Anionic Polyacrylamide APAM 0.1-0.5% Working Solution for Secondary Effluent Suspended Solids Polishing CAS 9003-05-8 ISO 14001 Manufacturer 750kg Net Big Bag
Product IntroductionBLUFLOC APAM Grade-Selection Family
Secondary Effluent Suspended Solids Polishing buyers are usually not looking for a generic bag of PAM. They need a polymer program that fits secondary effluent with light biological flocs, pin floc and low-to-moderate residual TSS. BLUFLOC APAM is positioned on this page as a grade-selection family for that specific operating problem.
In the treatment train, BLUFLOC APAM captures dispersed fine solids into flocs suitable for clarification, flotation or filtration pretreatment. Because water chemistry, particle charge, shear and separator design all change the result, Bluwat recommends laboratory screening followed by a controlled plant trial rather than publishing a universal dosage or guaranteed removal rate.
Application ChallengesWhat Operators Are Solving For
How BLUFLOC APAM WorksBridging Mechanism
After particles have been destabilized when required, hydrated anionic polyacrylamide chains adsorb on more than one particle. This bridging mechanism increases the effective floc size and changes how the solids settle, float or drain. The selected polymer captures dispersed fine solids into flocs suitable for clarification, flotation or filtration pretreatment. Polymer selection must balance charge interaction, molecular weight, mixing energy and the target separator.
Treatment boundary: Polymer polishing addresses suspended solids. It does not disinfect the effluent or replace membrane, nutrient-removal or oxidation processes.
Recommended Grade and Selection GuidanceScreen Before You Specify
Screen low, medium and higher anionic-degree grades across the 5-100% family range together with molecular-weight options in the 5-25 million range. The headline parameter is a procurement filter, while the jar test determines the practical grade.

TDS note: Values describe the BLUFLOC powder family. The supplied TDS labels the degree row as 'Anionic Degree' across all columns; this document uses 'Charge Degree' for CPAM and 'Ionic Degree' for NPAM for clearer publishing. Confirm the final commercial grade by sample testing.
Application ProcessFrom Effluent Sampling to Filter Run Evaluation
- Sample across normal and upset secondary-clarifier conditions.
- Screen low polymer doses and several APAM charge levels.
- Add after any coagulant or phosphorus-precipitation stage.
- Use gentle flocculation before settling, DAF or filtration.
- Evaluate filter run length or reuse-water quality during scale-up.
Solution Preparation and DosingMake-Down Best Practice
- Fill the make-down tank with clean water and start agitation in the 200-400 rpm TDS range.
- Add the powder slowly and evenly to avoid fish-eyes or lumps; do not dump a full bag into one point.
- Prepare a 0.1-0.5% working solution and allow about one hour for complete dissolution, subject to water quality and temperature.
- Avoid high-speed mixing after hydration because excessive shear can reduce polymer-chain performance.
- Meter the dilute solution into the selected feed point. Keep concentrated PAM separate from coagulants unless compatibility is proven.
Trial Evaluation ChecklistWhat to Measure During Screening
- Track polished effluent TSS.
- Track turbidity.
- Track filter differential pressure or run time.
- Track residual polymer control.
- Record the untreated control, chemical sequence, mixing energy, water temperature and observations at each dose.
Product Advantages for ProcurementWhy Buyers Shortlist BLUFLOC
- Application-led grade screening for secondary effluent suspended solids polishing instead of one-grade-fits-all selling.
- Powder family covers anionic, cationic and nonionic options for comparative testing.
- TDS-grounded solid content, particle size, residual monomer, solution concentration, storage and shelf-life data.
- 25 kg bags and 750 kg net big bags support trials, distributor inventory and bulk plant consumption.
- Laboratory and technical selection support for sample screening and scale-up planning.
Packaging, Storage and HandlingListing Pack and Bulk Options
Listing pack: 750 kg net big bag. The family TDS states kraft paper or PE bags with inner plastic bags, 25 kg per bag, or 750 kg net big bags.

Frequently Asked QuestionsTechnical and Procurement
Is APAM the correct grade for secondary effluent suspended solids polishing?
It is a TDS-supported screening candidate, not a fixed prescription. Test several molecular-weight and charge options with representative water or sludge, then confirm the best grade in a plant trial.
What starting dosage should be used?
No universal plant dosage is stated. Begin with a laboratory dose series, include an untreated control, and optimize the total treatment program against clarity, separation rate, sludge behavior and cost.
How should the powder be dissolved?
Prepare a 0.1-0.5% solution by adding the powder slowly into agitated water. The TDS indicates about one hour for complete dissolution and 200-400 rpm agitation. Avoid high shear and undissolved lumps.
Can BLUFLOC PAM replace the primary coagulant or reaction chemistry?
Not automatically. Polymer polishing addresses suspended solids. It does not disinfect the effluent or replace membrane, nutrient-removal or oxidation processes. In many applications PAM is added after coagulation, precipitation, neutralization or emulsion breaking.
What information should be sent for grade selection?
Send the application, treatment flow diagram, pH, conductivity, TSS or sludge solids, current chemicals and doses, separation equipment, target water quality, and a representative sample when possible. Key trial metrics should include polished effluent TSS, turbidity, filter differential pressure or run time.
What packaging and storage conditions apply?
This listing uses 750 kg net big bag. The TDS also allows 25 kg kraft/PE bags with inner plastic bags or 750 kg net big bags. Store dry at 0-35 deg C, protect from sunlight and moisture, and use within the two-year shelf life.
