Sewage sludge utilisation at a mega plant in Bello, Colombia
Located in the second largest Colombian city of Medellin, the new Bello wastewater treatment plant for 2.75 million PE and a maximum inflow of 6.5 m³/s went into operation in 2018. For drying of the resulting sewage sludge, HUBER SE installed several lines of its proven belt dryer, thus realising an international mega-project with one of the largest sewage sludge treatment plants worldwide.
Three HUBER Belt Dryer BT 30 units dry the 400 t dewatered sewage sludge per day from an average of 28% DR to over 90% DR. Furthermore, HUBER supplied the sludge bunkers, conveyor technology, vapour condensation, cooling towers, exhaust air treatment and the control system for the drying plant.
The sewage sludge treatment concept implemented here is not only groundbreaking for the whole of Latin America. The latest coordinated technologies, fully automated control systems and process control technology are implemented in this project. The use of highly efficient drying technology in combined heat and power generation can also be applied economically in Europe. The flexible heat utilisation concept of the HUBER Belt Dryer BT allows the utilisation of various waste heat sources and offers a suitable, tailor-made solution for any application.
Detailed case study
HUBER Belt Dryer BT 30 in Colombia
Located in the second largest Colombian city of Medellin, the new Bello wastewater treatment plant (2.75 million population equivalents) with a maximum inflow of 6.5 m³/s went already into operation in mid-2018. For drying the sewage sludge treated in the 6 digesters, the HUBER Schrader-Camargo consortium installed the proven HUBER Belt Dryer BT, thus implementing an international mega project. The contract value for the consortium for the construction of the turnkey drying plant is over 44 million Euros.
