Norfloc NF1
New inorganic coagulant that optimizes operation and can replace the traditional metal salts
What is Norfloc NF1
Benefits of Norfloc NF1
Improved sludge properties and faster precipitation (lower SVI)
Increased hydraulic capacity
More stable operation, even during rain!
Fewer filamentous bacteria, and thus less floating sludge and foam
Lower dosage (2-6 ppm) and less chemical sludge
Thicker sludge in clarification and less polymer consumption for dewatering

The main ingredients of the product:
Fe0 , 1-60 nM (metal particles)
Other ingredients:
Ascorbic Acid (Vitamin C)
Folic acid (to lower the pH of the product)
Results with Norfloc NF1
Damhusåen RA is a major wastewater treatment plant in Copenhagen. For a longer period, they had great challenges with the sludge properties of the treatment plant, which at times has caused the system to be difficult to stabilize and control.
In April 2020, NORLEX, in collaboration with BIOFOS, started a full-scale trial on one of the 4 lines at the Damhusåen, where iron chloride has been replaced with Norfloc NF1.
After just 3 weeks of operation with Norfloc NF1, the following is observed:
Better / faster precipitation (reduced SVI)
Higher SS in sludge from post-clarification to biology
Fewer filamentous bacteria (TI=3 til TI=2,5)
Less foam and floating sludge on the aeration tanks
More stable sludge level, compared to the other 3 lines, in heavy rainfall events
