Main design features
Due to its innovative design, the small-footprint HST turbocompressor has no wearing parts nor lubricants, thus requiring minimal maintenance. The unique drive technology enables optimal operating efficiency with minimized energy consumption. It can operate either as a single compressor or as a group of compressors via a number of interface choices, enabling remote or local control of both flow and pressure over the full operating range.
Key characteristics
Air flow range 1,000–16,000 Nm³/h
Pressure range 30–120 kPa

Applications
  • Aerobic digestion
    In aerobic digestion, microorganisms continue to break down the organic material. These microorganisms need oxygen 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 to support the process in the aerobic digester tank.

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

  • 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.

  • 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.

  • 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.
