One of the most misunderstood aspects of the water and wastewater industry is the presence of
air in a pipeline and its impact on operations. Many operational problems, especially at the time
of initial start-up, including damaged equipment, as well as faulty instrumentation readings, are
blamed on inadequate thrust blocking, improper pipeline bedding, etc. But in reality, many of
these problems are not caused by improper installation of the line, but by failure to de-aerate the
line. Properly de-aerating the pipeline will safeguard it from air-related problems.
