Submersible aerator type ABS XTA XTAK

All in one aerator

The XTA and XTAK are self-aspirating submersible aerators for wastewater and water treatment in municipal and industrial plants. The main areas of application are mixing and equalization tanks, activated sludge tanks, SBR, and sludge storage tanks.

Submersible aerator type ABS XTA for wastewater and water treatment in municipal and industrial plants
Main benefits
  • Easy to install and freestanding on the bottom of the basin—no need to empty the basin for installation
  • Wear-resistant and long lifetime
  • Very low noise level, no aerosol formation, and no sedimentation on the bottom, thereby minimizing environmental effects 
  • Self-cleaning
  • High Standard Oxygen Transfer Rate (SOTR) and Standard Aeration Efficiency (SAE) values
  • Excellent solids suspension capability
Main applications
  • Activated sludge basins and Sequencing Batch Reactors (SBR), providing aeration and mixing in one unit for degradation of biomass load
  • Mixing and equalization basins providing uniform wastewater loading to downstream processes, and eliminating odors
  • Sludge storage and stabilization, providing odor control as well as oxidation of sludge
  • Flotation of oil and grease
  • Additional aeration
  • Neutralization of alkaline wastewater with CO2 or flue gas
Main design features

The XTA/XTAK self-aspirating aerator is a submerged aerator, mixer, blower, and pump combined in a single unit. It has the power to meet the most demanding oxygen transfer and mixing requirements.

The XTA aerator is available in a full range of Premium Efficiency IE3 motors from 3 to 75 kW and with an oxygen transfer of up to 80 kg O2/h.

The main areas of application are mixing and equalization tanks, activated sludge tanks, SBR, and sludge storage tanks at water depths from 2 to 9 m (7–30 ft).

Key characteristics
Oxygen transfer up to 80kg O2/h (176 lbs O2/h)
Motor range 3–75 kW (100 hp)

Applications
  • Wastewater treatment process - aerobic digestion
    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.
  • Wastewater treatment process - biological process
    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.
  • Wastewater treatment process - equalization
    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.
  • HST high speed turbocompressor
    Industrial water and effluent treatment
    Sulzer has a deep knowledge in wastewater treatment, and with our wide product portfolio we can now offer energy-efficient and reliable solutions for your water collection, neutralization, flocculation, sedimentation, cooling, aeration, sludge storage, digestion, and dewatering processes.
  • Wastewater treatment process - tertiary treatment
    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.
