Hanqi Environment has achieved new milestones in lithium iron phosphate (LFP) wastewater treatment for the new energy industry. Its self-developed Heavy Metal Ion Removal and Resource Recovery Technology has been successfully implemented at projects for Chuanheng Holding Group and Guangxi Times New Energy, with both facilities recently commissioned and officially handed over.

Industry Challenge:
As a key precursor for lithium-ion power battery cathodes and grid-scale energy storage materials, LFP production generates wastewater containing:
High-concentration phosphate ions
Multiple heavy metal ions
Complex contaminants posing significant treatment difficulties

Chuanheng Holding Group Project (Retrofit):
• Deployed Multi-effect Synergistic Heavy Metal Removal & Resource Recovery Technology
• Effective removal of:

• Fe/Mn/Mg ions

• Sulfate radicals

• Suspended solids
  • Integrated wastewater treatment units delivered:
  ✓ 40% footprint reduction
  ✓ 30% shorter construction timeline
  ✓ Zero disruption to main production
  ✓ Enhanced treatment efficiency
  ✓ Maximized resource recovery
  • Strengthened client's environmental competitiveness in new energy materials

Guangxi Times New Energy Project (Subsidiary of Huayou Cobalt):
• Provided process packages for:
a) Mother liquor line
b) Rinse water line
• Achieved under multi-pollutant conditions:
✓ Fe²⁺ reduced to <1 mg/L (98% removal)
✓ Comprehensive contaminant elimination
• Provides critical environmental support for large-scale lithium battery material production

Technology Advantages:
➤ High loading capacity
➤ Compact footprint
➤ Low chemical consumption
➤ Exceptional shock resistance
➤ Operational stability
➤ Adaptable process configurations

Corporate Commitment:
Upholding our long-term philosophy, Hanqi continuously advances technological and service capabilities to support the new energy industry’s green, low-carbon, and sustainable development goals.
