Welcome to the November/December edition of Industrial WaterWorld magazine. This month, our feature topic focuses on the electric power industry where some fascinating research is taking place at the Water Research Center (WRC) at Georgia Power’s Plant Bowen. As Jeff Gunderson explains (here), the WRC is a collaborative initiative amongst seventeen organizations, including the Electric Power Research Institute, Southern Research, and Georgia Power. Its mission is to develop and test technologies to reduce power plant water consumption and improve the quality of water returned to the environment.

Here, author Holly Neuhaus discusses the link between cooling systems and waterborne diseases, particularly Legionnaires’ disease. She outlines how a new standard, ANSI/ASHRAE 188, aims to mitigate the presence (and ultimately the spread) of waterborne bacteria by ensuring that building owners and managers implement a risk management plan for the water systems in their buildings.

Our third feature (here) offers an in-depth look at electrodeionization (EDI) technology and how it has come a long way since it was first introduced nearly 30 years ago. Back then, drawbacks to the technology, such as the formation of scale in the stacks and other operational challenges, stunted its growth. But, as authors Erik Hanson and Tom Kosir explain, technical advances have not only addressed earlier deficiencies but have elevated EDI to become one of the leading technologies for the production of ultrapure water.

Hexavalent chromium and cyanide - two difficult-to-treat compounds that are the bane of many a wastewater treatment professional’s existence. In our case study here, learn how one of the largest precision plating shops in North America met its challenge with an innovative filtration system capable of handling a mixed wastewater stream that could ultimately be reused throughout the factory in a zero-liquid-discharge regime.

And finally, be sure to check out this month’s Market Innovation column here, which highlights a two-for-one process that combines eco-friendly wastewater disinfection with renewable energy generation. The patented wastewater treatment system recycles heat over and over as it disinfects wastewater, making it extremely energy efficient.

We hope you enjoy this edition of Industrial WaterWorld!
