A biofuels plant in western Iowa was starting up with a traditional, 120 million gallons per year (MGY) design for a new plant. Kurita America bid on the start-up plant, proposing Cetamine® in conjunction with a caustic alkalinity booster. The plant was pre-qualified for Cetamine use. Cetamine is part of Kurita’s creating shared value (CSV) product line that benefits the customer and [...]
An adhesives manufacturer, a Kurita America customer of over 10 years, in the Upper Midwest utilizes three water tube boilers for its steam supply and produces 85,000 pounds an hour of steam. The make-up water for steam generation is prepared using a reverse osmosis (RO) system followed by sodium zeolite softening. Since the city’s makeup water can contain calcium levels that are hundred times higher than [...]
A large distillery in Kentucky had been working with Kurita America for approximately eight months and was producing about 8.7 million proof gallons of distilled spirits annually. Fouling is expected in a distillery due to high mineral content of a plant’s water supply. This particular distillery was facing fouling in the evaporators because of high concentrated mash solids and high temperatures in the [...]
A city in the midwestern United States needed a new groundwater treatment system to replace an aging system that relied on reverse osmosis (RO) to remove radium, a primary drinking water contaminant. This project used a design-build, collaborative delivery approach, and Tonka Water, a Kurita brand, partnered with a consulting engineer and a local contractor to help design a high-efficiency system that met the [...]
For the past five years, Kurita America has been partnering with a major university on the east coast of the United States for their water treatment needs. Due to COVID-19 , the university was facing a heightened Legionella risk after a year and a half shutdown of the campus. Because of remote learning during the pandemic, many of the buildings were not in use, specifically without the water being circulated. The [...]

A food processing facility in the Upper Midwest was experiencing an upset due to a breakdown in their process equipment and production changes, which allowed for a high level of fats, oils, and grease (FOG ) to pass into their waste stream. The additional FOG that was discharged into the aeration basin was not sufficiently removed during the primary treatment. The increased loading to the aeration system put a [...]
Sartori Cheese, a Wisconsin-based world-class cheese producer known for their SarVecchio® Parmesan and BellaVitano® cheeses, collaborated with Kurita America to take a proactive approach to review Sartori’s water consumption, production, cleaning practices, and wastewater discharge at their production facility in Antigo, Wisconsin. Through the Comprehensive Site Assessment (CSA) and in alignment with [...]
Severe drought inspired a southern California university to explore their water use and to implement aggressive sustainability goals. Treatment and reuse of cooling tower blowdown water was instrumental in their water action plan, and Kurita America has played a key role in this effort. Southern California is population-dense and water-scarce. Although the bottom two-thirds of the state accounts for 80 percent of [...]
At an ammonia production facility located in rural Nebraska with surrounding cornfields and gravel roads through the facility, the cooling tower collected high amounts of solids and silt through the natural air scrubbing of the system. These suspended solids circulated through the cooling system and accumulate over time. No filtration system had been installed to remove these suspended solids, thus the number of [...]
A new Midwest dry-mill ethanol plant needed a complete boiler treatment program in place for the initial startup. The facility required a safe and FDA-approved product for potential contact in Distillers’ Dried Grains with Solubles (DDGS) used in animal feed and corn oil. Using efficient chemical feeds with minimal operational maintenance was priority. Additionally, this facility's two boilers had sustaining [...]
The City of Elkhorn is a long-standing customer of Kurita America, utilizing equipment at multiple water treatment plants since the late 1970s. Elkhorn’s existing water treatment plants used aeration followed by pressure filtration and ion exchange, in series, to remove iron, arsenic and radium from the groundwater supply wells. When it came time to replace an aging treatment system, the city wanted to include [...]
Craven County is located in the Eastern part of North Carolina at the mouth of the Neuse River. Their new water treatment plant was to include a reverse osmosis/nanofiltration (RO/NF) membrane system; however, the small membrane pore size removes many beneficial minerals, often resulting in a corrosive water. To stabilize the water before sending to distribution, Kurita America furnished a calcite contactor [...]
