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 [...]

The High Cost of Corrosion: Is Your Plant At Risk, Part 2

UNIFORM CORROSION is characterized by a corrosive attack occurring evenly over the entire surface area of a large fraction of the total area. General thinning takes place until failure. On the basis of tonnage wasted, this is the most important form of corrosion. However, uniform corrosion is fairly easily measured and predicted, making disastrous failures relatively rare. The breakdown of protective [...]

The High Cost of Corrosion: Is Your Plant At Risk, Part 1

Corrosion is a naturally occurring phenomenon commonly defined as the deterioration of a substance (usually a metal) or its properties because of a reaction with its environment. Corrosion can cause dangerous and expensive damage to water and wastewater systems, pipelines, bridges and public buildings costing the U.S. according to a current corrosion study approximately $276 billion on an annual basis. Fortunately, [...]

When treating Thermal Energy Systems or Large Chilled Water systems the following standards should be followed to minimize costs to chemically treat these systems and protect the equipment assets. Filtration Use of Biocides Use of Corrosion Inhibitors General Maintenance and Monitoring Filtration  Given the size of these systems the most effective filtration is low micron sand [...]

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 [...]

Asset Protection & System Optimization: What You Need to Know

Asset protection is a concept that is steadily gaining notoriety in today’s industry. Many plants are looking for ways to optimize their system to get the most they can from their capital equipment, while simultaneously protecting their equipment and system from a variety of potentially damaging, and costly, variables including water quality, corrosion, and scale. Looking for the next level of service, [...]

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 [...]

Preventing Scale Formation in Reverse Osmosis Systems

Reverse osmosis (RO) systems behave similar to a boiler or a cooling tower in that they cause the dissolved salts in their make-up water to become more concentrated.  As pure water permeates the RO membrane, the salts are left behind in a concentrated stream. If the solubility of any particular salt is exceeded, the potential exists that the salt will form scale directly on the membrane surface or possibly within [...]

Benefits of Sidestream & Media Filtration in Cooling Towers

Cooling towers scrub large volumes of air and effectively remove solids consisting of dust, microbiological organisms, and various airborne debris. Make-up water to the tower adds suspended solids in the form of corrosion products, microbiological growths and wood fibers from the tower, and process leaks. If allowed to settle out, these solids can, and do, generate many problems within the system. With heavy solids [...]

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 [...]

Minimizing White Rust In Galvanized Cooling Towers

Galvanized coatings for cooling tower systems have been used in the industry since the 1950s. The galvanizing process binds a layer of zinc metal to steel. When properly applied and passivated, the zinc coating works as a nonpermeable sacrificial anode to prevent corrosion of the underlying steel structure. White rust, which is the oxidation form of the zinc coating, shows up as white spots and bumps on a galvanized [...]

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 [...]

Building A Brighter Tomorrow Today

After a devastating 7.0 magnitude earthquake shook the small country of Haiti on January 12, 2010, over three million people were left without access to safe drinking water. This natural disaster could not have hit a more vulnerable place as Haiti had the unenviable distinction of having the weakest water structure in the western hemisphere prior to the earthquake. There are two main issues surrounding water [...]

ZLD, A Sustainable Water Treatment Solution
