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.

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.

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 [...]

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 [...]
