rasvajärjestelmien

Renväjärjestelmät, also known as grease trap systems or grease interceptors, are plumbing devices designed to prevent cooking grease, fats, and oils from entering the sanitary sewer system. They are commonly installed in restaurants, commercial kitchens, food processing facilities, and any establishment that prepares food using significant amounts of grease. The primary function of a renväjärjestelmä is to separate and collect FOG (fats, oils, and grease) from wastewater before it can solidify and cause blockages in pipes.

The process typically involves a multi-compartment tank. Wastewater enters the first compartment, where it cools. As the water cools, the FOG, which is less dense than water, rises to the surface and solidifies. Solid food particles, being denser, sink to the bottom. The relatively FOG-free water then flows into a second compartment, where further separation occurs, and then exits the system into the sewer. This process significantly reduces the amount of FOG discharged into the municipal sewer lines, preventing costly and environmentally damaging blockages.

Regular maintenance is crucial for renväjärjestelmät to function effectively. This involves periodic pumping out of the accumulated FOG and solids by a licensed waste hauler. The frequency of pumping depends on the size of the trap, the volume of wastewater, and the type of food preparation. Failure to maintain the system can lead to backups, odor problems, and potential fines from local authorities. Many municipalities have regulations mandating the use and maintenance of these systems for food service establishments.
