  • Water Quality Comes Under The Consumer Microscope
    Water Quality Comes Under The Consumer Microscope

    Water quality is getting a lot more scrutiny these days. And that’s a good thing says Russ Swerdfeger, Global Director of Memcor Product Management with Evoqua. Alongside his colleague Daryl Weatherup, Director of Marketing with Evoqua, Swerdfeger recently discussed the future of drinking water and the key issues and concerns facing the water industry right now with Water Talk.

  • Water Concerns Unite Polarized Voters
    Water Concerns Unite Polarized Voters

    In a nation of red states and blue states, water policy is an issue that often dissolves party lines.

  • Maximum Ozone Transfer Efficiency Across Broad Range Of Water Flow
    Maximum Ozone Transfer Efficiency Across Broad Range Of Water Flow

    The design team for the intermediate ozone system at Buckingham Water Treatment Plant, Quebec, had limited space available for ozone contacting for the plant’s 1.3 – 7.4 MGD flow, so a standard fine bubble diffusion basin for ozone disinfection was not an option.

  • The Case for Trans-Basin Water Pipelines
    The Case for Trans-Basin Water Pipelines

    Those in the water industry know water is essential for life and brings economic value, but the economic role of water is often not as well understood by the general public. This paper reviews the history and development of our transportation, electrical, and energy infrastructure and then presents a plan for our nation’s water to be augmented from where we have it abundantly to where we badly need it.

  • Protecting Pressure Sewer Investments With Longer Pump Warranties
    Protecting Pressure Sewer Investments With Longer Pump Warranties

    More long-term data is available than ever before to help wastewater designers and engineers make accurate estimates of up-front costs and life-cycle costs associated with pressure sewer systems. In addition, incorporating extended equipment warranties into project evaluations, specifications, and contract documents is a pivotal tool to help decision makers reveal the true, long-term equipment costs of various sewer system technologies.

  • Is Iron In Drinking Water A Public Health Risk?
    Is Iron In Drinking Water A Public Health Risk?

    It’s long been thought that the presence of iron in drinking water is a cosmetic problem rather than a public health concern. But some scientists are now saying that while the iron itself might not be hazardous to your health, what it does to your drinking water is.

  • Improving The Quality Of Secondary Wastewater For Indirect Potable Reuse—From Pilot To Full Scale Plant
    Improving The Quality Of Secondary Wastewater For Indirect Potable Reuse—From Pilot To Full Scale Plant

    In spite of the recent abundance of water, many of California’s aquifers continue to balance on the edge of water scarcity. Decades of overpumping have reduced the amount of ground water available to supplement surface water resources diminished by drought. The Pure Water Monterey Ground Water Replenishment Project (Monterey Pure), addressed the need to replenish a local aquifer, by piloting Advanced Water Treatment (AWT) processes, to determine the best method to convert secondary wastewater into a pure water resource.

  • Making Municipal Water Supply Reliable, Economical, And Sustainable
    Making Municipal Water Supply Reliable, Economical, And Sustainable

    A global scarcity of resources is a compelling reason for businesses and people to use raw materials more responsibly. Modern municipal water supply concepts must therefore not only consider such aspects as the structural development of the region and the population’s quality of life, but must also integrate the sustainable use of water in their policy planning.

  • World Water Day Redux
    World Water Day Redux

    It has been five years since I first published this post on World Water Day to remind the general public on how they can play a role in conserving one of our world's most precious resources. It is as relevant now as it was then.

  • Carbon Adsorption & Reactivation
    Carbon Adsorption & Reactivation

    Chemical, petrochemical, and oil-refining plants are process-intensive operations with regulatory requirements to protect the surrounding water and air from the effects of industrial pollution. These external demands are matched by equally compelling internal pressures to address product purification needs, find alternatives to utilizing costly fresh water in production processes, reduce the carbon footprint, and operate efficiently and profitably.

    ORP Sensors – Are They Really The Best Thing “Since Sliced Bread”?

    There have been many publications lately that claim universal appeal of the ORP sensors and their applicability across the board. This concerns me, because the authors sometimes forget to mention some well-known practical limitations of the method, let alone the realities of water treatment applications potentially influencing the sensor performance.

    Lessons Learned From Flint

    We all hope that the Flint Water Crisis – where cost-cutting measures led to the drinking water supply to become severely tainted with lead – was an isolated incident. However, it is not impossible that a similar event could happen again, especially in a similarly  desperate city with limited financial resources. Here are a few key points that should be considered to avoid repeating such a tragedy.

    Power Plant Water: Wanted Dead And Alive

    Water is the lifeblood of electrical power plants, whether they are water-cooled steam plants or turbine-spinning hydroelectric installations. Regardless of how the facility generates electricity, there is a growing awareness that each power plant is part of its own, unique industrial watershed — drawing water from the environment, altering its contents and temperature, releasing some to the atmosphere as steam, and returning the rest to receiving waters.
