Why It Matters
WWTP and industrial operators buy cationic emulsion or dry polyacrylamide by the tote to condition biosolids before belt-press, screw-press or centrifuge dewatering. Better conditioning raises cake solids and directly cuts the cost of hauling and disposing of wet sludge
Solution Approach
WWTP and industrial operators buy cationic emulsion or dry polyacrylamide by the tote to condition biosolids before belt-press, screw-press or centrifuge dewatering. Better conditioning raises cake solids and directly cuts the cost of hauling and disposing of wet sludge RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.
Typical Treatment Workflow
1
System Assessment
Characterize operating conditions—fluid composition, temperature, pressure, flow rates—and benchmark current treatment performance.
2
Chemistry Selection
Match base chemicals to your operating envelope. Factor in compatibility with existing programs, regulatory constraints, and downstream impacts.
3
Dosage & Delivery
Determine optimal treat rates through jar testing or field trials. Configure packaging (drums, totes, ISO tanks) to match consumption and storage logistics.
4
Monitoring & Adjustment
Track KPIs—coupon rates, residuals, separator performance, water quality. Adjust chemistry and dosage as conditions change.
Recommended Chemistries (5)
Polyacrylamide Flocculant
CAS 9003-05-8
Polymers & Resins
Anionic PAM flocculant
In catalog (generic grade). High-molecular-weight polyacrylamide bridges destabilized solids into large, shear-resistant flocs that release free water on the press

PolyDADMAC
CAS 26062-79-3
Specialty Additives
Cationic coagulant polymer
In catalog. Low-MW high-cationic-charge coagulant neutralizes negatively charged colloids and conditions sludge; often paired with PAM as a dual program
Full Details
Cationic emulsion polyacrylamide (charge-density graded)
CAS 9003-05-8
Polymers & Resins
Anionic PAM flocculant
Cationic charge binds the anionic surface of biological sludge so the polymer flocculates and dewaters where anionic PAM cannot

High-MW dry cationic polyacrylamide
CAS 9003-05-8
Polymers & Resins
Anionic PAM flocculant
Solid form gives long shelf life and a low cost-per-active-pound for makedown systems on larger plants
Full Details
Anionic polyacrylamide
CAS 9003-05-8
Polymers & Resins
Anionic PAM flocculant
Used for gravity thickening and mineral/inorganic sludges where solids carry a positive or neutral surface charge
