Oil and petrol separators are used to separate oil, petrol and solid particles from waste water. Oil and petrol separators minimize the supply of mineral oils in sewers and purification facilities. Oil and petrol separators are established i.a. at service stations, mechanics, oil repositories, and carwashes.
The separation is based on the gravity principle and the different properties of solubility for water, oil, and petrol. Due to the insolubility of oil and petrol in water, oil and petrol will stay on top of the waste water in the separator, after which the oil and petrol phase can be disposed. Oil and petrol separators protect the environment from contamination of waste water.
Contaminated waste water is led into the chamber of the separator. Inside the separator, the velocity of waste water is slowed down, allowing oil and petrol to rise to the water surface and heavy particles to sink. The separated sewage water will be led through the outlet to the sewage system.
Tunetanken oil- and petrol separators are produced in fiber-reinforced composite, which is a material with low density that makes it easy to establish the separator. The material is very robust, tear-free as well as chemical and corrosion resistant.
