Modern aeration blower selection - From an energy efficiency perspective
Annual Conference
❄
Gas transfer is a vital part of a number of modern water and wastewater treatment processes. The most common application of gas transfer in the field of modern wastewater treatment processes is in the transfer of oxygen in the biological treatment – blower air aeration.
In wastewater treatment plants, the blowers are typically expected to supply a wide range of air flows with a relatively narrow pressure range under varied environmental conditions. With the increasing need for energy conservation, the design, selection of an energy efficient blower system and optimum life time cost to meet current and future demand is becoming a common challenge for the designers and owners.
This paper discusses various types of common aeration blower technologies available on the market, flow and load applications, noise treatment, operation and maintenance requirements. The advanced high speed turbo centrifugal blower technology and its associated benefits are also discussed.
