    Electromagnetic Meters And Ultrasonic Meters — A Comparison

    Water and wastewater professionals rely on accurate flow measurements for process operation and regulatory compliance. Selecting the best flow meter for each application is essential to obtaining accurate flow data.

  • Zero Liquid Discharge — Maximum Recovery And Why It Finally Makes Sense
    Zero Liquid Discharge — Maximum Recovery And Why It Finally Makes Sense

    Our planet continues to become increasingly more crowded.  Pollution and waste are showing irreversible impact on a global scale, and it has become necessary to come up with solutions in all industries.  It is widely known, though perhaps not publicly thought of, that the process of purifying water creates waste.  As we remove the minerals and impurities from water, we inherently condense those impurities into a smaller body of water.  This waste affects the environment in various adverse ways.  The solution lies in a concept known as Zero Liquid Discharge (ZLD).

  • Simplified Sand Removal For Power-Gen Plant Water Intakes

    Applied successfully in thousands of water and sewage treatment schemes on all continents, the PISTA® Sand Removal Chamber serves as an efficient choice for sand removal at power generation facility water intakes. In many conventional arrangements, large sedimention basins require significant space and additional chemical usage to help maintain proper settling. The PISTA® Sand Removal Chamber significantly lessens space requirements, while removing 95 percent of surface water intake particles from 300+ microns down to 100 microns. The technology is proven in more than 2,700+ Installations, including at Power Generation Plants.

  • Using Ozone In Advanced Oxidation
    Using Ozone In Advanced Oxidation

    The advanced oxidation process removes contaminants in water and wastewater by oxidation through reactions with highly reactive hydroxyl radicals (.OH). This chemical process uses ozone (O3), hydrogen peroxide (H2O2), and/or UV light.

  • Design And Care Of Reverse Osmosis Systems, Part 2: Upstream Equipment
    Design And Care Of Reverse Osmosis Systems, Part 2: Upstream Equipment

    The success of a new reverse osmosis (RO) membrane system is often directly related to its pretreatment. The previous section of this article discussed RO design issues and introduced how a pilot study should include a study of its probable pretreatment equipment since the pretreatment performance will directly affect the performance of the RO system. However, piloting the upstream processes can be challenging in sizing these components for the pilot RO unit’s low flow rate.

  • Connecticut Water Utility Successfully Removes 45% Of Trihalomethanes (THMs) With Quick-Turnaround Clearwell Intervention
    Connecticut Water Utility Successfully Removes 45% Of Trihalomethanes (THMs) With Quick-Turnaround Clearwell Intervention

    In the past several years, Aquarion Water Company had been monitoring their system’s THM formation and attempting to lower them through treatment and distribution system changes. Aquarion engineers decided that reducing THM formation in the Laurel High Service Clearwell at the Stamford Water Treatment Plant (WTP) would eliminate concerns of elevated THM formation in the distribution system served by the WTP.

  • DC Water’s Unconventional Approach To Utility Management
    DC Water’s Unconventional Approach To Utility Management

    Over the past 10 years, DC Water has become the harbinger of the modern water utility. It’s often unconventional approach to tackling age-old problems usually elicits one of two responses from other utility professionals. The first response is one of resignation — if only I had the budget that size permits, I’d be able to do similar things. And the second is one of awe — there’s no way I have the amount of gumption to convince regulators or customers that I have a better way.

    A couple of weeks ago, Environmental Protection Agency (EPA) administrator Scott Pruitt called PFAS groundwater contamination “a national priority” and pledged action at an EPA national PFAS leadership summit.

  • Effective Utility Management Starts With Data
    Effective Utility Management Starts With Data

    Over the past decade, there has been a considerable effort in the water sector to address industry shortcomings through collaboration. And perhaps there’s been no greater initiative to try to help water utility managers in their day-to-day and future planning than the Effective Utility Management (EUM) Initiative.

    Measuring pH And Its Role In Corrosion Control

    Corrosion control has always been a priority for distributing safe drinking water throughout the world’s networks of pipeline. This has become all the more critical following the outrageous lead poisoning revelations in Flint, MI — an incident caused directly by corrosion of the city’s lead-based infrastructure.

  • Affordable Sewer For Small Communities
    Affordable Sewer For Small Communities

    Affordability and maintainability are two of the greatest challenges small municipalities face when constructing and managing sewer infrastructure. With these challenges in mind, it’s important for small cities to choose wisely when investing in a wastewater system that needs to last for 30-60 years.

    Green Energy And Decentralized Water Treatment For The Caribbean

    Among water treatment industry professionals, consensus is growing that small- to medium-scale decentralized desalination and wastewater treatment plants are the way forward in a water-stressed future. But governments continue to announce new water mega-infrastructure projects at an alarming rate. Because the public policy debate appears to have simply not caught up with current technology, many companies and NGOs with a focus on small- to medium-scale water treatment or renewable energy have begun to see the Caribbean as something of a new frontier.

  • What Happens To The Chesapeake Bay Now?
    What Happens To The Chesapeake Bay Now?

    One of the great turnaround stories in the history of our nation’s water bodies is that of the Chesapeake Bay. Since 1976 when the Environmental Protection Agency (U.S. EPA) first undertook a comprehensive study of the Bay, efforts to address excessive nitrogen and phosphorous degradation of water quality have steadily improved the Bay’s complex ecosystem.

  • Wastewater Service Charges Continue To Rise
    Wastewater Service Charges Continue To Rise

    Wastewater service charges vary considerably across EPA regions and States. That’s one of the key findings from the National Association of Clean Water Agencies’ (NACWA) Cost of Clean Water Index. If you live in Montana, Wyoming or the Dakotas (EPA Region 8), your average service charge of $261 a year is considerably less than the $884 your fellow Americans up in New England (EPA Region 1) are paying.  As you can imagine, much of the difference is to do with population size and geography.

    Hydrant Humor: Tales From The Field

    District Sales Engineer Andy Singer has spent enough time troubleshooting problems in the field that not much surprises him anymore. When it comes to dry barrel fire hydrants, though, he still gets a chuckle out of some of his more outrageous experiences. Here is his educational and entertaining take on the care and maintenance of fire hydrants, and ways to maximize a utility’s return on what potentially can be a 50+-year infrastructure investment.

    How The EPA Reacts To A Government Shutdown

    Did you know that the Environmental Protection Agency (EPA) had a published Contingency Plan in anticipation of the current government shutdown? I guess in hindsight, you would have expected it for an agency with 134 facilities dotted across the country. And in fact, it’s required by the Office of Management and Budget (OMB) under Circular A-11, Section 124 that all government agencies have plans for an orderly shutdown “in the event of an absence of appropriations.”

  • The Caribbean’s Wastewater Problem
    The Caribbean’s Wastewater Problem

    For decades, wastewater management has been a growing problem for the Wider Caribbean Region (WCR), a problem that regional governments have long understood as a threat to the economy, the environment, and to public health. In the Caribbean, most wastewater from cities, industry, and agriculture pours directly into surface water or into the sea completely untreated, degrading residents’ quality of life, as well as the region’s biodiversity, pristine blue waters, and reefs, which are the lifeblood of the vital tourism industry.
