Industry Problem

In the most challenging water treatment environments even high performance polymers may fail:

• Ultra high turbidity water with fine suspended solids
• Complex industrial wastewater with stable colloids
• Slow or incomplete floc formation
• Excess sludge and difficult dewatering

These issues are common in mining wastewater textile effluent and oilfield water systems.

The core challenge is extremely stable colloids requiring maximum charge neutralization and strong molecular bridging.

Technical Principle

• Maximum charge neutralization for rapid destabilization
• Ultra strong polymer bridging for large floc formation
• Accelerated settling for faster clarification
• Improved sludge compaction and dewatering
