A new liquid hydrogen production facility was built to meet increasing demand from fuel cell electric vehicles (FCEVs). Hydrogen is produced using steam, which requires demineralized water to protect asset integrity and product quality. The plant needed a robust pre-treatment system to convert the municipal water supply to suitable demineralized standards. Hydrogen is known as an “energy [...]
A large hospital has a campus wide seasonal chilled loop with approximately 75,000 gallons total volume. It was being treated using a traditional silica and azole-based corrosion inhibitor package. Corrosion coupon rates with the traditional inhibitor program were considered excellent for both mild steel and copper, yet each spring during startup, iron levels were found to be five to ten parts per million [...]
Featured on Water Technology A global manufacturing company producing fiberglass insulation was constantly reusing their water . Creating fiberglass is a process involving small glass particles heated to their melting point before passing through a spinner, which creates the fibers of glass. After this process, cooling is necessary requiring a large volume of water. For this cooling process, the [...]
The City of LaSalle, Illinois, has worked with Tonka Water, a Kurita brand, since their filters were installed in 1992. After nearly 30 years of service, the city was assessing how to ensure a similar duration of additional life. In lieu of a full replacement, they decided to refurbish the existing filter equipment. The city’s water treatment plant had two Tonka Water horizontal pressure filters for [...]
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 [...]
