Rotary Kiln

The sludge drying process is a thermal treatment that removes water from wastewater sludge via evaporation. Applying heat reduces moisture content from a typical 75-85% to just 5-15%, achieving a 75-90% volume reduction. This transforms heavy, wet waste into a dry, stable, and, if required, pathogen-free product. Industrial and municipal facilities generate millions of tons of sludge annually, creating a significant disposal challenge. The primary problem is cost: wet sludge
