Protea was asked to supply a high level ammonia (NH3) measurement system for a waste water treatment plant. The reflux drums at the inlet to two ammonia stripping towers needed to be measured continuously.
Protea designed a solution based around our Solus TDLAS analyser platform and a high level dilution system. The Solus analyser was configured for NH3 measurements in the range 0-500ppm. A dilution system incorporating special dilution probe and 19" control panel was installed before the analyser. This gave a dilution level of 600:1, enabling the NH3 analyser to measure in the range 0-30% Volume.
