The challenge
The company’s wastewater treatment plant in Belfast requires blowers to aerate the site’s sequencing batch reactors and treat wastewater. By oxygenating the activated sludge within the reactor withaeration air, the blowers help break down organic compounds within the wastewater.
Charles Brand previously used five 132 kW oversized blowers for this aeration process. These units were 16 years old and required increased maintenance to keep them in good working order. The company’s compressors suffered three failures in as many months, with each repair costing in the order of £6,000. Faced with escalating costs, Charles Brand identified that savings could be made by upgrading their aeration system using advances in blower technology.
