Water Treatment Challenges in Thermal Storage Systems

Water Treatment Challenges in Thermal Storage Systems

Thermal energy storage (TES) systems are cooling systems that can use ice banks, brine systems, or chilled water storage tanks to capture BTUs for the purpose of removing a heat load at another point in time. In practice, the chillers for the TES operate outside peak electrical load hours and store the BTUs in the preferred form for use during peak electrical load hours. This practice reduces strain on the electrical grid and provides both cost and energy savings for the owner.

Understanding Cooling System Control Ranges and Critical Parameters

Cooling towers are a critical component in many water systems, providing comfort or process cooling across a broad spectrum of technologies and applications. Cooling towers vary greatly in design and footprint, but all have the main goal: to provide removal of waste heat from processes or building systems. Control parameters are critical to maintaining any cooling system to improve water and energy efficiency, maximize equipment life expectancy, reduce hazards, and minimize downtime.

Legionella: To Sample, or Not To Sample?...That is the Question

What's required and what is my sampling plan?

Legionella: To Sample, or Not To Sample?...That is the Question

The simple answer is no (not directly), and here’s why:  There is no known safe level of Legionella in a building water system.  Therefore, even a non-detect sample result is not necessarily “safe.” The reason why is because the life cycle of this organism, coupled with the stresses put on it via temperature, disinfectants, etc. found within building water systems, may cause it to enter a viable but non-culturable (VBNC) state.

Chlorine and Bromine Testing In Cooling Tower Systems

Chlorine and bromine based biocides are widely used for microbiological control in cooling tower systems. These halogen compounds form strong oxidizing agents in water, which is how they kill bacteria and other microorganisms. Routine testing is important to confirm effective halogen residuals are maintained. Low residuals can result in poor microbiological control. High residuals can cause corrosion and destroy inhibitors.

Not All Water Supplies are the Same

How Blended Water Supplies Impact Water Treatment

Not All Water Supplies are the Same

The source(s) of water supplied to cooling towers, boilers, and processes may vary greatly daily or even hourly.  The impact this has on water systems must be closely monitored to avoid scale, deposits, corrosion, inefficient water usage, and other negative impacts on operational costs.
