    How Organic Deposits Affect Cooling Tower Operation: The Answer To Low Efficiency

    Written bySean Robbins

    The efficiency of cooling towers is always a topic of discussion and worth a deeper dive. Even a well-controlled scale or corrosion inhibitor program can be significantly affected by the presence of flourishing microorganisms. Because the interior of a cooling tower is usually moist and warm, it provides an ideal condition for microorganisms to flourish and they subsequently migrate throughout the entire cooling system.

    Enjoy Superior Disinfection

    Written byRose Lagrimas

    It’s Easy, Safe, and Simple! Many industries, especially food, beverage, and healthcare must ensure a highly efficacious program for the control of pathogens, bacteria, viruses, protozoa, fungi, and algae. Sodium hypochlorite solutions (e.g. bleach) have long been the go-to product for many disinfection applications. Chlorine dioxide, however, has many advantages over sodium hypochlorite and is…

    Lead the Wave to Groundwater Sustainability

    Written byMicheal Dodson

    Let’s consider how business operations impact groundwater. Water is essential to the processes that drive industry. It’s a precious resource that’s tightly regulated. Water is also corrosive to pipes, equipment, and vessels that contain it. After proper treatment, wastewater eventually flows back into municipal water systems, including groundwater storage.

    Texas College Learns a Valuable Lesson About the True Cost of Water Treatment

    Written byTechnical Department

    Challenges A college in Texas operates on an annual budget, and the purchasing policy is to award service contracts to the lowest bidder. One year that meant that Garratt-Callahan, the incumbent water treatment provider, lost the contract to a low-ball bid from a rival contractor. But at the college’s next yearly budget review, it was…

    Fast ROI and Savings: It’s Better to Own Than to Rent Your Chemical Handling

    Written byTechnical Department

    Challenges To limit handling and liability issues, a medical center in the Midwest required hands-free delivery of its water treatment chemicals. But this requirement limited its product options and made it “captive” to a single supplier. The hospital’s water treatment capabilities were sometimes threatened as it waited weeks for overdue chemical deliveries. Approach An ROI…

    Written byKelle Zeiher

    I. Challenges A large municipal water reclamation plant on the Central California Coast that runs 3 RO trains had to switch to a low-cost, low-actives supplier due to a city-mandated bid process. After six weeks of working with the new supplier, the water plant experienced the following: If the situation continued, it would have resulted…

    Biofilms, Bacterial Microbes & COVID-19

    Written byMicheal Dodson

    Fresh tap water teems with harmless life, but when water sits inside pipes for an extended period, even for just a few days, more sinister bacterial growth can occur. In fact, when a family leaves home for a week’s vacation, harmful bacteria can grow easily and multiply in static plumbing and water faucets, gathering inside Biofilms — toxic bacterial masses where microbes colonize together in a self-protective layer of communal slime.
