  • Total Dissolved Solids: A Matter Of More Than Just Good Taste
    Total Dissolved Solids: A Matter Of More Than Just Good Taste

    Everyone wants good-tasting water, but most water treatment plants (WTPs) are hostages to the composition of their local source water supplies. One of the components involved in taste is total dissolved solids (TDS), which can affect both the acceptability of finished water taste and its likelihood to corrode or clog pipes and fixtures. Here’s how to quantify the problem and what to do about it if it is excessive.

  • Modern Metering Adoption At Smaller Public Water Systems
    Modern Metering Adoption At Smaller Public Water Systems

    As with most things in life, there are those water utilities that have and those that don’t. According to the EPA, less than 3% of the 150,110 operational public water systems (PWS) in the U.S. serve more than 10,000 people. And those 4,500 systems serve 79% of the population. Not that being big means living trouble free. Many of these water authorities serve cities plagued by under investment over decades in their water systems. And yet with large rate-bases comes the means to spread the investment in modern technology across many households and water consumers.   

  • A More Precise Route For Chemical Feed Metering

    In water treatment applications with varying flow rates, keeping chemical dosing rates in proportion is critical for minimizing chemical costs while still achieving optimum treatment levels. A new plastic-bodied ultrasound flow meter delivers high precision at extremely low flow rates — down to 0.15 gph (10 ml/minute), about one-third of the 0.50 gph rates offered by most other chemical flow meters.

  • Harnessing Data For Better Maintenance Outcomes

    Using a calendar to determine when maintenance is needed for pumps, blowers, and other equipment no longer gets the job done. That’s because the ability to harness data to drive condition-based maintenance is now available. Understanding how your assets are performing, versus how they should be performing, is a key step towards predictive analytics. In this Water Talk interview, Manuel Parra, business development director for water and wastewater solutions with AVEVA, discusses industrial software for asset performance management that is allowing water managers use data to reduce the cost of their maintenance and extend the life of those critical assets.

    As Midwest states struggled with record spring flooding this year, the Southwest was wrestling with the opposite problem: not enough water. On May 20, 2019, federal officials and leaders from seven states signed the Colorado River Drought Contingency Plan, a sweeping new water management agreement for this arid region.

  • Using Technology To Get An Edge On Water Loss

    Water loss is a massive problem for municipalities as distribution system leaks, metering inaccuracies, and theft combine to waste an average of 30 percent, or more, of treated product. While progress is being made on the issue — also known as non-revenue water, or NRW — there is still plenty of room for improvement. In this Water Talk interview, Jeff McCracken, a director of operations and management solutions for Itron, discusses advanced technology that digs into data to help locate both the real and apparent losses facing water managers.

  • Sludge Thickeners: The Good, The Bad, And The Smelly

    Management of wastewater sludge is a core responsibility of treatment plant operators. With this responsibility comes common challenges that must be overcome.  These include controlling odors so as to have a minimal impact on the surrounding community and minimizing hauling costs for its disposal.  Getting a handle on both of these responsibilities and more can be much easier with the proper sludge-thickening equipment.

  • A Preemptive Approach To Algal Blooms In Source Water

    The dramatic rise in algal blooms, and increases in other contaminants, has left many municipalities struggling to get a handle on their source water. However, there are effective ways to manage those problems ahead of intake to stabilize the process inside of water treatment plants. In this Water Talk interview, Justin Voty, a marketing and commercialization manager with Innovative Water Care, and Jackie Schramm, a sales manager with Innovative Water Care, discuss the benefits of taking a more preemptive approach to treatment and disinfection. Innovative Water Care, formerly part of Lonza, became a standalone business unit earlier this year.

  • How Continuous Monitoring Helps Systems Grappling With Quality Issues

    As regulations become more stringent and increased demand is putting pressure on sources, traditional sampling to maintain water quality just isn’t cutting it anymore. Relying on periodic samples analyzed in a laboratory means water managers aren’t in touch with potentially large swings in the organic load and other problems flowing into their treatment plants. In this Water Talk interview, Kerim Kollu, an applications research scientist for Real Tech, discussed the emerging technology that is enabling municipalities to reliably perform continuous monitoring.

  • Calibrating Success: Improved Tools To Maintain Flowmeter Accuracy

    Water utilities with highly successful monitoring programs tend to share a common trait: they have a well-defined plan for calibration that emphasizes frequency and tracking. However, when done properly, this process is time-consuming and often leads to unnecessary labor and downtime. The good news is that advanced metering technology is available for plants to get a better handle on the instrument’s performance with significantly less effort.

  • Sludge Sampling For Polymer Selection – Critical For Project Success

    Polymers — the chemicals used in wastewater to thicken sludges and facilitate the removal of water — are critical to the operational efficiency of sludge-thickening equipment.  Unfortunately, it’s common practice at treatment facilities to order and install equipment before even considering what the ideal polymer might be for the sludge produced at the specific plant. This flawed process is time consuming, disruptive to plant operations, and can become very costly.

  • History’s Largest-Ever Algal Bloom Approaches Florida Coast

    For those in the drinking water and wastewater treatment space, the climbing temperatures in summer months can bring with them an obstacle that seems to get worse every year — harmful algal blooms.

  • Do Your Plant Instruments Play Nice With Others? The Benefits Of Integrated Technologies

  • New Trends In Mixing Technology For Water And Wastewater

    Polymers used in wastewater treatment represent one of the most expensive operating costs for municipalities. By providing an optimal environment for the activation of these polymers, plants can improve efficiency by as much as 20 percent or more. At the same time, drinking water plant managers face enormous pressure to control the disinfection residual. In this Water Talk interview, Matt Boeh, director of sales for UGSI Chemical Feed, discusses the advanced mixing technologies that can be used to improve polymer usage as well as address drinking water quality issues in distribution systems.

  • The Role Of Activated Carbon In Short-Chain PFAS Removal

    Water utilities around the country are trying to get a handle on their PFAS problem. While the presence of legacy PFAS is well known, lesser understood replacements such as short-chain PFAS are emerging as a major issue. The short-chain compounds are particularly important because they can be more difficult to remove. In this Water Talk interview, Adam Redding, technical director for drinking water solutions for Calgon Carbon, discusses the science and economics behind effective solutions for treating water for short-chain PFAS and other contaminants.

  • New Trends In Insertion Valves

    Aging infrastructure is major headache for municipalities across the country, and many will need to keep their systems working for years before funding is available for improvements. Insertion valves, which allow for tapping into a main without shutting it down, are helping water managers maintain these older systems without disrupting customers. In this Water Talk interview, Chris Vazzana, president of Hydra-Stop, discusses the newer expansion of insertion valve products to fit a growing number of main sizes as well as the addition of smart technologies into those valves.

  • Optimizing Wastewater When Expansion Isn’t An Option

    Population growth, combined with a lack of land for new clarifiers, is putting a strain on wastewater plant operators in a number of places across the country. Smaller, more efficient clarifiers can provide the solution in a cost-effective manner. The key to their performance is rooted in flow control while optimizing detention times, energy inputs, and the use of coagulants.
