Hospital Reduces Corrosion Rates by 62% with Kurita’s Low Phosphorous Tower NG for Cooling Water

A large hospital in the United States was using traditional cooling water treatment technologies, supplied by another water treatment provider, to control deposits and corrosion in their systems. The local water contains ions that create both corrosive and scaling conditions. Moreover, discharge limitations for phosphorous were becoming a higher concern due to tightening regulations. The hospital’s [...]

Meat Rendering Facility Enhances Tallow Recovery Process and Increases Revenue with Kurita’s Program

A meat processing facility in the Midwest had over seven percent fat in their stick water sent back to the dissolved air flotation (DAF) systems . Stick water is the heavy liquid phase should be free and clear of any tallow or suspended solids. Separator inefficiencies result in high proteins and other nutrients in the stick water being recycled back to the front of the treatment process, requiring additional [...]

Hospital Reduces 290,000 Pounds of CO2 Emissions Per Year with EnergyOUT™

A Central Florida hospital was expanding their new central energy plant while phasing out an older steam plant. The hospital also has been experiencing significant condensate loss, and many of the heat exchangers were experiencing higher corrosion rates. The condensate loss also caused issues of controlling the pH level, which can corrode piping and equipment. This all accumulated into additional costs due to [...]

Seiko Epson Reduces Water Usage by 10 Million Gallons per Year with Kurita's Reuse Plan

Seiko Epson in Japan produces and sells printers and related products, and as part of its management philosophy to be “an indispensable company,” the facility is working to solve social issues through its business activities. At each business site, the company was working to reduce its environmental impact. Seiko Epson wanted to reduce plant water usage and greenhouse gas emissions and achieve [...]

Washing Machine Manufacturer Saves $130,000 Annually with Kurita’s DReeM Polymer™ for Boilers

A washing machine manufacturer in the United States of America had accumulated a large amount of scale on their boilers, which was affecting their fuel consumption, overall costs, and steam efficiency, resulting in frequent boiler shutdowns. The manufacturer had two 600 horsepower firetube boilers that produced approximately 289 million pounds per year of steam. The steam was primarily used for styrene bead expansion [...]

Kurita America’s EZ Feed System Improves Tire Manufacturing Plant Safety and Chemical Control

A tire manufacturer in the southern United States was facing issues in their eight water baths that are used to cool the rubber after it has been extruded. The water chemistry in the baths must be maintained within the machine and equipment standards (MES), so that the finished rubber maintains its strength. Historically, the manufacturer had been trying to maintain these parameters manually, which presented challenges [...]

Meat Processing Plant Saves $35,000 Annually with Kurita’s Cetamine® E Series for Cooling Water

A meat processing plant in Texas was using traditional cooling water treatment technology to control deposits and corrosion in their critical evaporative condenser system. After years of poor control of the existing water treatment program, the plant personnel observed scale formation. Calcium carbonate had accumulated on the heat exchange surfaces. This put a strain on the cooling system, which impacted plant [...]

Kurita’s Cetamine Success at Renewable Energy StartUp

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 [...]

Adhesive Manufacturer Saves $50,000 per Year with Kurita’s DReeM Polymer for Boilers

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 [...]

Distillery Saves over 500,000 Proof Gallons per Year with Kurita’s ProClean 815

A large distillery in Kentucky had been working with Kurita 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 evaporators, [...]

HMO Technology Used in Midwest to Reduce Waste

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 [...]

University Removes Legionella through Kurita America's Monochloramine Solution

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 [...]
