Wastewater treatment facilities commonly use low-pressure multi-stage blower/compressors to supply air to aeration tanks where mixing and biological oxidation is promoted. These throttle controlled multistage blower/compressors are notoriously inefficient, may require independent cooling, and a great deal of maintenance while offering poor control, loud noise, and a large physical footprint.
Alternatively, there is a technology of a completely different design from these existing compressors. This centrifugal High-Volume, Low-Pressure (HVLP) turbo compressor uses precision
machined components and integrated variable frequency drive
controls that allow it to match the existing system flow and
pressure requirements while using substantially less electricity.
Although the cost for this new technology is higher than
purchasing a replacement multistage compressor (or upgrading
the existing compressor with a variable speed drive), kWh usage
is dramatically reduced. Most importantly, after replacing the
two operating compressors, the sustained energy savings
combined with the one-time PG&E incentive resulted in a project
payback of just over two years.*
OTHER HVLP COMPRESSOR USES
This HVLP compressor technology can
be used in multiple other industries and
processes including:
- Air knife applications
- Oil free air supplies
- Flue gas, oxidation air
- Pneumatic conveying of powder,
flour, chemical gas
- Pulp and paper industry
- Drying, processing, packaging
- Fermentation
- Many other custom processes
