How can we control biofilm growth in drinking water pipeline without increasing disinfectant dosing as WQ standards and not to end up with disinfectant byproducts due to excess disinfectant?

Disinfectants obviously controls biofilm growth. But increasing dosing pose ...

Magnetic polarization treatments reduces biofilm in pipes

Hello,

We have experienced very good results with our magnetic polarization treatment in pipes, primarly in internal networks like hospitals, but more recently in drinking water pipeline.

Our treatement is originally designed for reducing scaling via cristalization changes from calcite to aragonite (like talcum powder). But as we use the most powerful materials available (rare earth), we also noticed :

* permanent bacteria abatement in the device
* biofilm destabilization in distributed water. This is due to a slight change of water surface tension which makes conditions unfavorable to biofilm
 
The time scale is 3-4 months to measure biofilm decrease, which we do with ATP-Metry. We have installed devices on 'small to medium' drinking water networks, i.e. several tens of km / linear distribution (non looped)
 
Don't hesistate to contact me if this seems relevant to you
