a |
These applications use an
anionic or non-ionic, emulsion- or powder-form, flocculant-grade polymer
along with the coagulant-grade product. |
|
b |
These products are available in GRAS versions. |
|
c |
These products are FDA approved under 21CFR173.5 |
|
d |
For centrifuge applications, emulsions can be custom-blended to improve floc stability and drainage. Contact one of our resale managers for
assistance. |
|
e |
Steel mill process and waste waters are typically cationic; so anionic
or non-ionic polymers with pH adjustments will usually provide good
results. |
| |
Cationic polymers should only be needed in rare instances. |
