A device that is steadily growing in popularity is the automatic grease trap. It is a mechanical grease trap consisting of a plastic or stainless-steel waterproof tank with a system of scum-boards and partitions, supplemented with a system that is capable of automatic or semi-automatic cleaning. It means that sludge can be removed without directly opening the trap. Everything can work simply on the basis of the connection of a suction vehicle to a quick-connection coupling, which is installed on the external façade of the building. Therefore, this system is mainly used in places where the opening of the trap may cause hygienic problems, i.e., in restaurants, fast-food shops, kitchen facilities, and meat and meat product processing plants.

In the case of increased requirements for outflow parameters, the use of a combination of traps with biological cleaning, coagulation, flotation, or electro-flotation can be considered. In such cases you should take into account whether the effect expressed by capturing several grams of grease a year will be worth a considerable increase in operating costs. Reducing the concentration of non-polar extractable substances will pay off in the case of major producers, where the production of wastewater steeply increases and thus the final balance of pollution as well. In such cases, using a new technology, the SFT filter, is appropriate, but we will talk about that later.
