District Energy Water Treatment

District energy is a resourceful way to heat and cool local buildings centrally. That said, the efficiency gains depend on properly setting up and maintaining water treatment systems. Let Chemstar WATER’s team of experts maximize your building’s water treatment to optimize output while reducing your dependence on energy and water. Our proven solutions can save you time, labor, expenses, and maintenance costs.

Common Water Treatment Challenges District Energy Facilities Face

Water treatment systems are subject to many ongoing factors that can ultimately undermine performance or create premature replacement or repair. At Chemstar WATER, our plans are based on solutions to prevent and mitigate these common issues:

  • Sealing Building’s Closed-Loop System: ideally, the water inside your system needs to remain free of oxygen and carbon dioxide to avoid corrosion. We do this by properly sealing your system from the atmosphere to avoid harmful pipe breakdown or bacteria build-up.
  • Feedwater treatment: Even the best systems experience some water loss due to valves, seal leakages, and general flow. When this occurs, we must add make-up water to restore system pressure.  However, this water may have a different pH, so Chemstar WATER provides additional treatment to ensure that the feedwater matches the optimal requirements when entering the system. 
  • Neutralization: feedwater may contain hardness agents and harmful gasses; our treatment will help neutralize them so they do not deteriorate your system. 
  • Seasonal Treatment: with each system comes new external temperature demands on your system. In summer, many plants go idle, leading to dangerous bacteria and microbiological growth if left untreated. That’s why we recommend a routine maintenance plan of at least 2x a year to prevent the build-up of stagnant water that may foul your system. Read our blog, and the ASHRAE 188 guidance on the recommended cleaning windows and system treatment.

Educational Institutions Water Treatment

Millions of students and staff across the nation depend on proper water treatment for their water fountains, restrooms, and the heating and cooling of classrooms in their schools, universities, and administrative buildings. Proper water treatment plans must ensure these critical services function optimally without downtime to keep them safe. 

Chemstar WATER’s educational water treatment program looks at your total system, not just the chemical delivery side. We will help you design a unique plan to minimize costs and maximize efficiency with negligible dependence on water and energy. Our maintenance programs also take care of your investment with regular monitoring of your system to avoid premature equipment failure or repair costs. We know you have a lot to take care of, and we will guarantee you peace of mind by ensuring your water treatment system is monitored and maintained and providing safe heating, cooling, and potable water to your students and staff. 

To support your success, Chemstar WATER Superior Service offers the following:

  • Reduced chemical usage by utilizing equipment or solids rather than chemicals
  • Hands-free delivery of chemicals so that none of the university staff will handle chemicals
  • Sustainable Water Treatment Programs, such as using and installing on-site hypochlorite generators instead of biocides utilizing food-grade salt on-site, on-demand
  • Water Management Safety Program to ensure potable water treatment is well maintained to minimize Legionella.

Source of Legionnaires Disease

Often the primary source of Legionnaires Disease is determined to be the aerosolization of Legionella through showerheads; however, the aerosolized droplets from cooling towers carried through the building’s fresh air intake and those in ice machines may also pose a potential Legionella threat. Thus, comprehensive water treatment is critical for successful educational institution water treatment. 

ASHRAE 188 Standard

The ASHRAE 188 standard has outlined the buildings and systems that are most at risk of harboring Legionella. As Chemstar WATER, our goal is to guide our customers toward best practices that will minimize the threat of Legionella in their systems.  We strive to help our customers combat Legionnaires’ Disease and help them identify the risks associated with it.
