1. One Water Communication: Standardizing How We Communicate Visually About Water

    I believe that we value what we know. We use scales, models and frameworks to help us understand complex matters and materials. Review the conceptual models and categorization efforts of Daniel Defoe, Charles Darwin, Anders Celsius, John Smith Elgin Marbles, Seamus Heaney, Tycho Brahe, Captain Bligh, and my favorite, Rear Admiral Francis Beaufort, author and developer of the Beaufort Wind Scale.

  2. Engineering Angle: The Future Is Here — Embracing A New Paradigm In The World Of Water

    Among the prominent advancements in improving public health and environment over the past two hundred years, collection and treatment of domestic wastewater ranks near the top.  The traditional view of wastewater treatment has been of a “linear pipeline,” whereby wastewater is collected at one end of a watershed, transported as quickly as practical to the other end, where it is treated and discharged to the nearest waterbody as a disposal byproduct. By Art Umble, Ph.D., MWH Wastewater Practice Leader for the Americas region

  3. Instrumentation In Activated Sludge: Past, Present, And Future

    After a century of operation, the activated sludge process is still being fine-tuned to meet today’s challenging treatment and efficiency targets.

  4. The Benefits Of An Integrated Watershed Approach To Nutrient Management

    How to look beyond the wastewater treatment plant for sustainable, holistic solutions to nutrient loading

  5. An Operator’s Guide To AOP

    Here are principles and operational parameters to help today’s wastewater plant operators figure out where AOP should and shouldn’t be used.

  6. Smarter Source Water: Could New Thinking Unite Industry And Environmentalists?

    AMD can be a valuable resource for the oil and gas industry and result in cleaning up thousands of streams and rivers in the nation.

  7. Waste Heat Recovery For Desalination From Steam Power Plants

    Currently, in the Kingdom of Saudi Arabia about 1.5 million barrels of oil are consumed daily to generate electricity to drive reverse osmosis desalination plants.  This represents about 15 percent of KSA’s daily oil production. 

  8. Disinfection Performance Testing Of High-Efficiency Ultraviolet Water Treatment Chamber

    This is the second in a series of three white papers describing the design and performance of the NeoTech Aqua ReFlex™ treatment chamber. The first describes in detail the theoretical basis for the very high efficiency demonstrated by the chamber. The third paper describes how this chamber design leads to some highly desirable operational advantages beyond just energy ad cost reduction. By J. R. Cooper, Ph. D. and Gwynne Cavender, NeoTech Aqua Solutions, Inc.

  9. Theoretical Operation Of High-Efficiency Ultraviolet Water Treatment Chamber

    The NeoTech Aqua ReFleX™ water purification chambers are the most efficient and compact units available today. They require an order of magnitude less energy and less than 25% of the system volume to achieve the same or better purification result as competing chambers. This is the first in a series of three white papers explaining the benefits of these systems. By J. R. Cooper, Ph.D, NeoTech Aqua Solutions, Inc.
