Endress + Hauser Announces The New ISEmax Ion-Selective Measuring System
<p>Endress+Hauser's new ISEmax CAS40 system for measuring ammonium and nitrate is based on potentiometric measurement with ion-selective electrodes. It makes the processes of nitrification and denitrification transparent particularly in the area of wastewater treatment. It also significantly reduces the costs for power used in aeration systems.</p> <p>ISEmax measures the concentration of ammonium and nitrate quickly and continu-ously in municipal waste water treatment plants. The robust in-situ measurement allows measuring several parameters simultaneously with one sensor. A distinguishing feature of ISEmax is its short response time. Since ISEmax is immersed directly into the measuring so-lution, the measuring system responds very quickly to changes in the concentration. The rapid trend display supports the early control and regulation of the processes.</p> <p>The unit is easy to use: the measuring system does not use any chemicals, is low-maintenance and does not require external sampling. Furthermore, integrated automatic com-pressed-air cleaning prevents the membranes from fouling.</p> <p><b>ISEmax covers a large measuring range:</b></p> <ul> <li>Ammonium-nitrogen: 0.1 - 1000 mg/l NH4-N</li> <li>Nitrate-nitrogen: 0.1 - 1000 mg/l NO3-N</li> </ul> <p> </p> <p>Typical applications in municipal waste water treatment plants include measuring the concentration of ammonium and nitrate directly during sludge activation, measuring the am-monium (pH-compensated) load in the inlet to sludge activation, and load-dependent aeration control.</p> <p><b>Measuring layout</b><br /> The compact measuring system contains a sensor and a transmitter. The sensor consists of ion-selective electrodes, a reference electrode, potential matching, a temperature sensor as well as automatic compressed-air cleaning and a pre-amplifier. The sensor is mounted directly on the basin rim with a suitable retaining unit and is immersed directly into the process with the electrodes. Up to three ion-selective electrodes simultaneously measure ammonium, ni-trate and another measured variable, if so required by the customer. They exhibit easily re-placeable membrane caps which are selective for the ion to be measured. A membrane kit with easy-to-use replacement caps is also available as an accessory. The membranes are ro-bust and can be used for up to six months. Thanks to the integrated compressed-air cleaning system, they are kept free from fouling and contamination and are thus always operational.</p> <p><b>Ion-selective measuring principle</b><br /> Potentiometric measurement using ion-selective electrodes is similar to pH measurement: as a result of charged ions "migrating", a potential difference occurs between the measuring elec-trode and the reference electrode. This difference in potential is measured and is proportional to the ion concentration.</p> <p>This new technology extends Endress+Hauser's liquid analysis portfolio. It strength-ens the company's position as a complete provider and offers potential for other parameters and industries.</p> <p><b>About Endress+Hauser Conducta GmbH+Co.
