The Chlorine Institute

There are so many interesting an informative websites in cyberspace now that it is hard to keep track. An interesting one for me is the Chlorine Institute which works with the Chlor-alkali industry. Chlorine is synonymous with water and wastewater disinfection, although it has enormous industrial applications. But those of you interested in the use of chlorine and its derivatives for water disinfection should check out this large and informative site. There is a particularly interesting section on Emergency Response. Link.

New Ozonation Book

There are some books that are just very good. Ozonation of Water and Waste Water by Christine Gottschalk, Judy Libra and Adrian Saupe is one of them. Ozone is not widely used in Ireland for either drinking water or wastewater treatment, and because of that my knowledge base is very superficial. However, the scope and clarity of this textbook, written in clear and accessible English, has excited a new interest in the area. I recommend it to you. ISBN: 978-3-527-31962-6. Published by Wiley-VCH, Weinheim in 2010.

 SODIS is short for solar water disinfection and is perhaps one of the simplest and safest ways of treating water in developing countries. Transparent plastic bottles (PET) are filled with settled water and left in the sun for 6 hours. A mixture of temperature and UV-A rays inactivate viruses, bacteria and protozoa making the water safe for consumption. It also works in cloudy conditions although it is recommended that the bottles are exposed to light for 2 consecutive days. 5 million people rely on this method for safe water.
