Cooling Tower Spring Maintenance

Winter layup of cooling towers can create an environment susceptible to growth and incubation of corrosion causing bacteria. Cooling tower cleaning and maintenance prior to spring start-up is recommended by OSHA to remove biofilm and prevent Legionella bacteria, and by most cooling tower manufacturers to maintain system efficiency during the summer cooling season. Cleaning and disinfecting the cooling tower basin [...]

Design and Care of Reverse Osmosis Systems, Part 3: Operation and Monitoring

Reverse osmosis (RO) systems offer power plant owners and operators a reliable and well-proven water treatment solution. However, designing and caring for an RO system requires a thorough understanding of a plant’s water supply and the technology’s capabilities. The final article of this three-part series will address RO system operation and maintenance best practices. Section one and two of this [...]

Design and Care of Reverse Osmosis Systems, Part 1: Design

Reverse osmosis (RO) systems offer power plant owners and operators a reliable and well-proven water treatment solution. However, designing and caring for an RO system requires a thorough understanding of a plant’s water supply and the technology’s capabilities. Part one of this series will review the importance of water samples and pilot studies as plant engineers begin to design an RO system to match [...]

Protecting Your Power Plant from Corrosion During Downtime

In the Power industry, every minute is critical. A smooth plant start-up is vital to operations, and directly linked to lay-up procedures. A thorough understanding of critical lay-up and start-up strategies & procedures, paired with a proper corrosion control protection program can prevent unscheduled downtime, reduce operating costs and increase plant reliability. In the gas fired combined cycle market, [...]

Power Plant Water Treatment System Restored After a Decade of Non-Use

After ten years of inactivity, a midwestern combined cycle power plant needed to bring its water treatment system back into operation. The previous equipment had been sitting idle after the previous owner went bankrupt, and required major cleanup and upgrades. While other water treatment companies were offering a chemical exclusive program, it was evident the plant would require a complete integrated solution to once [...]

Greenfield Water Treatment System Reduces Chemical Handling & Improves Efficiency

The coal-fired Alliant Energy/Interstate Power and Light, Lansing Generating Facility's (LAN) water treatment system was over 40 years old. Nearing the end of its life expectancy, the antiquated water treatment equipment was suffering from excessive corrosion, limited replacement part availability and a variety of retrofit materials. Acid and caustic chemicals were used in the existing ion exchange system, [...]

SBL Interview: Power Today

Joe Tirreno, U.S. Water’s Strategic Business Leader – Power, sat down with Power Today’s Cassie Haley during the 2016 PowerGen International Conference. During this short interview,  Joe discussed U.S. Water’s integrated water management solutions and water use trends in the power industry…

U.S. Water’s PhosZero™ Program Improves Corrosion Rates and Meets Discharge Limits at Power Plant

A Midwest power plant was experiencing scale and white rust build-up inside their cooling tower condenser tubes, creating obstacles cooling the inverter. If left untreated, the build-up could result in a costly asset replacement and unscheduled down-time. The Minnesota Pollution Control Agency (MPCA) was also in the process of instituting new phosphate discharge limits, which encouraged plant management to take [...]

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 [...]

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 [...]
