Polydadmac for Potable Water Treatment and Municipal Water Treatment | Drinking Water Purification
Primary keywords: Potable water treatment, Municipal water treatment, Drinking water purification
Overview
Polydadmac is a high-charge cationic polymer for potable water treatment. In municipal water treatment operations it neutralizes negatively charged colloids and produces compact flocs for clear settled water and longer filter runs. The portfolio includes liquid and powder grades to suit different make-up systems and dosing equipment.
How It Works
Coagulation and Flocculation
Strong positive charges destabilize colloids and form dense, fast-settling flocs that improve clarification and filtration.
Program Flexibility
Use as a primary coagulant or combine with polyaluminum programs when enhanced coagulation is needed for color or NOM control.
Product Forms and Selection
Liquid Grades
- Solids approximately 20–50%
- Multiple molecular weight and viscosity bands
- Wide operating pH window for variable raw water
Powder Grades
- Solids ≥90% with convenient dry handling
- Typical 1% solution pH around 2.0–6.0
- Charge density typically 2–3 meq/g
Typical Use in Drinking Water Purification
- Prepare a working solution before dosing. Liquid grade: 0.5–5% by solids; Powder grade: 0.5–10% by solids.
- Confirm dose by jar tests and select injection points for fast dispersion without floc breakage.
- Operate across broad raw water conditions using the product’s wide pH adaptability.
Technical Highlights

Expected Outcomes for Municipal Water Treatment
- Lower settled water turbidity and improved filter effluent quality.
- Better organic removal supporting DBP control strategies.
- Potential reduction of metal salt usage when used as a primary coagulant.
- Reduced sludge volume and more consistent dewatering.
