Industry Problem

In high load water treatment systems conventional coagulation processes often face serious challenges:

• Poor settling performance in high turbidity water
• Stable colloidal particles difficult to destabilize
• Excessive consumption of inorganic coagulants
• Large sludge volume and difficult dewatering

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

The root cause is high electrostatic stability combined with insufficient polymer bridging capability.

Technical Principle

• Strong charge neutralization of negatively charged particles
• Advanced polymer bridging forming large dense flocs
• Synergistic coagulation with PAC
• Optimized sludge structure for better dewatering

FAQ

• What is the difference between DA406 and DA405

DA406 has higher viscosity and stronger flocculation capability

• Can DA406 replace PAC completely

It may partially replace but is usually used together with PAC

• Is DA406 safe for drinking water

Yes it is certified under NSF standards

• Should it be diluted before use

Yes dilution improves dosing performance
