FLOPAM FO 4190 / 4240 / 4290 Equivalent — Low-Charge Cationic Polyacrylamide
SNF publishes FLOPAM FO 4190, FO 4240 and FO 4290 in the same technical data sheet, and all three carry the same profile there: low charge density at standard molecular weight. In the FO naming convention the second and third digits track cationic charge, so the three numbers step upward, but they step within one published band rather than across bands. That is why one grade on our side covers all three for most duties, and why we separate them on the trial result instead of on the number. Our matching product is a medium charge density, medium molecular weight cationic polyacrylamide powder on our own scale. The two houses publish on different scales, so we set the grade by capillary suction time or jar test on your own sludge rather than by converting descriptors, and we ship a free trial quantity for that purpose.

Dosage Guide
Cationic polymer demand for dewatering is set by the sludge, not by the polymer datasheet. Establish it by CST or jar test and use your current FO 4190, 4240 or 4290 active dose rate as the starting reference. Make up at 0.2 to 0.5 percent and allow full ageing before dosing.
Frequently Asked Questions — FLOPAM FO 4190 / 4240 / 4290 Equivalent — Low-Charge Cationic Polyacrylamide
FO 4190, FO 4240, FO 4290 — why does one grade of yours cover all three?
Because SNF publishes all three at the same charge and molecular weight profile in the same data sheet: low charge, standard molecular weight. The numbers step upward in cationicity but stay inside one published band. For most dewatering and retention duties a single grade on our side answers the band, and where a plant sits at the edge of it the trial result decides, not the number.
I run FO 4290 SH. Does this page apply to me?
Only as a starting point. The suffix moves you up the molecular weight ladder and in the cationic FO range that can also move the charge band, which puts you on a different grade on our side. Send the full grade string as it appears on your delivery note and we will answer against the right band rather than the bare number.
My current supply is a distributor drum with no grade sheet. Can you still match it?
Yes, but by test rather than by paperwork. Send roughly 500 g of the product you use now together with a sludge sample and we run a side-by-side CST and jar test, then quote against the grade that wins. This is the honest route when the label has been through a repacking step.
How do I compare your grade against my current polymer fairly?
Run a capillary suction time test or jar test on the same sludge sample on the same day, matched on active polymer dose rather than on product dose, and record cake solids and filtrate clarity together. Matching on product weight alone hides differences in active content.
Is your product a licensed copy of the FO grades?
No. It is an independently manufactured cationic polyacrylamide positioned against the published FO profiles, not a licensed or reverse-engineered copy. FLOPAM is a trademark of SNF and we make no claim of affiliation. Confirm performance by CST or jar test on your own sludge before changing supply.
