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...
