Sludge thermal drying
WebbChina's total dry sludge output was 6.25 million tons. Canada and the United States produce approximately annually[4]. Due to the large volumes of sludge, the focus has shifted towards reduction, stabilization, harmlessness, and resource utilization of sludge. The thermal drying is an essential intermediate stage for sludge management. WebbThe low temperature nature of the thermal sludge dryer enables the BioCon™ dryer to utilize various thermal energy sources including thermal oil, air, or steam. Thermal efficiency can be further increased by employing BioCon™ Energy Exchange System. Fuel sources for the Biocon system include natural gas, biogas, or fuel oil.
