Electrolysis – A Green Technology For Water Treatment
The conventional drinking water disinfection methods, which have seen extensive use, include chlorine gas disinfection and chlorine solutions. The advantage of these methods is in the vast amount of experience gained over the years. However they do suffer from serious disadvantages, including the cost of the material, especially in liquid chlorine facilities, and the large investment required for protection and safety equipment in chlorine gas facilities besides the cost of material. Recent years have seen a rise in the importance of "green" technologies for protecting the environment and for decreasing the use of various chemicals. This article discusses the use of electrolysis as one of these technologies...

Case Study: Bringing Efficiency And New Confidence To BOD5 Analysis
BOD5 testing used to be a time-consuming and inefficient procedure for the Nacogdoches, TX, Wastewater Environmental Laboratory, requiring continuous instrument membrane replacements due to problems with instrument drift and slow measurements. With the adoption of new, breakthrough luminescent technology BOD5 testing for the lab has become more accurate and easier...
