Activated Sludge Process Optimisation

Activated Sludge Process Optimisation

A trial conducted by Xylem Analytics using the WTW VARiON Ammonia ISE against a competitor's wet chemistry analyser on the inlet to a
major ASP on a flagship works in the UK revealed just how far the ISE technology has come through the intensive investment in R&D that Xylem has made.
A sample of 6 weeks of data is presented across the plots featured within the application note.
Two ISE sensors were installed: one with additional air cleaning and one "straight out of the box". These sensors were calibrated to the liquor matrix during the initial commissioning and then remained untouched for the remainder of the trial.
See the results of the trial in our Application Note.
