In 2006, a groundbreaking ethanol plant began operation in the San Joaquin Valley of California. As one of the world’s most productive agricultural areas, this was a prime location; however, to address environmental challenges, the region had strict regulations on industrial discharge streams. To make this plant a reality, Kurita America designed a unique water system that required no environmental discharge, a [...]

Dirty and fouled cooling tower water often plagues maintenance teams that manage industrial cooling towers. A dirty cooling tower can have a detrimental effect on the overall health of the plant’s water infrastructure, leading to lower efficiencies and increased costs. Cooling water full of fine sand, grit and biological matter can contribute to damage to analytical instrumentation, creating inaccuracies and [...]
Water is vital to the operations of our customers who entrust Kurita America to provide the best solutions for managing their water resources. Understanding how water integrates into the bigger picture allows us to approach your water challenges from multiple angles and develop programs that deliver the most effective results; increasingly these involve some level of water reuse. Whether enabling the use of graywater [...]

Bacterial infections during fuel ethanol fermentations can negatively impact the fermentation process and lower ethanol yields. Lactic Acid-Producing Bacteria (LAB), such as Lactobacillus , Lactococcus , Weissella and Pediococcus , are a common source of contamination due to their ability to grow in the harsh conditions, low pH, high temperatures, and high concentrations of ethanol, present during fermentation. [...]
In the recent edition of Opflow magazine, a publication by the American Water Works Association (AWWA), co-authors T.J. Stroebl (Kurita America, AWWA MAC Vice Chair) and Randy Moore (Tnemec Company, AWWA Innovation Initiative Co-Chair) discuss the nexus between asset management and sustainability practices, and how goals related to both can be achieved through a properly structured procurement program. Having a [...]
Galvanized coatings for cooling tower systems (cooling towers, evaporator tube bundles, etc.) have been used in the industry since the 1950s due to their relatively low cost and long service life. The galvanizing process bonds a layer of zinc metal to steel. When properly applied and passivated, the zinc coating works as a non-permeable sacrificial anode to prevent corrosion of the underlying steel structure. White [...]
Time spent getting a cooling tower cleaned and prepared in the spring will result in more reliable and efficient operation throughout the summer cooling season. Towers that have been off-line during the winter months can collect dirt, debris, bacteria and other contaminants from the environment, if not laid up correctly. This buildup can produce corrosion, equipment failure, biological fouling and microbiological [...]

Water. We can’t live without it, and you can’t run a food or beverage plant without it. However, having it available for all earth’s inhabitants worldwide in the next 20 to 30 years will be a challenge—as already two-billion of the planet’s population live in areas where water is scarce. Unsurprisingly, the food and beverage industry is one of the largest water users, so it’s well [...]
Many biofuel plants are working toward efficiency and plant optimization to increase ethanol production. Often when plants move forward with expansion efforts, the adverse impact on system efficiencies, such as cooling, is overlooked. Without proper evaluation of the existing cooling system operation, plants could spend additional capital on an unnecessary cooling tower expansion or experience an increase in [...]
Programmable Logic Controllers ( PLCs ) are industrial digital computers that were adapted to control manufacturing processes, such as assembly lines, robotic devices or any activity that requires high reliability, ease of programming and process fault diagnosis. The first PLC system was installed at a General Motors manufacturing plant in the early 1970’s, which allowed for a more proficient way to modify the [...]

A successful water-management program for a process cooling water system will rely on a number of factors, some of which may be overlooked or ignored until a problem arises. There is much to consider in order to keep equipment operating efficiently, minimize rejection rates, prevent corrosion-related failures, conserve water and energy and reduce the risks associated with waterborne pathogens such as Legionella .
