HAA5 Formation Potential

Online automatic coagulation control systems utilising UV-Vis spectroscopy and can be configured to output a HAA5 formation potential parameter based on NOM characterisation of the raw water entering the drinking water treatment works.

By measuring formation potential in the raw water you can identify the level of the source risk, and  it tells you how much treatment you need. By also measuring on the filtered water before chlorination you can show in real time what your removal of the THM and HAA pre-cursors are and you can optimise the plant to remove these and not just generic NOM.
