rasvalõks

Rasvalõks, commonly known as "grease trap" in English, is a plumbing device designed to intercept and retain food grease and solids before they enter a wastewater disposal system. Originating from the Estonian language, the term combines *rasva* (grease) and *lõks* (trap). These devices are primarily used in commercial kitchens, restaurants, and food processing facilities where large amounts of cooking oil and food waste are generated.

The primary function of a rasvalõks is to prevent grease buildup in sewer lines, which can lead to blockages, backups, and costly repairs. Grease traps work by slowing the flow of wastewater, allowing denser solids and grease to separate from the liquid and accumulate in a chamber. Periodic cleaning and maintenance are essential to ensure proper operation and compliance with local regulations.

In Estonia and other Nordic countries, rasvalõks installations are often mandatory in establishments serving large quantities of food. The design and capacity of these traps vary depending on the volume of grease produced, with larger facilities requiring more substantial systems. Improperly maintained grease traps can pose environmental risks, as trapped grease may eventually overflow into natural water bodies, harming aquatic ecosystems.

Modern rasvalõks systems may incorporate advanced filtration technologies, such as baffles or passive grease removal units, to enhance efficiency. While they are primarily mechanical, some newer models integrate digital monitoring to alert operators when cleaning is required. Proper installation and adherence to local plumbing codes are critical to ensure effectiveness and longevity.
