Sludge drying Lenntech

Sludge drying procedures are based particularly on contact-, convection or radiation procedures. Large amounts of air are not necessary during the contact drying, because the warmth is supplied by the contact between the damp product and a heated wall. Only a minimum gas flow is often planned for the evacuation of steam.

Sludge Drying Lagoons a Potential Significant Methane

Sludge-drying lagoons are a preferred sludge treatment and drying method in tropical and subtropical areas due to the low construction and operational costs. However, this method may be a potential significant source of methane (CH4) because some of the organic matter would be microbially metabolized under anaerobic conditions in the lagoon.
