Controlling dissolved oxygen (DO) levels during beverage production is vital for ensuring consistent product quality and shelf life. This is particularly true for canning, where high DO levels can cause breakdown of the can lining, corrosion and even leaking – which in turn can result in product waste and customer dissatisfaction. In some cases, can supplier warranties have exclusions for high DO levels.
Dissolved gases like NH3, H2S or NOx in waste water lead to contamination in the sewage system and high treatment costs for municipal waste water treatment plants.
Dissolved gas control in a nuclear power plant’s water system, including the primary make-up water storage tank and refueling water storage tank, can be essential to reduce radiation source term (defined as a release of radioactive material). In particular, controlling dissolved gases can also help reduce the formation of unwanted radionuclides, such as 14C and oxides of 60Co, and alleviate primary water stress corrosion cracking (PWSCC).
In the food and beverage industry, there is a growing awareness of environmental considerations wherever chemicals are used. In response, companies are trending towards alternative systems that operate with less chemical usage.
A major power plant in Thailand is using 3M™ Liqui-Cel™ Membrane Contactors to remove carbon dioxide from a DI water system. The system is an expansion project and will be used to feed a high pressure boiler. Liqui-Cel membrane contactors are being used to lower the CO₂ inlet into an Ionpure Electrodeionization (EDI) system. Carbon dioxide adds an ionic load to the EDI system, which can reduce the performance of the system. Manufactures of the EDI equipment suggest lowering the inlet CO₂ to reduce the load on the equipment and improve the water quality.
As engineers come under increasing pressure to reduce maintenance and operating costs, inefficient combination double-pass reverse osmosis and electrodeionization (RO/EDI) water treatment systems have begun to lose popularity as a means of providing ultra-pure water. Integrated membrane systems (IMS), on the other hand, combine multiple membrane-based water treatment processes into a single system. In this case study, find out how a heat and power plant in Northeast China lowered capital costs and energy use by adopting an IMS to replace its conventional water treatment system.
Preventing physical hazards in food continues to be challenging, and frequently, the reason for companies and/or regulatory agencies issuing recall notices. A brief review of the recalls viewable online at Recall.gov indicates that the number of recalls for physical hazards per month ranges from zero to eight involving USDA and FDA amenable products. This article will provide steps to help food companies keep physical contaminants out of food, as well detail the latest technologies helping to reduce physical contamination-related recalls.
This is part one of a two-part paper addressing the value of implementing a real time operations infrastructure to gain visibility, productivity, quality management, and real-time asset utilization.

In 1960, the Lafazanis family built its first winery in the south of Greece. Since then, the company has established a strong international presence in the Greek market, exporting its products to 10 countries around the world. Since its inception, Lafazanis has been devoted to crafting wines of exceptional quality.
