Today, we complete our series on selecting the right blower technology for industrial wastewater treatment applications with a guide to evaluating technologies during the blower system design process. You can read the previous articles from the series by choosing “wastewater” under industries or by following the link.
The most important factors when selecting a blower are reliability, efficiency, maintenance and capital cost. Table 1, below, is a guide to evaluating each technology based on the four key factors listed above. Although some operators may value one factor over another, in general, the blower with the lowest overall score will have the lowest life cycle cost.
It is important to remember that there is no “coverall” technology for wastewater treatment blowers. Each blower has advantages and disadvantages and should be selected based on the organization’s preference in regard to these four factors. To learn more about the following technologies, read our previous articles on positive displacement blowers and centrifugal blowers.
Table 2, below, lists each secondary wastewater treatment application, its air requirements and the recommended blower technologies for that application.
Consult Blower Test Certificates before Purchase
Several regulatory bodies govern the compressed air industry, the most reliable of which are ISO, CAGI and ASME. It is prudent to purchase a blower from a manufacturer that is ISO 9001 certified for quality assurance. Also, be sure to request blower test certificates for the following categories:
These test procedures will ensure that the blowers produce the correct amount of air while using the advertised amount of power.
