Sludge is a byproduct of sewage treatment. Improper treatment can have a negative impact on the environment and health. The following are some common methods for sludge treatment:

  1. Pretreatment: Improve the physical and chemical properties of sludge through chemical treatment, thermal treatment, biological treatment and other means to improve the efficiency of subsequent treatment.

  2. Concentration: Increase the solid content of sludge through gravity, flotation, centrifugation and other methods.

  3. Dehydration: Use belt filter press, plate and frame filter press, centrifuge and other machines to remove moisture from sludge.

  4. Drying: Use industrial sludge dryer to further reduce the moisture content of sludge and improve the calorific value and stability of sludge.

  5. Incineration: Send the sludge to the incinerator to completely inactivate pathogens and reduce the volume of sludge.

  Industrial sludge dryer is specially designed for sludge with high moisture, high viscosity and low calorific value, and plays an important role in sludge treatment. The commonly used sludge dryer is a drum-type structure with a built-in lifting plate to break up the sludge, increase the heating area, and continuously exchange heat between the sludge and the hot air to achieve the purpose of drying. The industrial sludge dryer has mature technology, high degree of automation, simple operation and convenient maintenance. It is suitable for various types of sludge with different moisture contents, and has a complete tail gas treatment system. It is an environmentally friendly dryer equipment.

  Applications of industrial sludge dryer

  Wastewater treatment plant: used for further drying of sludge after dehydration to increase the calorific value of sludge.

  Industrial sludge treatment: suitable for industrial sludge with high water content and high viscosity.

  Agricultural sludge treatment: used for sludge resource utilization, such as fertilizer making, brick making, etc.

  Industrial sludge dryer plays a key role in sludge treatment and is an important equipment for increasing the calorific value of sludge and realizing resource utilization.
