The disposal of waste cooking oil (WCO) is a major concern due to its potential impact on the environment. WCO can contaminate water and soil, and its improper disposal can harm aquatic life and the ecosystem. To address this issue, this project aims to fabricate a centrifuge to remove unwanted contaminating particles from WCO, making it clean for appropriate new use (e.g. as feedstock for biodiesel production). The project also aims to demonstrate the feasibility of fabricating a centrifuge without the need for a large initial investment and to contribute to the circular economy by reusing materials.
The centrifuge consists of a 4.1kW three-phase electric motor, a transmission system, a bowl rotating, and an oil circuit. A variable frequency drive regulates the speed of the motor to rotate the bowl at a speed of 3000 rpm. An oil pump with a power of 550 W drives the WCO from a tank to the bowl, and the flow rate is regulated by a manual valve. The total cost of the project was 750.04€, a cheap price due to the reuse of most of the components and materials.
The centrifuge was tested, and a visual test showed significant differences in colour and opacity between the WCO and the cleaned WCO. However, some marginal failures were observed during the operation of the centrifuge, and improvements can be implemented in the future to address these issues.
In conclusion, this project demonstrates the potential of separation technologies to contribute to sustainable engineering and provides a valuable contribution to the field.
