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.
Rural wastewater utilities rarely, if ever, consider upgrading to an automated control system.
In today’s industrial facilities, using reliability-centered maintenance as the primary approach to reduce maintenance costs and operational downtime is more commonplace.
Most engineers would say that the International Society of Automation (ISA) 100 standard covers wireless instrumentation in process plants.
Deep lake water cooling (DLWC) is a groundbreaking cooling system that provides an alternative to conventional air conditioning.
Hillview Water Company in Oakhurst, Calif., credits its cellular SCADA system for averting disaster in winter 2011.
A hydraulic pump directly coupled with a servomotor is an energy-efficient solution that delivers highly dynamic performance with double-digit energy savings typical.
Manually managing a water system can be difficult, especially with population growth and limited resources. Saving time and money are common challenges for utilities.
