FLOPAM FO 4190 VHM Equivalent: Low-Charge Cationic PAM Supply Route
ChinaPAM supplies low-charge cationic PAM powder with C8008 as the starting same-ion-type route for FLOPAM FO 4190 VHM duty. C8008 sits at Medium molecular weight on our scale while SNF historically lists FO 4190 VHM at Ultra High molecular weight, so the supply trial checks the effect of that chain-length difference on your feed and equipment. Ask for current pricing or sample options using the grade name, a bag-label photo or your purchasing requirement; process details can follow.

The exact VHM entry
SNF SAS Catalogue 2007 Poudres, page 4, lists FO 4190 VHM as cationic powder with Low charge and Ultra High molecular weight. The indicative Brookfield readings are 680 / 340 / 160 cps at 5 / 2.5 / 1 g/L. Recommended make-up is 3 g/L, maximum 5 g/L; dissolution is 240 minutes in deionized water at 5 g/L and 25 degrees C. These historical averages are not current contractual specifications, and suppliers do not share a calibrated descriptor scale.
FO 4190 SH is a different entry on page 7: Low charge, High molecular weight, 280 / 130 / 45 cps and 90-minute dissolution under the same stated dissolution conditions. VHM is a real suffix, not an alternative spelling of SEP or SH.
Our route and its limits
C8008 is the only Low-charge cationic powder in the current 26-grade ChinaPAM table. Selecting our highest molecular-weight cationic grade instead would also change the charge band; it would not resolve both selection questions automatically. There is no established second route for this page.
Prepare our candidate at 1-3 g/L, maximum 5 g/L, with dissolution within 60 minutes at working concentration. Those are our instructions, not a replacement for the incumbent's 240-minute reference. Make-up concentration and treatment dose are separate quantities.
Two changeover checks
Maturation: retaining an SH-based 90-minute release schedule for VHM can leave the incumbent solution incompletely prepared. Verify residual particles and maturation at your actual water temperature and concentration before judging flocculation performance.
Charge versus molecular-weight selection: do not choose a higher-charge powder solely to obtain a higher molecular-weight label. Compare C8008 with the incumbent on the same feed, measuring delivered polymer dose, clarification and the relevant dewatering endpoint. For a sludge duty, include filtrate or centrate clarity and cake handling rather than settling appearance alone. These are trial criteria, not claims that C8008 has already matched FO 4190 VHM.
Discuss a supply trial
Send the full grade label, current make-up and maturation settings, dosing equipment, treatment objective and monthly quantity. We will discuss C8008, sample arrangements and documents applicable to your order.
Dosage Guide
Prepare our powder at 1-3 g/L, maximum 5 g/L, with dissolution within 60 minutes at the working concentration. Make-up concentration is different from the treatment dose. Establish the dose on your actual feed and verify measured polymer delivery.
