During disposal, the entire contents of the separator are pumped into a waiting disposal truck and finally the empty grease separator is refilled with fresh water and placed back into operation.

Separators of light liquids AS-TOP are determined for catching and separating of free light liquids (mainly oil liquids) from wastewater. Separators are served for treating of wastewater from industrial production, mechanization production, lay-by and parking areas, wash-cars machines, in places, where is possibility of drip of light liquids or possibility of outflow of light liquids into aboveground water.
Inovation of separators of light liquids:
- more effective usage of sedimentation part
- new construction of coalescent filters - utilization of cylinder shape and increasing of utility value of stainless steelconstruction
- progressive construction of tank, which using technology of concreting on construction site into double-wall from plastic
- compatibility of size-line can possible individual solution of assembling of device according customers wishes

Hydrocarbon separators are developed to separate oil and petrol from wastewater. All separators can be equipped with a coalescence filter with floating carriers that help hydrocarbon particles to separate from the water. All separators come with an automatic valve installed at the outlet which makes sure no effluent can leave the separator after its maximum capacity is reached. This way, no harmful fluid can endanger the environment. If the effluent sorts into surface water, a coalescence filter guarantees the purity of the effluent that leaves the separator.

Where run-off is draining from relatively low risk areas such as car-parks and non-operational areas, a source control approach, such as permeable surfaces or infiltration trenches, may offer a suitable means of treatment, removing the need for a separator.
Oil separators are installed on surface water drainage systems to protect receiving waters from pollution by oil, which may be present due to minor leaks from vehicles and plant, from accidental spillage.
Separator Standards and Types
A British (and European) standard (BS EN 858-1 and 858-2) for the design and use of prefabricated oil separators has been adopted. New prefabricated separators should comply with the standard.
Separator Classes
The standard refers to two ‘classes’ of separator, based on performance under standard test conditions.
Class I
Designed to achieve a concentration of less than 5mg/l of oil under standard test conditions, should be used when the separator is required to remove very small oil droplets.
Class II
Designed to achieve a concentration of less than 100mg/l oil under standard test conditions and are suitable for dealing with discharges where a lower quality requirement applies (for example where the effluent passes to foul sewer).
Both classes can be produced as full retention or bypass separators. The oil concentration limits of 5 mg/l and 100 mg/l are only applicable under standard test conditions. It should not be expected that separators will comply with these limits when operating under field conditions.

The interceptors must comply with various standards with respect to both construction and dimensioning.

Mud traps can filter sand, mud, food rests, pebbles, out of wastewater. Mud traps should be installed wherever there's a risk of waste entering into the environment.

The starch interceptor also works on the decantation principle: as the various types of starch have a different density, matter decants over the whole surface.
The starch-containing water arrives in the interceptor through inlet neck (1). The effluent is immediately sprayed by nozzle (2). One characteristic of starch is that it produces foam, which has to be broken down.
The spray is triggered by a solenoid linked to the peeling machine.
