The team of Sofiyska Voda, operated by Veolia, carried out the first of its kind preventive maintenance on a bioreactor for organic waste processing from the food industry in Bulgaria. The service maintenance of the production line optimizes the efficiency and extends the service life of the bioreactor, as at the same time the activities need to be performed without any risk for the environment.

The facility plays a key role for the environment of the capital. Organic waste from the food industry and the agricultural sector is processed in it. There that waste is utilized by specialized processing. It includes a digestion process, as a result of which two new useful resources are obtained. The decomposed mass is turned into a residual product that is harmless to nature, in which organic matter is present that can be used as a compost for fertilization in agriculture. During digestion biogas is released as well that is used as a source of energy.

The bioreactor has a large working volume – 3,600 m³. For the purpose of carrying out the maintenance, the team of Sofiyska Voda was forced to install specially designed valves - compatible with the specialized mobile equipment used for vacuum suction and transportation of the bioreactor’s contents. In addition, in order to scoop out the solid residue mass, another valve was developed and installed to ensure the controlled and safe release of wastewater.

Thanks to its skills and expertise, the company implements innovative and sustainable solutions that contribute to the realization of the ecological transformation - a strategic goal of Sofiyska Voda, operated by Veolia.
