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.

Understanding Industrial Filtration

Waters from all over the world may contain suspended solids, microorganisms, and other unwanted contaminants that can cause damage to water systems. Heat exchangers, boiler tubes, cooling tower fill, system piping, etc. can become fouled without proper filtration. This results in a reduction in energy efficiency and increased maintenance repair costs.

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.

Guidelines for Inspecting a Boiler

The purpose of a boiler inspection is to provide assurance of equipment integrity to minimize safety issues with operating a pressure vessel. A minimal frequency is established by law and the Insurance Company that is covering customer liability in case of any operational failures. It has a useful secondary function of acting as an early warning of potential problems and determine the water treatment program’s effectiveness.

An internal boiler waterside inspection consists of all waterside areas of the vessel (e.g., steam and water areas, blowdown lines, feedwater connections, and low water safety devises) as well as dearators, superheaters, economizers, and blowdown heat exchangers. If possible, this inspection...

Understanding Cooling System Tests 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.

How Microbiological Filters Work

Understanding the Basics of Microfiltration

How Microbiological Filters Work

Hospitals and healthcare facilities are becoming more aware of the dangers of waterborne pathogens that can exist in their manmade plumbing systems. With growing concern of preventing infections, point-of-use (POU) filtration has been more frequently used in the healthcare market to aid in reducing bacteria counts found in water. However, not all filters are created equally, and it is important to understand the basics of microbiological filtration.

My Building Water System Tested Positive for Legionella: Now What?

We detected the presence of Legionella in one or more of our building water systems….. Now what do we do? This is probably the second most commonly asked question, surpassed only by:  “Do I have to test my water systems for Legionella?”  Often the question is posed this way:

“We recently performed Legionella testing on our building water systems and found one or more positive sample results.  What should we do about it?”
