DCS Versus PLC: A User's Guide To Selecting The Most Effective Control Platform For Your Application By Jim Hazelwood and Bill Butler, Revere Control Systems
Distributed control systems (DCS) and programmable logic controllers (PLC) are not mutually exclusive technologies. When the end-use application serves as the basis for making a sound decision, the selection process becomes more efficient, and a more effective outcome results. This white paper provides general guidelines and highlights key considerations when choosing a control system platform.
4 Keys To Valve Optimization And Pressure Zone Management By Brad Clarke, Singer Valve
For basic pressure management or more advanced modulating pressure management, water suppliers create a network of district metered areas (DMAs) or smaller, more manageable, pressure zones. The DMA or pressure zone gives the ability to measure flow and control pressure, when a pressure reducing valve (PRV) or automatic control valve (ACV) is installed at the takeoff of the DMA from the main distribution line. Here are the top four valve considerations for optimizing the functionality and performance of the DMA.
Cost-Effective Sour Water Stripping By Hach Company
Refineries are challenged to properly reuse or dispose of sour water by removing ammonia (NH3) and hydrogen sulfide (H2S) from water through a process called stripping.
Rainwater For Reuse As Drinking Water By UV Pure Technologies
When McMaster University in Hamilton, Ontario, built their new Engineering Technology Building they used the latest state-of-the-art technology not only to achieve LEED Gold certification, but also to create a living laboratory to train students on the building systems of the future.
Bay Best Practices: What's Working To Clean Up The Chesapeake By Jeff Moeller and Stephanie Costello of the Water Environment Research Foundation
The Water Environment Research Foundation, with support from the National Fish and Wildlife Foundation, is making it easier to sort through the options with the release of a report detailing how various techniques to control runoff in the region are stacking up. Find out how.
Stricter environmental regulations and rising energy costs are forcing wastewater treatment plants to ensure wastewater discharge compliance, and at the same time make operations more energy efficient. One of the main areas for environmental and cost savings lies just below the surface of your biological tanks.
