Applications
  • Anaerobic digestion
    Anaerobic digestion requires temperature equalization and the proper homogenization of the biomass. Floating crusts must be broken and the formation of foam must be prevented. Sulzer can provide an ideal homogenization solution for many common digester designs.

  • Biological process
    The target of the biological process is to remove organic, biodegradable substances via the metabolism of microorganisms and related biochemical processes.

  • Chemical mixing - sludge
    Sometimes it is necessary to mix chemicals into the activated sludge before it enters the secondary sedimentation tank. For example, chemicals may be used to perform phosphorous removal on the effluent from the biological process. Many plants use chemicals to improve sludge thickening just prior to the sludge buffer tank.

  • Chemical mixing sewage
    Chemicals must sometimes be mixed into the activated sludge before it enters the secondary sedimentation tank. Whenever this done, it is important to achieve an even distribution of the chemicals. Chemicals may be added to perform the chemical removal of phosphorous on effluent from the biological process. In other circumstances, chemicals such as cationic polyelectrolytes with a high molecular weight may be added to improve the quality and settling ability of flocs formed in the activated sludge process.

  • Municipal clean water treatment
    When planning new water treatment plants or upgrading existing ones, operating costs are as important as investment costs. Sulzer’s innovative pumps, mixers and compressors combine reliable treatment performance with superior energy efficiency.

  • Paper and board machine and systems
    Sulzer’s extensive product portfolio is designed to meet the most demanding hydraulic coverage requirements and for all types of liquids, making it ideal for challenging pumping, agitation, and mixing operations in stock preparation, PM approach system, broke system, white water system, vacuum system, condensate system, and shower water system processes.

  • Pulp drying machine
    Increased hydraulic excellence for your approach, cleaning, drying machine, vacuum, broke, and white water system processes.

  • Recycled fiber line
    Energy-efficient products with low life cycle costs and a lighter environmental footprint for your pulping, screening & cleaning, flotation, washing, and bleaching processes.

  • Selector
    The purpose of the selector tank is to control and limit the growth of filamentous bacteria, and then to enhance the sedimentation ability of the sludge. Sulzer provides a number of solutions for creating optimal conditions in the selector.

  • Sludge buffer tank
    The sludge buffer tank can be used for a variety of purposes. The most common application is the blending and homogenization of highly concentrated primary, secondary or digested sludge. The solution used to mix the sludge itself, or to mix the sludge with the dosed thickening chemicals, depends on the design and volume of the sludge buffer tank. Sulzer submersible mixer types ABS XRW and RW, as well as the agitator type Scaba, can be used to provide highly efficient mixing. Positive displacement, progressing cavity transfer pumps are used for sludge feed to sludge dewatering process.

  • Tertiary treatment
    Treated wastewater may occasionally require further treatment. Local discharge rules may pose strict limits that cannot be fulfilled by even the most effective process, or a higher quality of effluent may be requested for its reuse. When tertiary treatment is needed, various levels of filtration can be applied, including very fine filtration. Often, however, a final step of mixing and aeration is sufficient to achieve the target. When this is the case, Sulzer's submersible mixer types ABS XRW and RW can be used, along with submersible aerator type ABS TA–TAK and disc diffuser system types ABS PIK, DS and Sucoflow.
