Product Overview

DA405 is a high viscosity PolyDADMAC liquid cationic polymer designed for advanced coagulation and flocculation processes.

It is suitable for high turbidity water drinking water clarification industrial wastewater with high suspended solids and sludge reduction systems.

Typical properties include solid content around 40 percent viscosity between 5000 and 8000 cps and strong cationic charge density.

Problem

• Poor floc formation
• High chemical consumption
• Slow settling rates
• Excess sludge production

Common in river water textile wastewater and industrial effluent systems.

Cause

• High negative charge of particles
• Insufficient polymer bridging
• Low molecular weight chemicals
• Over reliance on inorganic coagulants

Solution

• Strong charge neutralization
• Large floc formation through polymer bridging
• Reduced chemical consumption
• Lower sludge volume
• Wide pH adaptability
