A large food and beverage facility in the United States was facing increased costs from hauling away a full dumpster of sludge every week. The facility’s wastewater came from their production process, and the organic materials needed to be separated before being discharged back to the city. The costs for these types of services can vary between $600 and $1,500 per trip to dispose of the sludge, but costs [...]
An electronics company in the United States was facing high aluminum corrosion rates and treatment costs in their process cooling water systems due to the previous water treatment program. The previous program resulted in high conductivity and high pH, which no longer met the specifications of 50 microsiemens (µS) and a pH of 6.5 to 7.5. Low conductivity is required for process cooling water tooling [...]
A United States Midwest dry grind fuel ethanol plant requested Kurita America to assist and implement production efficiency improvements within their plant. After an in-depth performance evaluation, the Kurita America Process Technologies team identified a number of opportunities to improve efficiencies and output quality, after observing limited plant throughput due to slurry flow restriction, plant downtime [...]
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 [...]
As featured in Water Technology 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 [...]
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 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 [...]
A washing machine manufacturer 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 and in the molding process to [...]
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 [...]
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 [...]

A biofuels plant in the midwestern United States was starting up with a traditional, 120 million gallons per year (MGY) design for a new plant. Kurita 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 [...]
An adhesives manufacturer, a Kurita customer of over 10 years, 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 what is accepted for [...]
