chapter 21: page example


Continuous and automatic treatment process regulation involves the use of analog measurements and of detection values that provides TOR (tout ou rien in French = all or nothing) data. It is very important that we differentiate between these two information modes:

Commonly used measurements and detection systems apply to liquids regardless of their loading (including liquid sludge), liquid reagents, paste-like or dry products (dewatered sludge, dried sludge, powder, ash...), and to gases (process air, foul air, biogas, water vapor...) within the context of plant operation and safety and of the quality of the water produced by the plant.

The first part of this section consists of a list of the principle of measurements used in the water industry; the second provides relevant application examples given by treatment area.
