Dear Industry Colleagues, Greetings from Water Today!I am working on the January 2019 issue and would like to invite you to contribute technical articles, case studies, research papers on “ Filtration Technologies & Systems A Growing & Relevant Market” and facilitate a comprehensive perspective on the same. Please find below the theme note and do let us know if you could send us your article.Theme Note - Filtration Technologies & Systems A Growing & Relevant Market – Jan 2019 issueToday, about one billion people in the world do not have access to clean drinking water. With ~3.5 million of those people dying each year, this is no longer an issue we can pretend is of little importance. Of the deaths that occur each year, 84% are those of children and 98% occur in developing countries. Many companies have created water filtration technologies targeted for the population most affected, that is, those living in developing nations. Besides, the demand growth worldwide for water is placing a burden on available resources and creating competition among industrial, agricultural and municipal users. At the same time, environmental regulations continue to impact water intake and effluent purity. These pressures are motivating an interest in filtration technology to process wastewater so that it can be reused rather than discharged into the environment.Filtration is the most effective type of water treatment and purification currently available. The process of filtration involves the flow of water through a granular bed, of sand or another suitable media, at a lowd speed. This type of slow filtration over a granular bed is generally known as slow sand filtration. It is the oldest method of filtration but still widely used in municipal water treatment plants today. More modern filtration systems use carbon as the main constituent material of the filter. This carbon is compressed into a solid block form, as opposed to the more loosely structured, granular, sand filters. Such filters often include other media substances, in addition to the compressed, solid carbon. This type of water filter is known as a multimedia filter. These filters clean water through both physical and chemical processes. Water is generally directed through several stages carbon and multimedia filters to ensure the removal of all unwanted materials. The first filtration stage will remove the most concentrated chemicals, like chlorine, while subsequent stages will remove smaller and more evasive chemicals, like pesticides. With these filter technologies, we have different options to choose from. Nevertheless the most obvious evolutionary trend in filtration technology today is the rise of nanotechnology that has created a need for removing particles of 100 nanometers or even smaller, and the filtration industry has responded with solutions capable of capture down to the ionic and atomic levels. Support for such small particle sizes does not come without its drawbacks though, as such membranes are extremely susceptible to damage and fouling from larger particles and debris. Thus, with all new and high-powered filtration technology coming to market to choose, a complete understanding of the filtration needs is required to ensure the proper specification of a solution for a given application. This issue will focus on the growing and relevant market of filtration technologies and systems. We would like to invite you to share your experiences in the form of articles, technical papers and case studies with our readers. Please inform us of your intent to contribute at the earliest, so that we can evaluate the articles for the publication.
