It uses hot air direct contact to dry the sludge. It has a built-in high-speed rotating crushing shaft to completely solve the sticky phase problem of sludge. The sludge with different moisture content is directly reduced to 20%, and the reduction is 80%.Medium-Temperature Belt Dryers for Biosolids,recirculated through the dryer; exhaust air flow is smaller and thus easier to deodorize; they can disinfect biosolids to generate a Class A product. To keep fuel consumption low, medium-temperature belt dryers should be preferably installed where waste heat of sufficient quantity and temperature is available, e.g. from CHP systems.Berlie-Falco - Low temperature belt dryer,The Bristol Waste Water Treatment Works in Avonmouth, UK, operates since 2008 a belt dryer evaporating approximately 3 tons of water per hour heated with steam that is heated by exhaust gases from generators. The sludge to be dried comes from an advanced anaerobic digestion and its biogas is used in the generators to make electricity.Advantages of Microwave Sludge Drying | Burch BioWave,Unlike most sludge dryers which require the material to be agitated to ensure even heating, microwave dryers agitate the microwave energy itself. Eliminating the need to agitate the material eliminates the creation of dust and the resulting safety hazards and emission issues.Municipal Sludge Drying - Industrial Sludge Dryer,,Municipal sludge relates to people living environment and health. It is necessary dry them. However, municipal sludge is high humidity and strong viscosity and easily to bond again, traditional drying machine can’t dry it completely.
