Industry Problem

In extreme water treatment scenarios standard flocculants and coagulants often fail to deliver stable performance:

• Very slow settling in ultra high turbidity water
• Fine colloids remain suspended after treatment
• Excessive sludge generation
• Inefficient solid liquid separation in high load systems

These problems are common in mining wastewater industrial effluent and textile wastewater systems.

The core issue is insufficient molecular strength and bridging capability under extreme load conditions.

Technical Principle

• Ultra strong charge neutralization of colloidal particles
• Maximum polymer bridging forming large dense flocs
• Accelerated settling through heavy floc formation
• Enhanced sludge structure for easier dewatering

Typical Specifications

Applications

• Drinking water treatment for high turbidity conditions
• Mining wastewater and mineral processing

FAQ

• What makes DA407 different from DA406

DA407 has higher viscosity and stronger flocculation capability

• Is it suitable for drinking water treatment

Yes it meets NSF standards for potable water

• Can it be used without PAC

Yes but best performance is achieved when combined with PAC

• Does higher viscosity mean better performance

It is better for extreme conditions but may not be necessary for normal water

• How to determine dosage

Jar testing is recommended for optimal results
