ACRYLAMIDE-FREE FLOCCULANT
Best performance. Acrylamide-free.
The alternative to conventional pFM:
M-FLOC® DAF 800
The addition of synthetic, high molecular weight pFMs (polymer flocculants) to improve sedimentation and dewatering is state of the art in the treatment of wash water from sand and gravel washing. These contain a small amount of acrylamide (unpolymerized due to the manufacturing process) as a residual monomer.
The EU Drinking Water Regulation sets strict limits for acrylamide, which can be easily complied with using conventional pFMs with drinking water approval when used once.
As wash water is recycled several times in practice, with a pFM being added to each cycle, acrylamide can accumulate in the treated water and, if treated recycled water leaks into the groundwater, the specified limit value may be exceeded.
M-FLOC® DAF 800 does not contain acrylamide and scores with the following advantages:
no accumulation of acrylamide in circuit water
free from mineral oil hydrocarbons (MOH)
high PNEC value
easily soluble in water
dissolves very quickly using a simple static mixer
no VOC emissions
stable floc formation
rapid sedimentation
low turbidity
significantly better cleaning performance and lower consumption than starch-based pFM
Our application experts will be happy to advise you on the use of M-FLOC® DAF 800.
Environmental compatibility of M-FLOC® DAF 800 compared to conventional pFM
In the absence of limit values in the EU Drinking Water Regulation, the PNEC value (predicted no effort concentration) is used.
This refers to the predicted concentration of a substance that is generally hazardous to the environment, up to which there are no effects on the environment:
| PNEC value [mg/L] | fresh water | sea water | wastewater treatment plant |
| acrylamide | 0.032 | 0.002 | 0.2 |
| monomer M-FLOC® DAF 800 | 2 | 0.2 | 713 |
| factor | 62.5 | 100 | 3565 |
