Rasvapüüdurid

Rasvapüüdurid, also known as grease traps or fat interceptors, are plumbing devices installed in the drainage system of commercial kitchens and food service establishments. Their primary function is to intercept and remove fats, oils, and grease (FOG) from wastewater before it enters the municipal sewer system. This prevents the FOG from solidifying in the pipes, which can cause blockages, backups, and significant damage to the sewer infrastructure.

The operation of a typical rasvapüüdur relies on the principle of gravity separation. Wastewater from sinks, dishwashers, and other kitchen equipment flows into the trap. Inside the unit, the flow rate is slowed, allowing the lighter FOG to rise to the surface and solidify, while heavier food particles settle to the bottom as sludge. The relatively clear water then exits the trap and continues to the sewer.

Regular maintenance is crucial for the effective operation of a rasvapüüdur. This involves periodic pumping out of the accumulated FOG and sludge by a professional service. Local regulations often mandate the installation and maintenance of these devices for food-related businesses to protect public health and the environment. Failure to properly maintain a rasvapüüdur can lead to unpleasant odors, pest infestations, and costly plumbing repairs.
