New: Measurement of media with high ammonium load
When thickening or dehydrating wastewater treatment sludge, the so-called centrate water is generated. This water has an especially high amonium content. The centrate water is not drained but rerouted into the wastewater circuit of the system or directly broken down into elementary nitrogen (deammonification). In both cases, the determination of the NH4 freight is very important for an optimal process run. High NH4 concentrations of up to 2000 mg/l can now be determined directly in the medium by means of the Varion®Plus 700 IQ, in centrate water as well as in process waters!
