Alkalinity monitors are key to ensuring effective pH control in wastewater treatment when using coagulants such as ferric.

Online alkalinity measurement in wastewater is achieved via titration. Alkalinity is reported in units of mg/l CaCO3 and measured by titrating a sample with an acid until it reaches a defined pH end point. Titrating a known volume of the sample with dilute acid of a given strength to pH 4.3 is the standard approach. Titrating until this pH ensures all the species in the sample contributing to alkalinity have been neutralised.

At PMA we supply acids for titration as well as alkalinity standards. If you don’t see what you need in our catalogue please get in touch.
