Two inline, reagent free analysers used in the measurement and control of municipal and industrial treatment plants will be on show at Endress Hauser ’s stand at Ozwater09. The STIP-scan analyser overcomes the costly sampling and maintenance procedures required by cabinet analysers since it operates directly in the process and measures multiple parameters such as COD, TOC and TS. The ISEmax CAS40 inline analyser is placed directly in the wastewater process and continuously measures the concentration of ammonium and nitrate.
Visitors to the Endress+Hauser booth will have the opportunity to evaluate the STIP-scan inline analyser. The STIP-scan analyser/probe is simple to use and is immersed directly in the channel or basin of the wastewater treatment plant and the results indicate conditions directly at the sampling point. The STIP-scan analyser allows the simultaneous measurement of multiple parameters including nitrate, chemical oxygen demand (COD) or total organic carbon (TOC), total solids (TS), sludge volume (SV), sludge index (SI) and spectral absorption coefficient (254 low).
Endress + Hauser’s ISEmax CAS40 inline analyser will be unveiled at Ozwater09. Featuring a transmitter and an ion-selective electrode installed in an immersion assembly, the ISEmax CAS40 inline analyser/probe is placed directly in the wastewater process and continuously measures the concentration of ammonium and nitrate. Industrial and municipal wastewater sludge contains large amounts of toxic ammonium. Purification is accomplished through a nitrification process. A large aeration basin converts the concentration of ammonium to nitrites and nitrates that are eventually extracted. Measurements from the ISEmax CAS40 inline analyser are used to control the powerful, high wattage aeration blowers, ensuring low energy consumption and optimum activation of the sludge.
Endress + Hauser are involved in the measurement and control of municipal and industrial wastewater treatment plants, particularly in the nitrification and denitrification processes within wastewater aeration basins.
