In the past few years, heating, ventilating and air conditioning (HVAC) services have shown considerable growth in the field of remote diagnostics and fault detection.

In the past decade, microprocessor controller technology has advanced to provide optimum functionality, improved microprocessor capacity and more sophisticated software algorithms—all at a reduced

To manage data from remote systems such as pump stations, overflow tanks or wells, most water treatment systems rely on a supervisory control and data acquisition (SCADA) system.

In complex systems, many factors can affect overall performance.

My previous two columns have described assessing a system that does not use controls. In the first part (Pumps & Systems, October 2014) the assessment process was detailed.

In Texas, the hot, dry summers make water use and conservation a top priority.

Power generation plants face difficulty when conserving water, regardless of size or fuel source.

With easy access to electricity, electric motors are now an option for large pumps and compressors once powered by gas engines or turbines.

Who determines where pressure gauges are located in a pump system? How close to the pump should they be, and what happens if these rules are not followed?

Approximately 75,000 gallons of water are required to produce 1 ton of steel. Water transfers heat, removes scale from steel and converts gases produced in ovens and furnaces.

For those of you old enough to remember Lawrence Welk, you’ll notice that the title of this brief column is the final quote from his show’s closing song. I am still a loyal fan of his reruns today.

Despite its name, pump specific speed (NS) does not have much to do with the actual speed of a pump.

A reciprocating power pump, as depicted in Figure 1, is a displacement machine. It has characteristics that are different than a centrifugal pump.

Today marks the final day of the 2015 International Water Summit (IWS), a gathering of water and sustainability experts from around the globe. Thousands gathered in Abu Dhabi this week to discover solutions to problems such as water scarcity and efficiency.

Previous “Pump System Improvement” columns covered the assessment of simple systems with a single load. The system discussed in this column has multiple loads. Figure 1 is a schematic of a piping system under evaluation.
