Ion Exchange Technology Used to Treat Uranium in Nebraska

Bridgeport, located in western Nebraska, had previously been able to pump water directly out of the ground and into the distribution system, without needing to treat the water. It was later discovered that the water contained elevated levels of uranium, requiring treatment. Uranium can be naturally found in groundwaters, slowly dissolved over time from soils and sedimentary rock. Uranium is also a by-product of [...]

Pharmaceutical Plant’s Efficiency Improves After Correcting Boiler Issues

After working with their water treatment vendor for three years, a Southern United States pharmaceutical plant was unable to identify the source of boiler scale and low condensate return rate. The boiler scale and a low return rate were causing increased fuel and operational costs. U.S. Water conducted a plant survey to uncover the boiler system issue. Within a week of the initial plant survey, U.S. Water had [...]

Water Softener System Maintenance & Troubleshooting

A water softener system is one of a facility’s the best methods of defense against scale formation due to hard water on heat transfer surfaces, such as heat exchangers and boilers. In addition to a savings in energy, water and chemical costs, a well maintained softener can extend piping and equipment life. Some of the most common issues an operator may experience when maintaining water softener equipment is [...]

How Does Piping Design Affect Bacteria Growth in Water Systems?

Q&A with U.S. Water’s Project Manager, Jason Mitchell   What is high purity water, and where is it used? High purity water, also referred to as ultrapure or deionized water, must comply with quality requirements to sustain specific production goals and standards. It is used in a variety of industries where bacterial contamination is strictly regulated such as biopharmaceutical, [...]

Bacteria Prevention in High Purity Water Systems, Part 3

SANITIZATION USP recommends the installation of “corrective facilities” in piping systems as a way to handle bacteria levels in water systems. These would include “access to the system for sanitization or introduction of steam, ozonation, chlorinators, storage at elevated temperatures”, etc. This is mostly commonly needed for smaller less advanced manufacturing facilities or highly regulated [...]

Bacteria Prevention in High Purity Water System, Part 2

SYSTEM DESIGN & BACTERIA PREVENTION Identifying and treating potential problems of bacteria formation once a system is operational can be much more difficult than addressing them during the system design. Bacteria ultimately grows by feeding off of nutrients in a system and water is a great medium for bacteria to grow since it can be a significant source of nutrients. Therefore, to prevent growth of bacteria [...]

Bacteria Prevention in High Purity Water System, Part 1

Maintaining a consistent level of quality is the goal of any process and high purity water system is no exception. Industries such as biopharmaceutical, electronics, manufacturers, hospitals, laboratories, power generators and many others require ultrapure or deionized water in their manufacturing and research. These high purity water systems must be exceedingly reliable in their ability to meet the quality [...]

Optimize Your Industrial Water Softener With A Brine Elution Study

Sodium zeolite softening is an ion exchange method for removing hardness from water sources achieved by exchanging calcium and magnesium ions for sodium. This process is ideal when applied to domestic, commercial and industrial water softening due to useful purposes such as filtering, odor removal and ion exchange. When a softener with fresh resin is in service, the sodium ions in the surface layer of the bed are [...]

Can Your Plant Benefit From Upgraded Steam Equipment?

Steam quality is a measure of the amount of liquid water contained in steam generated by a boiler. It is often expressed as Percent Dryness. Typical low pressure boilers have a Percent Dryness of around 99%, which means that there is 1% moisture in the steam. That 1% is important, because moisture, in the form of condensate, contains less heat energy than dry steam, and as a result a pound of wet steam does less work [...]
