| Decentralised Solution to Secure Drinking Water Supply in Remote Brazil Dr. Dipl.-Ing. Mag. Wolfgang K. Walter, Dipl.-Biol. Jörgen Hößler Together with the Brazilian partner COPASA, one of the largest water supply companies on the Latin American continent, Grünbeck Wasseraufbereitung GmbH, is testing mobile drinking water supply solutions for remote regions. An article in the part “Science” of this gwf issue describes the background of the project. |
| Fundamentals of pH Measurement Ă–znur Alp A wide range of possibilities are available for measuring pH values, including colorimetric, photometric, and electrochemical methods. Diff erent measuring processes may result in diff erent measurement results, all of which are in principle correct. To prevent any confusion in this regard, national and international standards specify that pH values are measured electrochemically with a glass combination electrode. |
| Reliable Water Supplies Marc Wevers As one of the world’s leading manufacturers of tufted and printed polyamide carpets, Imperial Tufting Company (ITC) requires large volumes of water for their manufacturing process. To activate and control their own wells and pumps, this Belgian company uses controller technology from Phoenix Contact that communicates with peripheral devices connected via Profi net. The existing Ethernet infrastructure is used for this purpose. |

| Energy Efficiency in Wastewater Treatment Systems Stephan Brand To “Save money“ is the order of the day – especially due to permanently rising energy expenditure. This is of course also applicable for the cost balance of wastewater treatment plants the yearly cost of which may compose at 55 % from capital and at 45 % from operational costs. These operational costs will consist of payroll costs (45 %), material (10 %), services of other companies (8 %) and various others (5 %). This means that almost a fi fth of the operational costs of a wastewater treatment plant are used for energy. Considerably more than half of them – approx. 60 % – are required for the blower station for biological cleaning. But not only energy costs, also payroll costs and costs for services of other companies highly depend on the chosen compressed air supply. |
