FLOPAM AN PWG and SEP Grades — Polyacrylamide Selection Route with Document Check
ChinaPAM answers FLOPAM PWG and SEP enquiries with a polyacrylamide selection route: we identify the base grade and ion type, name a nonionic or anionic screening lane, and confirm which market and project documents your drinking-water duty requires before the quotation is finalised. Send the full grade, the duty and the documents your authority asks for.
Supply Route Comparison
Published reference data and the ChinaPAM route for SNF FLOPAM AN PWG and SEP grades
Competitor figures are from SNF, FLOPAM AN PWG & SEP (drinking water production) table in the FLOPAM Catalogue 2007 (PDF pages 50–51). SNF states these data are given for information only and do not constitute a specification. They are historical indicative figures under SNF test conditions, not ChinaPAM specifications and not evidence of current SNF availability.

Sixteen Exact Columns, Eight Base Grades
SNF pp.50–51 place every base grade twice, once with PWG and once with SEP, and publish the same values for both. The practical reading is simple: identify the base grade and its ion type, then keep the full suffix on your documents for traceability.
Three published facts in that table do most of the selection work. All sixteen columns are listed Very High molecular weight, so the suffix and the base grade are not telling you anything about a molecular-weight step. Make-up and dissolution split the table in two: FA 920 and AH 912 are listed at 5 g/L recommended, 10 g/L maximum, with 180 and 150 minutes to dissolve, while every AN column is listed at 3 g/L recommended, 5 g/L maximum, and 90 minutes. And the approximate Brookfield viscosity at 5 g/L does not simply climb with charge — it runs 100, 350, 450, 800, 1200, 1395, 1715 up to AN 934, then falls back to 1600 for the higher-charge AN 956.
| Base grade (PWG + SEP) | Charge density | Rec. / max make-up (g/L) | Dissolution @ 5 g/L, 25°C (min) | ChinaPAM starting direction |
|---|---|---|---|---|
| FA 920 | Non-ionic | 5 / 10 | 180 | Nonionic lane (1003) |
| AH 912 | Very low | 5 / 10 | 150 | Very-low-charge anionic lane (1082) |
| AN 905 | Very low | 3 / 5 | 90 | Very-low-charge anionic lane |
| AN 910 | Low | 3 / 5 | 90 | Low-charge anionic lane |
| AN 913 | Low | 3 / 5 | 90 | Low-charge anionic lane |
| AN 923 | Medium | 3 / 5 | 90 | Medium-charge anionic lane |
| AN 934 | Medium | 3 / 5 | 90 | Medium-charge anionic lane |
| AN 956 | High | 3 / 5 | 90 | Higher-charge anionic lane |
Documents First: What the Suffix Cannot Tell You
The table heading says drinking water production. That describes SNF’s product positioning in 2007, not the status of any ChinaPAM grade. Requirements differ by country and project, so we ask which documents your authority or client specifies and confirm what can be supplied before the quotation is finalised.
A food-grade note on another product line is not a drinking-water document and is not offered as one.
Two Ways a PWG/SEP Changeover Goes Wrong
Treating the suffix as a compliance proof. A PWG or SEP label does not make a replacement grade acceptable for drinking-water use. The required market and project documents must be confirmed first.
Choosing by the shared application heading, or by the neighbouring column. FA 920 PWG and AH 912 PWG sit side by side on p.50 under one heading, but SNF lists FA 920 as non-ionic and AH 912 as very low charge — two different ion types, and two different ChinaPAM lanes. The published make-up and dissolution figures for those two columns (5 g/L, 180 and 150 minutes) also differ from every AN column (3 g/L, 90 minutes), so a preparation routine carried over from the wrong column can leave the polymer under-hydrated. Confirm the full grade and the water-treatment duty before any lane is quoted.
Selection and Jar-Test Plan
Once the base grade and document requirement are clear, the ChinaPAM screening grade is made up at your working concentration and compared against the current PWG or SEP grade on the same raw water, at stepped doses, with your clarity and settling targets as the pass mark.
What to Send for a Quotation
The full grade, quantity and destination are enough to start. These details sharpen the plan:
| Input | Why it matters |
|---|---|
| Full grade with suffix, or a bag-label photo | Fixes base grade and ion type |
| Documents required by your authority or client | Checked before the quotation is finalised |
| Water-treatment duty, current dose and target | Baseline and pass mark for the jar test |
| Expected volume and destination | Pricing, packaging and lead time in the quotation |
Documents and Delivery
The applicable TDS is confirmed together with the selected ChinaPAM grade, and a batch COA is tied to the confirmed shipment. Any further documents your drinking-water authority or client specifies are treated as a separate confirmation, not as something the PWG or SEP suffix already answers. Packaging and lead time are confirmed in the quotation for your volume and destination.
Dosage Guide
Use the current PWG or SEP grade dose as the reference. Prepare the ChinaPAM screening grade at your working concentration, allow full hydration, and compare stepped doses on the same raw water.
Frequently Asked Questions — FLOPAM AN PWG and SEP Grades — Polyacrylamide Selection Route with Document Check
Is a ChinaPAM grade approved for drinking water because it replaces a PWG or SEP grade?
No. The PWG or SEP suffix is SNF’s label and proves nothing about a ChinaPAM grade. Tell us which market and project documents your drinking-water duty requires, and we confirm what can be provided before the quotation is finalised.
What do PWG and SEP mean?
The 2007 catalogue does not define them, and we do not guess. Each PWG and SEP pair carries identical published values for its base grade, so the base grade is what drives selection.
Can I pick any grade from the drinking water table?
No. The table puts two non-ionic columns (FA 920 PWG and SEP) next to fourteen anionic columns running from very low charge (AH 912, AN 905) to high charge (AN 956). Choosing by the shared heading alone can put the wrong ion type or charge into your process.
Which ChinaPAM lane starts for FA 920 or AH 912 PWG/SEP?
They are different lanes. FA 920 PWG and SEP are listed non-ionic, so the screening start is our nonionic powder grade 1003. AH 912 PWG and SEP are listed very low charge — anionic, not non-ionic — so the start is our very-low-charge anionic grade 1082, the same lane our FLOPAM AH 912 SH page already uses. A jar test on your water selects the final grade.
Which documents come with the supply?
The TDS for the selected ChinaPAM grade and a batch COA tied to the confirmed shipment. Any additional drinking-water documents your authority requires are confirmed case by case before quotation is finalised.
