PRODUCT INTRODUCTION
Modified Polyacrylamide (PAM) is a high-molecular water-soluble polymer obtained by chemical modification of polyacrylamide backbone. Through cationic, anionic, nonionic or amphoteric modification, it gains adjustable charge density, molecular weight and adsorption selectivity, widely used for flocculation, sedimentation, dewatering, dispersion and viscosity boosting in water treatment and industrial separation processes.
This modified PAM series covers sewage sludge dewatering, mining mineral settling, oilfield water blocking and profile control, papermaking retention & drainage, textile printing thickening, and construction slurry stabilization. Compared with ordinary PAM, modified grades show stronger anti-salinity, better adaptability to complex water quality and higher flocculation efficiency under variable pH conditions.
The product is supplied as white powder, granule and emulsion. It dissolves slowly in cold water without forming insoluble lumps when prepared correctly. It does not pollute water systems after proper dosage control and meets the requirements of industrial environmental protection discharge standards. Different modified structures are customized to match high-salinity wastewater, oily sewage and fine particle suspension systems.
Every batch of Modified Polyacrylamide is inspected for molecular weight, charge degree, dissolution rate and flocculation performance before delivery. Complete export documents including COA, TDS and SDS(MSDS) are provided for customs clearance and quality tracing. Our technical team can select suitable ion type and molecular weight grade based on your water quality index, solid content and separation target.

USAGE NOTES
Dosage Control:
Overdose will increase viscosity, make flocs loose and raise processing cost. Start from low dosage and increase step by step according to jar test results.

Dissolving Operation:
Slowly spread Modified PAM powder into stirred cold water, avoid dumping directly to prevent agglomeration. Stir speed controlled at 60–120 rpm, fully dissolve before dosing.

Compatibility Check:
Do not mix cationic and anionic PAM directly; precipitation and failure will occur. Test compatibility with PAC, ferric salt and other flocculants before mass running. EU export needs REACH SVHC check.

Process Condition:
High salinity and extreme pH reduce flocculation effect; choose anti-salt amphoteric grade for complex wastewater. Keep dosing point with enough mixing reaction distance.

COMMON PROBLEMS IN DOWNSTREAM PRODUCTION
Slow Settlement, Small and Loose Flocs
Wrong ion type, insufficient molecular weight or too low dosage leads to weak flocculation.
Solution: Re-test water sample, switch to matching grade, adjust dosage and cooperate with inorganic coagulant.
Sludge Cake Moisture Remains High
Unsuitable cationicity, uneven mixing or filter press parameters not matched.
Solution: Adjust cationic degree, optimize dilution concentration and reaction time before filter pressing.
PAM Caking and Hard Lump During Dissolving
Rapid pouring of powder without dispersion, stirring speed unreasonable.
Solution: Sprinkle powder slowly on vortex surface, control stirring speed, avoid high-temperature water dissolving.
Floc Disappears after Adding PAM
Anionic and cationic agents mixed together, or excess coagulant breaks floc structure.
Solution: Separate dosing pipelines, reset dosing sequence and reduce front coagulant dosage.
Poor Effect in High-salinity Wastewater
Ordinary PAM is sensitive to salt ions, polymer chain curls and loses adsorption capacity.
Solution: Use anti-salt amphoteric modified PAM grade PAM-AM400.
Unstable Viscosity for Oilfield / Drilling Mud
Degradation caused by high temperature, shear or bacterial erosion.
Solution: Add stabilizer and biocide, select high-temperature resistant modified oilfield grade.
Customs Inspection Due to Document Error
Wrong HS, CAS or SDS description causes detention.
Solution: Confirm destination country rules in advance. Standard export data: HS 3824.9999, CAS 9003-05-8, non-hazardous. We supply full consistent documents.
Batch Performance Deviation
Different dissolving concentration, water temperature and raw water fluctuation cause unstable results.
Solution: Standardize dissolving and dosing process, inspect each incoming batch by jar test.
