Filtration within food and beverage processing, is a safe and economic method for removing impurities and extending the shelf life of many consumable products. High cleanliness standards and stringent contamination control is of utmost importance within the industry, ensuring the manufacture of superior quality produce, a significant reduction of waste and a minimum of product ...

The reference EN 13284-1 provide two different way about stack sampling, depending on emission conditions. The first option provide sampling with a standard probe with inserted perpendicularly into the duct filter holder to the emission flow. This option is recommended for emissions not involving humidity and with low temperature. It allows using non-perpendicular filter holders to sampling flow, reminding to consider also as part of the sampling all the collected parts ahead of the ...

Dioxin, PCDD-PCDF and PCB sampling system compliant with UNI-EN 1948:2006. This sentence refers to the last variation of the version dated 1999 because it has been changed some phases in the technical-analytical process and there are new normative references about oxygen sampling (EN-14789) and humidity content (EN-14790). ...

The Oil & Gas industry in North America, driven by hydraulic fracturing (or fracking) technology and operations, is facing a water shortage and storage crisis that can shut down an operation as fast as a dry well. Fresh water is limited by transportation cost, municipal regulations, and drought. Regulatory pressures, driven by health concerns, have created a business environment where sealing reject water from extraction operations into deep wells has become a limited ...

The semiconductor, microelectronics, solar cell and solar panel manufacturing industries use large volumes of process and ultrapure water. The processes using this expensive water often leave contaminants that can be very difficult to remove using conventional water treatment. These include die sawing and backgrinding grit, dissolved metals, fluoride and other ...

High fluoride levels in wastewater can be problematic for industries using hydrofluoric acid (HF) as a cleaning agent or etchant, such as the semiconductor, solar cell and metals manufacturing industries. HF is also used as a reactant or catalyst in the plastics, pharmaceutical, petroleum refining and refrigeration industries. Fluoride concentrations from these industries may range from 100 to more than 10,000 ppm in rinse waters, but discharge limits are often below 20 ppm. ...

High Solids Filtration - SDI/Solids Reduction: The two (2) main technologies used to reduce suspended solids are clarification and media filtration. Clarifiers require a high level of monitoring and supervision to prevent the passing of large slugs of solids due to temperature and chemistry upsets. In addition, the organic polymers used in clarifiers (to promote flocculation), can also cause problems. An excess of these polymers will foul downstream filtration equipment such as RO membranes or nanofilters. Since ...

Our Filters are Highly Resistant to Corrosivity. Reverse osmosis is one of the most widely applied desalination technologies. Previous to the process of separtion of water from salt and minerals, seawater or brackish wter requires the elimination of large size particles in order to assure a good performance of reverse osmosis membranes. Our sand filters facilitate the removal of these suspended solids to avoid membrane fouling. In addition, after ...
