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?


In order to control becoming better the proliferation of biofilm in the pipes we need to consider the following points:
- Chois the lining of the pipes.
- Optimize the profile volumes.
- Ensure adequate flushing of the pipelines during commissioning
- Master water leaks from the outside to the inside and vice versa.
- Optimize the contact time water / disinfectant
- Ensure adequate disinfectant residual rate (it must not exceed the rate allowed by the standard)

Biofilm can be controlled by splitting the TDS in water with an anode and cathode. We have access to the patent and prototype and this was fully tested at the Biofilm lab in the USA. The process does not add chemicals or generate disinfection by-products.

Hi Lisa,

Is it similar to Cathodic corrosion protection for steel pipes? Could you please tell me more about the method? How does this method work for the pipeline which already accumulated thick biofilm?
