FLOPAM EM 840 CT Equivalent — Cationic PAM Powder-Conversion Screening

SNF Inc.'s technical data sheet for the exact EM 840 CT grade describes a milky viscous liquid, with average non-volatile solids of 44–51%. Every grade in the current ChinaPAM range is a powder. So before any grade number is discussed, this enquiry is a shape conversion.

That matters commercially, not just technically. A liquid at roughly half solids and a powder cannot be compared tonne for tonne, cannot be dosed on as-supplied weight, and do not use the same preparation equipment. If your site has only liquid or emulsion handling today, the honest first question is whether it can wet, dissolve, age and meter a powder at all — and if it cannot, no grade recommendation on this page is worth anything until that is resolved.

With that stated: ChinaPAM can quote a cationic powder-conversion screening route for EM 840 CT duty, starting from the very-high-charge, very-high-molecular-weight bracket, once intake is complete. This does not claim the same physical form and does not claim exact equivalence. After intake, ChinaPAM can discuss a quotation and the applicable route documents. Branded stock, current incumbent availability, fixed price or lead time, sample dispatch and model-specific self-manufacture are not stated from this source.

Require the full FLOPAM EM 840 CT name, with the CT suffix, plus your current label and datasheet. The suffix is the identity and it is not optional here.

EM 840 HIB, EM440, EM630 and EM640 CT are not the same identity and are not accepted as substitutes for it. These are genuinely different products: the ChinaPAM page for EM 840 HIB exists separately and rests on its own source documents, and EM630 is anionic in its current owner's own listing. Sharing the 840 sequence number with HIB does not make the two one product, and an EM 840 HIB enquiry belongs on the HIB page rather than this one.

The practical consequence of merging them is specific: you can end up with the wrong ionic type, the wrong form, the wrong band, the wrong storage requirement or the wrong purchasing route. Send the complete label as printed and each model stays in its own evidence family.

All three rows come from SNF Inc.'s technical data sheet for the exact CT grade, PDF page 1. They describe the incumbent, not any ChinaPAM grade.

Both come out of the specific evidence held for this model, not from general advice.

ChinaPAM reviewed its complete current range — all twenty-six grades — against this duty. Exactly two rows match cationic plus very high charge plus very high molecular weight: C8055 and C8006. Both are powders.

The range record does not distinguish those two any further on these fields, which means the present evidence does not support calling one of them the primary and the other the backup. So they stay an unranked two-grade powder-conversion bracket. Current grade documents and same-duty testing come first, and the trial ranks them — the trial does not confirm a winner that was picked in advance.

What is known about the incumbent: cationic, milky viscous liquid, very high charge and molecular weight, 44–51% non-volatile solids. What the ChinaPAM route offers: cationic powder candidates at the very-high and very-high bands. What is unknown: cross-vendor band tolerance and actual performance on your duty. What is required: an active-polymer conversion and an equipment conversion test.

Useful intake, in order: the complete label and current datasheet and safety data sheet; the duty and the equipment you run; feed or sludge solids; pH; conductivity; your incumbent as-supplied dose; the solution concentration you make down to; your storage limits; monthly volume; destination; and the acceptance metrics the duty is judged by.

Equipment comes next, and on this enquiry it is not a formality. Audit whether the site has liquid and emulsion handling only, or can genuinely wet, dissolve, age and meter a powder. Compare pumps, tank volume, water quality and transfer shear against the incumbent setup, and note that the incumbent datasheet gives a one-day solution-use window — your powder solution window has to be planned against the same operating rhythm.

ChinaPAM powder preparation runs at a 1–3 g/L recommended window, 5 g/L maximum, and no longer than 60 minutes at working concentration. Preparation concentration is not process dosage.

Candidates are prepared under their own current grade instructions. The trial then compares them against the incumbent on an equal active-polymer dose, using identical feed, mixing energy, contact time and measurement windows. Start with the unranked C8055 and C8006 pair and do not predeclare a winner. Repeat the leading candidate under adverse conditions.

Record, under the same conditions: the treatment result that actually matters to you, active dose, clarity, settling or dewatering response, floc shear resistance, solution preparation time, pumpability, storage footprint, operator workload and cost per treated unit. The last four are where a liquid-to-powder conversion is usually won or lost, so they are not optional lines on the sheet.

Go/no-go: proceed only if the complete CT identity is confirmed, the facility can support the selected powder route, current candidate documents pass review, and the same-duty trial meets the agreed metrics. Otherwise the enquiry stays open for further sourcing and no equivalence is asserted. Current price, stock status, lead time, applicable TDS and sample arrangements are confirmed in the quotation. Batch-specific COA terms are confirmed with the shipment.
