sludge drying carried out

Sludge Drying Overview - Treatment Methods and Applications It is a separated solid suspended in a liquid, typically containing major quantities of interstitial water between its solid particles. This material can be dried to cut its volume and reduce most of the moisture content of the biosolids present in the sludge

    The sludge stabilization treatment has aerobic stability and anaerobic stability. Aerobic stabilization has many advantages, but the energy consumption is very high, and it is only used when the amount of sludge is small. The anaerobic stabilization of sludge is usually carried out by a medium temperature (35 ° C) anaerobic digestion method
