Conclusion

Conclusions:

29

• Wide range of use

• Superior effectiveness to all other biosourced flocculants

• Technical-economical performance compared to polyacrylamides

• Excellent resistance with cold water to be clarified (down to 2°C)

• Compatibility in the flocculation phase with Powdered Activated Carbon

• No biofouling impact on a downstream membrane separation (MF or UF)

• Residual Biodegradable Dissolved Organic Carbon (BDOC) is negligible in the treated water

• Complies with regulators’ standards

• No THM/HAA* impact on the treated water
