    Sludge drying beds and lagoons | Sludge Processing

    Jun 18, 2020 Sludge drying beds, along with lagoon technology, represent the simplest of the dewatering technologies. They are typically employed directly for stabilised, unthickened solids from extended aeration and digested solids. Drying beds are uncomplicated in design and operation, since they involve simply spreading the sludge as a thin (up to 300 mm
