Coagulation control webinar

October 21 @ 1:00 pm - 4:00 pm


Effective coagulation control is a vital step in ensuring the safety of potable water. Most natural waters sources will contain dissolved and suspended solids and failure to remove these contaminants can result in the spread of bacteria, algae and viruses. Cryptosporidium is a particularly nasty parasite that can cause severe diarrhoea illness and can even be fatal. It is resistant to chlorine and many other filtering techniques, and can be found in any surface water source, making efficient and effective coagulation control vital step in the process to ensure potability.

Removal of these particles is achieved by coagulation and flocculation. Coagulation is essential for good clarification and filtration performance in removing organic compounds.

This workshop explored current and new methods/technologies used for optimising and automatically controlling the coagulation process providing the water companies with the reassurance that their coagulation process is being correctly controlled.

A variety of measurements and methods are used to try to attain this goal in continuous automatic operation and these were reviewed along with the practical experience of users.

Chaired by: Mike Sparrey, ABB
