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 [...]
Reverse osmosis (RO) systems can seem intimidating. However, this technology has been around for decades and is used globally in all types of industries . Understanding the basics of how RO membranes work, and the mechanisms of the RO process are the first steps to system optimization. Types of Reverse Osmosis Membranes and Terminology First, let’s describe common terminology used in the [...]
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 [...]
Make your startup easier with a proper layup. Protecting your system during the winter season with the right layup program will significantly reduce the amount of chip scale that will loosen up in the spring, prevent corrosion and iron-throw, and greatly extend the life of your equipment. Kurita America offers four products that can be used for cooling layup: Protect 649, CTL-440, Cetamine [...]
Ever wondered what washing machines, healthcare equipment, smartphones, computers, and cars have in common? They all rely on the use of semiconductors, the powerful brains behind a variety of modern technology applications. However, a lot goes into making such semiconductors – from raw materials to ultrapure water – thus requiring continued investment in global semiconductor markets. Silicon [...]

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 [...]
As featured in Pumps & Systems Emerging contaminants, such as PFAS, are driving new treatment systems where they were previously not necessary. While it is tempting to address the need with a single treatment process, the composition of water is more than its concentration of regulated contaminants. The treatment approach should look beyond any single contaminant and consider the entire water quality to [...]
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 [...]
Nearly 50 years ago, the first identified cases of Legionnaires’ disease were confirmed during a convention of the American Legion in Philadelphia, Pennsylvani a. Since 1976, the study of how Legionella bacteria live, interact, and multiply in building water distribution systems continues to provide valuable information. Despite an increase in the understanding of the bacteria, the Centers for Disease [...]
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, [...]
