Norfloc NF1®
Inorganic coagulant based on nanotechnology
Home / Products / Chemistry / Coagulants / Norfloc NF1
New inorganic coagulant that optimizes operation and can replace the traditional metal salts.
Key benefits
- 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
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, Alumichem, 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
- Lower dosage (2-6 ppm) and less chemical sludge
- More stable sludge level, compared to the other 3 lines, in heavy rainfall events
The improved sludge properties when using NF1 mean that sludge levels are kept stably low, even at the maximum hydraulic capacity of the system.
Maximum utilization of the hydraulic capacity reduces the need for bypass to a minimum.
