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.

All About Deaerators

Steam boilers do exactly as their name implies, they produce steam; however, may factors must be considered and managed to do this, including corrosion, scale, water minimization, fuel efficiency, safety, and Total Cost of Operation. Boiler feedwater often contains dissolved gases, such as oxygen, carbon dioxide, and ammonia. These dissolved gases are problematic for the boiler system because they may cause corrosion, leading to equipment failures (e.g., carbon dioxide can form carbonic acid in boiler condensate, lowering the pH, and corroding the condensate piping). To minimize corrosion, the dissolved gases must be removed or neutralized. This can be achieved through the use of deaerators, which work to remove such dissolved gases to low levels reducing the amount of follow-up neutralization required (e.g., sulfite-based oxygen scavenging).

Legionella Control Policy vs Water Management Plans

We are often asked to review, audit, improve upon, or otherwise comment on Water Management Plans (WMP’s) consisting of no more than a few pages of boilerplate text which, in reality, are actually NOT Water Management ‘Plans’ at all.  Rather, they are simply Legionella control policies.

So, what’s the difference between a “Policy” and a “Plan”?

Policy (always a noun):  a course, principles, rules, guidelines, etc., proposed or formulated by an organization, government, business, or individual, typically published or promulgated throughout the organization, in order to direct organizational behavior towards (or away from) a particular goal, objective, or condition.

What is PPM?

The phrase “Part Per Million” is a term we use to describe very small amounts of something in a much larger amount of something else. Here are some examples of one part of something in a million parts:

Water Crisis in America

What We Can Learn from Flint

Water Crisis in America

On a recent episode of the Public Broadcasting Systems’ Frontline “Flint’s Deadly Water,” investigative reporters looked deeply at the city of Flint from 2014 to now in hopes of identifying the true causes of the water crisis and the cause of the many deaths. As an outsider, we immediately associate Flint with a lead crisis, which undoubtedly remains an issue. However, Frontline finally dives deeper and states that Legionnaires Disease is the true public health crisis that happened in Flint. Below is a summary of the research they did and their findings.
