Decolorizing high-color, high-organic wastewater is a significant challenge. A poorly chosen or misapplied PolyDADMAC (PDADMAC) can result in poor decolorization, high costs, and process issues.

WT-104 PDADMAC from Luterra Advanced Materials is a cationic organic polymer flocculant with high charge density and good water solubility. It is specifically designed for decolorizing high-color, high-organic wastewater, and can be combined with other coagulants for comprehensive treatment. This guide covers five critical mistakes to avoid when selecting and using PolyDADMAC.
Mistake #1: Using a Product That Can't Achieve High Decolorization Rates
For wastewater with high color, especially from printing, dyeing, or pulping operations, achieving effective color removal requires a high-charge-density cationic polymer.
WT-104 has a color removal rate of ≥95%. Its high cationic charge density effectively neutralizes the negative charges on dye molecules and organic contaminants, leading to their precipitation and removal.
Mistake #2: Overlooking the Synergistic Effect with Inorganic Coagulants
Using PDADMAC alone can be effective but using it as part of a dual treatment train is often more powerful.
WT-104 can be combined with PAC or PFS to achieve both decolorization and flocculation effects. A typical approach is to use an inorganic coagulant for turbidity removal and PDADMAC for targeted color removal, or vice versa.
Mistake #3: Not Selecting the Right Application for Its Strengths
PDADMAC is a specialist, not a generalist. Using it for applications where simple turbidity removal is the goal is not the most economical choice.
WT-104 is specifically designed for decolorizing high-color, high-organic wastewater. Its strengths are in applications like printing and dyeing wastewater, papermaking wastewater and pulping black liquor, and paint and ink wastewater.
Mistake #4: Ignoring Compatibility with Piping and Storage Systems
While not highly corrosive, some products may have compatibility issues with certain materials.
WT-104 has low corrosivity and is mild. PE, PVC, plastic tanks, and stainless steel tanks are suitable. Standard water pipes can be used without special anti-corrosion treatment.
Mistake #5: Incorrect Dilution or Addition Point
Adding the product neat or without proper dilution can lead to localized high concentrations, reducing efficiency and potentially causing issues.
For optimal results with WT-104:
Addition: Use neat or dilute 5–10 times before dosing.
Dosage: 10–100 ppm.
Application: Add to the wastewater stream at a point of good mixing.
