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 [...]

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, [...]

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 [...]

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 [...]

Ozone Generators: A New Technology for Biocide Treatment

The use of Ozone has become an optional biocide in smaller cooling towers, evaporative condensers and process applications where low to moderate traditional biocides, such as bleach and bromine,  have been used. Facilities seeking ‘green' solutions are using Ozone to reduce chemical discharge, reduce on-site chemical handling by workers, and provide a hands off treatment approach, especially in hard to [...]

Introducing U.S. Water Energy Services

U.S. Water Services, Inc is pleased to announce the launch of  a new division, U.S. Water Energy Services, to focus on the Upstream Oil & Gas Sector with down hole treatment for scale and corrosion, water reuse and remediation. The intent of this new division is to improve well production and minimize, or eliminate, environmental impact. The natural gas production industry continues to expand their operation [...]

U.S. Water Announces COR™, Corn Oil Extraction Product Line

Corn Oil Recovery (COR™) is an enhancement additive designed to increase the removal of corn oil from mechanical separation systems at dry-mill ethanol plants from U.S. Water’s Ethanol Process Technologies (EPT) team.  The product will benefit all ethanol facilities that have existing corn oil separation equipment, or are contemplating corn oil separation equipment in the near future.  We have [...]

Reverse Osmosis (RO) Best Practices & Standards

Reverse Osmosis (RO) is a proven technology with new applications for various industries. U.S. Water’s representatives pride themselves on having extensive knowledge of RO unit installation, operations, troubleshooting and cleaning procedures. Let’s review the standards and best practices for RO units by first reviewing the process of osmosis. OSMOSIS: A NATURAL OCCURRENCE Osmosis is a natural [...]

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 [...]
