Magnafloc LT-7989 Alternative — Cationic PAM for Sludge Dewatering
Magnafloc LT-7989 (formerly Ashland, now Solenis) is widely specified in municipal WWTP contracts and industrial sludge systems. Our CPAM High Charge Density grade at 40-50% cationicity and 12-18 million MW is a proven alternative, delivering comparable CST reduction, cake dryness, and centrate quality. We supply this grade to plants in Southeast Asia, India, and the Middle East that previously purchased Magnafloc LT-7989 through distributors at significant cost premiums.

Frequently Asked Questions — Magnafloc LT-7989 Alternative — Cationic PAM for Sludge Dewatering
Does your product meet the same spec as Magnafloc LT-7989?
Yes on all key parameters: molecular weight (12-18M), charge density (40-50%), residual monomer (≤0.05%). We supply a batch COA with every shipment so you can verify against your spec sheet.
Can I switch without telling my client or regulator?
For municipal contracts that specify Magnafloc LT-7989 by name, check your contract terms. Most contracts specify a performance standard (cake dryness, CST), not a brand. If your contract allows equivalent substitution, our COA and jar test report support the change.
I need the product to handle variable sludge (seasonal changes). Can it?
Yes. We recommend keeping 2-3 months of stock to allow dosage adjustment for seasonal sludge variation (higher volatile solids in summer = slightly higher dose needed). This is standard practice regardless of polymer brand.
What is your minimum trial order?
Free sample: 5 kg for lab testing. Trial order: 100 kg (4 × 25 kg bags). Full pallet: 500 kg (20 bags). No commitment beyond what you order.
How do I get the technical data to compare with Magnafloc LT-7989?
WhatsApp us your Magnafloc LT-7989 spec sheet. We send back our TDS side by side. If specs match your needs, we arrange the free sample the same week.
