Sludge drying technology
WebbThe technology behind Drying Matter The input is wet sludge which typically contains 60-85% water. In the drying process the sludge is exposed to dry air which continuously circulate in a saturation cycle and drying cycle. This dry and slightly heated air is saturated by water vapor when in contact with the wet sludge. WebbUniversal Drying Systems brings a unique methodology using a Hybrid Paddle Drying System to resolve all these issues with efficiency and the highest quality. The game changer is the ability to transform biomass/sewage sludge disposal problems into a Class A Fertilizer! We will follow the exact same path as the Europeans:
