COVID-19 and the Internet of Water Treatment

COVID-19 has brought the phrase “social distancing” to the forefront, and many locations won’t allow nonessential employees or vendors on site at all.  Not only has this changed the world we live in, but the outbreak has changed the value proposition for water treatment controls and services.  It has forced us to proceed quickly into the future.

Addressing Stagnant Water in Buildings Due to COVID-19 Shutdowns

As coronavirus continues to spread across the country, many facilities including college dorms, hotels, vacation condos, shopping malls, and other buildings are being shut down unexpectedly or operated with very low occupancy.  As a result, building water systems that normally have hundreds or thousands of gallons of water flowing through the fixtures, piping, and equipment daily may be stagnant for an unknown period of time, maybe several months.

Where Should I Sample for Legionella?

Should your Water Management Plan (WMP) Program Team decide to utilize environmental water sampling to validate the effectiveness of the WMP, ANSI/ASHRAE 188-2018 advises that these tests should be performed by a laboratory accredited to a nationally or internationally recognized standard (e.g., ISO/IEC 17025:2017), with Legionellaa included in the laboratory’s scope of accreditation.

Before environmental sampling is undertaken, a Sampling Plan should be formulated.  This plan should list the devices and Points of Use (POUs) to be sampled, at what frequency sampling will be performed, what the acceptable control limits will be, and what the response protocol will be for any sample result(s) falling outside of the previously-established control limits.

Steam Quality vs Steam Purity

Steam quality and steam purity are topics which often get confused with each other.  Distinguishing the difference between the two will help you understand the unique impacts they have upon a steam system.

Understanding steam quality requires understanding vapor-liquid equilibrium in water. As heat is added to subcooled liquid water, it proceeds to the saturated liquid curve and becomes a saturated liquid (moving from incoming city water to point A). At the saturation point, any heat added to the water will form a vapor and the temperature will remain the same because all additional enthalpy (heat energy) being added to the system is being used to change the phase of the water from liquid to vapor.

How Chillers Work

Factories, warehouses, healthcare facilities, commercial buildings, and office spaces generate unwanted heat that must be removed from the process, equipment, or occupants inside. Chillers may be used to remove this heat by transferring it to the atmosphere either by air or water cooled chillers. At the heart of the chilling process is the evaporation of a liquid refrigerant into a gas. Two basic types of chillers include vapor compression and absorption. In this blog, we will focus on the vapor compression chiller.
