DLM/KS
Sewage sludge mixer NONFOOD

For efficient hydrolysis of sewage sludge

 

 

INDAG hydrolysis mixer DLM/KS is used for efficient hydrolysis of dewatered sewage sludge. This target is reached by full condensation of pressure steam inside of dynamical mixer. Without intensive mixing of pressure steam into sewage sludge a lot of heat quantity is lost unused. Volume of downsteam reactor can be reduced. Hydrolyzed sewage sludge will be effectively dewatered in a second dewatering stage. Dry substance (DS) content of dewatered sludge is increased. Transport costs of dewatered sewage sludge – i.e. to burn – is reduced.

 

Advantages of DLM/KS

  • No pressure loss
  • No blockage
  • Entwining (clog) free
  • Very homogeneous mixing result
  • Mixing energy can be changed variable and adapted to product or capacity changes
  • Higher DS-values of dewatered sewage sludge
  • Considerable reduction of energy cost (pressure steam)

Technology of DLM/KS

INDAG mixer type DLM/KS is equipped with flexible mixing elements on rotor. These mixing elements mix intensively and homogeneously pressure steam into sewage sludge. Rotor is supported by own bearing block. Bearing block is designed with strengthened bearings. Mixer DLM/KS is equipped with double acting mechanical seal. Mixer is designed for a maximal pressure of 18 bar and a maximal temperature of 207°C.
