U.S. Water Services, Inc (U.S. Water) a leading provider of integrated water and process solutions for industry, is pleased to announce the acquisition of Water Chemical Service, Inc (Waterchem). Founded in 1984, Waterchem provides water treatment chemical and engineering services for the Eastern United States. Located in Maryland and servicing the [...]
With the State of California initiative to reduce water usage by 20% by the year 2020, many plants are focusing their responsibility to become a more environmentally friendly facility. One such facility included a large California hospital seeking to reduce the water treatment costs for their HVAC system. The hospital has three (3) individual cooling tower systems that service three (3) centrifugal chillers which [...]
Efficiency, sustainability and conservation are all topics that must be considered in today’s business regardless of the industry. At the core of many businesses utility operations are cooling requirements that call for the use of a cooling tower. If allowed to operate in an uncontrolled environment, the water and energy efficiencies in cooling towers can be costly. Furthermore, an uncontrolled cooling tower [...]
U.S. Water’s Ethanol Process Technologies (EPT) team engaged in a CO2 Scrubber performance comparison evaluation in an Eastern United States dry grind fuel ethanol plant with a 100 MMgpy nameplate. Parameters compared were: Compliance Reliability Application Cost Residual Bisulfite – and its impact on both yeast vitality and final product sulfur content Accompanying Value The EPT [...]

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 [...]
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 [...]
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 [...]
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 [...]
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 [...]
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 [...]
