AZ Utility Breaks New Ground In Water Reuse Using SCADA By Christopher Little, Trihedral Engineering Limited
The Fountain Hills Sanitary District, which provides wastewater treatment for more than 13,000 homes and businesses, developed an innovative way to make up for the shortfall during the drier, less-populated summer. The process, known as aquifer storage and recovery (ASR), involves injecting excess treated water into the aquifer and recovering it when summer demand increases.
Evaluating Different Blower Technologies On A Wire-To-Air Basis By Andrew Balberg, Atlas Copco Airpower Compressor Technique
Blower manufacturers and their related industries are researching ways to develop fair evaluation criteria and specifications that can be used to determine which blower technology offers the best energy efficiency and performance for a particular application. The evaluation would measure the total energy consumption used by the entire blower system in real-world conditions while taking into account all potential energy losses.
UV Installation Proves All Lamps Are Not Created Equal By WEDECO -- A Xylem Brand
Summerville, GA, a small city in the northwestern part of the state, built their two MGD wastewater treatment plant in 1967. It was designed to handle the flow from a developing municipal collection system that now serves 1,860 connections. During an upgrade, lower-priced, aftermarket lamps were purchased and installed in the UV system. They failed to meet expectations within eight months.
Leak Detection Using Conductivity By Emerson Process Management, Rosemount Analytical
The basic principle behind leak detection using conductivity is measuring and alarming the change in conductivity in a sample brought about by a leak into it by a contaminant. The contaminant either increases or decreases the conductivity of the sample depending upon its solubility with the process solution.
Kevin Marsh, of Hach, explains how the latest advancements in mobile technology allow customers to measure data, such as speed and depth of sewage flow from a remote location, allowing for increased insight and reduced capital expenses.
HPD evaporation and crystallization systems drive efficiency and innovation toward zero liquid discharge (ZLD) for power generation, oil and gas, chemical processing, and landfill leachate applications.
