ChinaPAM is a factory-direct flocculant manufacturer and water treatment polymer supplier in China. Our core product is polyacrylamide (PAM) polymer flocculant in anionic, cationic, and nonionic grades, supported by polyaluminium chloride (PAC), polyDADMAC, and polyamine coagulants. For buyers comparing flocculant and polymer flocculant suppliers in China, this page is the starting point: pick the flocculant family below, review the verified buyer facts, then move to the grade-level specification pages.
Not sure whether you need a coagulant, a polymer flocculant, or both? Send your application, water chemistry, and solids data through Request Quote and we will recommend a coagulant-plus-flocculant program before pricing, or start with the polyacrylamide manufacturer overview.
Polyacrylamide (PAM)
Polymer flocculantRole: Organic polymer flocculant
Charge: Anionic, cationic, or nonionic
Best for: Municipal and industrial wastewater, sludge dewatering, mineral tailings, raw-water clarification, and enhanced oil recovery. The primary high-molecular-weight flocculant for bridging suspended solids.
Choose a polymer flocculant when you need strong bridging and fast settling or dewatering of suspended and organic solids.

CoagulantRole: Inorganic coagulant
Charge: Cationic (metal salt)
Best for: Primary coagulation and charge neutralization ahead of polymer flocculation. Common in drinking-water and municipal treatment as a coagulant paired with PAM.
Choose a coagulant to destabilize fine colloids first, then dose a polymer flocculant to build settleable flocs. Ask us for PAC availability by grade.

CoagulantRole: Organic coagulant
Charge: Cationic (low MW)
Best for: Color and turbidity removal, primary coagulant duty, and cationic demand where a low-molecular-weight organic coagulant works better than a metal salt.
Choose an organic coagulant for color-body and charge-demand loads. Contact us for polyDADMAC and polyamine grade availability.

SpecialtyRole: Application-matched grades
Charge: Application-specific
Best for: Drilling-fluid PHPA, food-processing wastewater grade, and other flocculant formulations matched to a specific process or compliance profile.
Choose a specialty flocculant when the process needs viscosity control, salinity tolerance, or a specific compliance profile.

Buying Flocculant Direct From the Manufacturer
Factory-direct pricing
Ordering from the manufacturing base rather than a trading layer keeps flocculant grade selection, batch documentation, and pricing in one place.
Coagulant + flocculant matching
We match the coagulant and the polymer flocculant charge and molecular weight to your process before quoting, instead of quoting one generic grade.
Sample before bulk
Free samples let you run jar tests on your own water or sludge before committing to a bulk flocculant order.
Export documentation
Grade-specific TDS, batch COA, and SDS support customs clearance and internal QA review. Compare the supplier profile or the water treatment chemicals supplier page.
Frequently Asked Questions
What is a flocculant and how is it different from a coagulant?
A flocculant is a chemical that binds destabilized fine particles into larger flocs that settle or dewater quickly. A coagulant comes first: it neutralizes the surface charge on colloidal particles so they can come together. In practice a coagulant (like polyaluminium chloride or polyDADMAC) is dosed first, then a polymer flocculant (polyacrylamide) bridges the neutralized particles into settleable flocs. Many water treatment programs use both.
What types of flocculant do you supply as a manufacturer in China?
Our core flocculant is polyacrylamide (PAM) in anionic (APAM), cationic (CPAM), and nonionic (NPAM) grades, plus oilfield PHPA and food-processing grades. We also supply and source coagulants including polyaluminium chloride (PAC), polyDADMAC, and polyamine to pair with the polymer flocculant. Send your application and water chemistry and we will recommend a coagulant-plus-flocculant program before pricing.
Which flocculant is best for sludge dewatering?
Sludge dewatering almost always uses a cationic polyacrylamide (CPAM) flocculant, because most organic sludge carries a negative surface charge that cationic polymer neutralizes and bridges. Charge density and molecular weight are matched to the sludge type and the dewatering equipment (belt press, centrifuge, or filter press). Typical dosing is 3-8 kg of polymer per ton of dry solids, confirmed by jar and lab testing.
How do I compare polymer flocculant suppliers in China?
Compare manufacturer-backed facts first: MOQ 500 kg, free sample support, T/T or L/C payment scope, 25 kg export packaging, grade-specific TDS, batch COA, SDS, and whether the supplier matches the flocculant charge and molecular weight to your water or sludge before quoting. A useful flocculant quote should match application and charge type before price comparison, not quote a single generic grade.
What is the MOQ, lead time, and packaging for flocculant export orders?
The standard trial-order MOQ is 500 kg. Common-grade lead time is usually 7-10 days after order confirmation. Standard export packaging is 25 kg kraft paper bags with a plastic liner or 25 kg PE bags. Free samples are available before bulk confirmation so jar testing can happen first.
What is the typical flocculant dosage for water treatment?
Polymer flocculant dosing depends on application and grade: municipal wastewater 1-3 mg/L, raw-water clarification 0.5-2 mg/L, sludge dewatering 3-8 kg per ton of dry solids, and mining tailings 20-50 g per ton of dry solids. Coagulant dosing (PAC, polyDADMAC) is separate and set by jar test. Always run jar tests because dosage varies with water chemistry and suspended solids.
