Integrated Technology Simplifies Dewatering Process at Two Municipal STPs   Water & Wastes Digest October 2002
In the late 1990s, one western Pennsylvania sewage treatment plant (STP) sought to process Class B biosolids on-site, eliminating the expense of hauling liquid off-site and significantly decreasing associated labor costs. At the same time, the plant needed to achieve higher cake solids and provide strict odor control. In addition, the selected equipment also had to be able to greatly enhance process efficiencies at not just the one plant, but its sister facility as well. Fortunately, USFilter offered a fairly simple solution to meet the STP's seemingly complex needs.

Data Acquisition, Legacy Systems and Your Intranet   Water & Wastes Digest February 2001   By Fred Noble
There are lots of parallels between the events of November 2000 and the events that take place in any factory or municipality that runs a process or monitors its effluent. The technology exists to achieve the much-talked-about six sigma (3.4 errors per million events) levels of measurement quality or process integrity. But antiquated legacy systems keep getting in the way. And, as is the case on the American political scene, it just is not that easy to replace those old methods of measuring things.
