The Pursuit of a Green Carbon Steel Corrosion Inhibitor: Laying the Groundwork - Part 1

Abstract Corrosion control of carbon steel heat exchange components is becoming more important as energy costs rise and the demand for environmentally friendly chemicals is on the water technology forefront. This article explores the effectiveness of various inhibitors in open system cooling tower water that is both corrosive and scaling. Part 1: Laying the Groundwork gives an overview of the inhibitors tested and [...]

Why Should I Lay-Up My Cooling Tower?

Each year we get many of these questions from people, all stemming back to the central question of what is cooling tower lay-up and why do we do it? If any of these sound familiar to you then you may want to read on. “We wait to punch tubes until spring.” “I just drain the tower piping to the roof line.” “We leave the tower filled ‘just in case.'” “I [...]

Automation in Cooling Towers Reduces Water & Saves Hospital Thousands

With the State of California initiative to reduce water usage by 20% by the year 2020, many plants are focusing their responsibility to become a more environmentally friendly facility. One such facility included a large California hospital seeking to reduce the water treatment costs for their HVAC system. The hospital has three (3) individual cooling tower systems that service three (3) centrifugal chillers which [...]

Reduce Operating Costs Using Industrial Cooling Tower Automation

Efficiency, sustainability and conservation are all topics that must be considered in today’s business regardless of the industry. At the core of many businesses utility operations are cooling requirements that call for the use of a cooling tower. If allowed to operate in an uncontrolled environment, the water and energy efficiencies in cooling towers can be costly. Furthermore, an uncontrolled cooling tower [...]

The Sometimes Maddening Question of Boiler Lay-Up

With more and more steam boilers being asked to provide intermittent service, there is renewed focus on the proper treatment of boiler systems while they are offline. In the Power industry it is not uncommon for a combined cycle plant to operate less than 30% of the time, meaning the vast majority of the time the boiler is idle. The rise of renewable power assets that have intermittent and [...]

Reverse Osmosis (RO) Membrane Autopsy: What You Need to Know

A membrane autopsy is a good description of the analysis that can be performed on a fouled membrane. It can also be the key to determining how to prevent fouling of new membranes and to maximize the efficiency of this key piece of water treatment equipment. U.S. Water Services performs this analysis in-house at our location in Cambridge, Minnesota, and then issues a comprehensive seven page report of the results. The [...]

Flow Accelerated Corrosion

Few subjects have captured the attention of boiler cycle chemistry experts and research dollars in the past 10+ years as flow accelerated corrosion (FAC). Having previously been most concerned about failures occurring in higher pressure areas of the cycle, FAC is now a primary concern as over 60% of all utilities have reported finding it in their facilities.  Defined as localized rapid metal loss resulting [...]
