Applications
  • ABSEL water and wastewater pump selection tool
    Welcome to the Sulzer web-based pump selection tool ABSEL which allows users to select pumps for the water and wastewater industry

  • Aerobic digestion
    In aerobic digestion in wastewater treatment, microorganisms continue to break down the organic material. These microorganisms need aeration in order to function, and some level of mixing is required to keep the process efficient and reliable. The result is reduced sludge volume and the prevention of odor. Sulzer has highly suitable products such as compressors, aerators and disc diffuser systems to support the process in the aerobic digester tank.

  • Anaerobic digestion
    Anaerobic digestion requires temperature equalization and proper homogenization of the biomass to achieve a high gas production and to avoid sedimentation of organic matters. The surface crusts must be broken and prevention of foam must be managed if there are foaming tendencies. Sulzer can provide efficient and reliable Scaba agitators for digesters with high-efficiency propellers. Muffin Monster™ grinders upstream from the anaerobic digesters condition the sludge before digestion, improving the homogenization of the biomass and protecting the equipment downstream.

  • Auxiliary services
    In each desalination plant there is a number of pumps providing auxiliary services at the different stages: filter backwash, membrane flushing, membrane cleaning, etc. Due to lower head and flow requirements, typically theses auxiliary services will require end suction, single stage pumps.

  • Biodiesel
    Sulzer has develop a unique know-how based on its distillation technology to improve both clarity and purity of biodiesel. Single cut methyl esters can be used as solvents, intermediates for fatty alcohol and raw material for mono-ethanolamides.

  • Biological process
    The target of the biological process in wastewater treatment 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.

  • Equalization
    The task of mixing in the equalization process is to blend the wastewater in order to prevent sedimentation, stratification and odor formation. It may also be necessary to mix and homogenize wastewater streams that arrive from different sources. Because the water level in the equalization tanks varies significantly and can sometimes be very low, high demands are placed upon the mixers.

  • Fatty acids
    Sulzer fractional distillation is a well-established and recognized technology in the oleochemical industry to purify fatty acids mixtures to the right of fatty acid ratio(s) or to produce single cut fatty acid at the desired purity

  • Glycerin

  • Mixed liquor recirculation
    When denitrification is followed by a physically separated nitrification step, the nitrates formed during nitrification must be recirculated. The nitrates are pumped back into the denitrification step, where the anoxic process splits the nitrate molecules into nitrogen and oxygen. This frees the nitrogen into the air. This application is best served by submersible recirculation pump types ABS XRCP and RCP, the submersible mixed flow column pump type ABS AFLX and the submersible propeller pump type ABS VUPX.

  • Outlet pumping stations
    Outlet pumping stations are required when the level of the treatment plant is lower than that of the receiving water. This is especially true when discharging into a river, which can rise during heavy rain or flood periods, or into the sea, where the level varies with the tide. Outlet pumping stations may also be needed to compensate for increasing frictional losses in the outgoing pipe at high flows, for example in long sea outfall pipes.

  • 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.

  • Product water transfer
    After post treatment, product water is pumped to the storage tanks or into the water distribution networks.

  • 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.

  • Return of activated sludge
    Outlet pumping stations are required when the level of the treatment plant is lower than that of the receiving water. This is especially true when discharging into a river, which can rise during heavy rain or flood periods, or into the sea, where the level varies with the tide.

  • RO-island HPP
    This is the heart of the SWRO Desalination process, where the desalination effect takes place. The Treated sea water is fed by means of the High Pressure pumps into the RO membranes, obtaining permeate or product water and high pressure brine rejection, whose high pressure energy is recovered by selected Energy Recovery Device.

  • RO-Island HPP 2nd pass
    This is the heart of the SWRO desalination process, where the desalination effect takes place. The treated sea water is fed by means of the high pressure pumps into the RO membranes, obtaining permeate or product water and high pressure brine rejection, whose high pressure energy is recovered by selected Energy Recovery Device.

  • 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. 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 and Muffin Monster™ grinders are used for solids reduction and sludge transfer from sludge feed to sludge dewatering process.

  • Sludge handling and transfer
    Sulzer pumps, mixers, grinders and agitators are used to condition, transfer, blend and handle sludge. Our progressing cavity, positive displacement pump range, provide a near constant flow rate with suction lift capability, for handling all types of non-Newtonian sludge and cake processes, typically demanded within the wastewater treatment plant. Maintain in place features ensure any process downtime due to the change out of wear components is kept to a minimum. The Muffin Monster™ grinders protect the equipment downstream. The sludge conditioned by grinders will not clog valves, heat exchangers, digesters, centrifuges and other equipment on the sludge line.

  • Specialty esters
    Sulzer has developed a unique process based on reactive distillation technology that combines both process steps into one, enabling, for the first time, continuous productions of isopropyl-esters.

  • 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.

  • Water intake
    Raw water to be desalted, either sea water or brackish water will be taken from natural resource and pumped to pre-treatment stage. For sea water abstraction, different intake arrangements can be considered, which will define the pump type to be installed.

  • Water intake
    Water supply is vital for our daily life. To abstract the water at the source, be it the sea, river, lake or dam, water intake pumps are needed. Sulzer offers a range of pumps that are specially engineered for such applications.
