A new turbocompressor reduces costs and boosts reliability for smaller treatment works
Sulzer’s range of HST turbocompressors offers energy efficiency and reliability M
unicipal and industrial wastewater treatment plants require aeration to remove organic
contaminants. Traditionally, noisy blowers have been at the heart of this process, as well as the source of significant operational costs. With the launch of Sulzer’s HST 10, smaller sewage plants processing less than 10,000m3
/day (40,000
population equivalent) can take advantage of the benefits of a turbocompressor that will both cut running costs for their facility and provide a huge boost in reliability, according to the company. In industries such as pulp
and paper, food and beverage, chemicals, pharmaceuticals and mining, the HST 10 can provide productivity improvements in both core processes and integrated wastewater treatment facilities.

BOOSTING EFFICIENCY AND RELIABILITY The HST 10 is a single stage turbocompressor and motor directly coupled to the turbo with no intermediate gears or pulleys. The permanent magnet motor is fed by the integrated variable frequency converter. To reach the high rotational speeds needed with minimum losses, active magnetic bearings are used and the motor and the whole unit are fully air cooled. There are no gears, mechanical
bearings, pumps or separate cabinet cooling fans and the absence of these often failure-prone components makes the system more reliable than traditional blowers, according to the company. Combined, the lower energy costs and running expenses offered by the machine are likely to lead to a reduction in operational expenditure (OPEX).
REDUCING COSTS In the municipal wastewater treatment environment, traditional blowers are the single largest consumer of energy on the site. Their reliability, or lack of it, can lead to considerable downtime for the aeration process, posing a risk to treatment outflow and the environment. Even with spare assets on standby, the blower house is often a cause for costly and extensive maintenance work. However, tradition has given
way to innovation, and the HST turbocompressor has made it possible to have a reliable compressor that doesn’t need constant attention or high energy requirements. Essentially vibration-free and with low noise options available, the HST 10 can be installed in simple structures such as converted freight containers. In addition, the product is compact and easy to install according to the company.
