Rasvalõksud

Rasvalõksud, also known as grease traps or fat traps, are plumbing devices designed to intercept and retain FOG (fats, oils, and grease) from wastewater. They are commonly installed in commercial kitchens and food processing facilities to prevent these substances from entering the sewage system. FOG can solidify in pipes, leading to blockages, reduced sewage flow, and potential environmental damage if it reaches waterways.

A typical rasvalõks consists of a tank that receives wastewater from kitchen sinks, dishwashers, and other food preparation equipment. Inside the tank, the wastewater cools, causing the lighter FOG to separate and float to the surface, while heavier food solids settle to the bottom. Clearer water is then discharged from the outlet of the trap. The design allows for the FOG and solids to be easily removed during regular maintenance.

Proper functioning of a rasvalõks is crucial for maintaining the integrity of public sewer systems and preventing costly repairs. Regular cleaning and maintenance are essential, as an overloaded trap can become ineffective, allowing FOG to escape. Local regulations often mandate the installation and maintenance of rasvalõksud in establishments that produce significant amounts of FOG. The accumulation of FOG can create unpleasant odors and can also be a breeding ground for bacteria.
