Hydrograph's graphene removes industrial dyes

Executive Summary

• Hydrograph Inc. published a peer-reviewed study in FlatChem (Elsevier) demonstrating that its proprietary graphene can remove 100% of six organic dyes from industrial wastewater within 10 minutes.
• The study highlights graphene as a scalable, cost-effective, and sustainable alternative to conventional filtration methods, which are often costly and difficult to scale.
• Hydrograph plans to pursue pilot projects within the next three to six months and is actively seeking partnerships with textile, pulp and paper, and paint manufacturers.

Key Details

• Study Publication: The findings were published in FlatChem, an Elsevier journal.
• Performance Metrics:
  • Removed 100% of six specific organic dyes from wastewater.
  • Removal achieved within 10 minutes.
  • Recycling experiments demonstrated 97% to 100% dye removal within 15 to 60 minutes.
• Technology: Uses few-layered graphene produced via a patented "chamber explosion method," which is described as cost-effective, scalable, and producing near-zero harmful byproducts.
• Market Context: The global wastewater market is projected to reach $20.01 billion by 2025 and $28.95 billion by 2032 (CAGR of 5.4%).
• Advantages over Competitors:
  • Lower chemical footprint than coagulation/flocculation techniques.
  • Lower energy usage than pressure-driven membranes or advanced oxygenation processes (AOPs).
  • Adsorbents can be regenerated multiple times, reducing waste and lifetime costs.
• Strategic Outlook:
  • Pilot projects are planned for the next 3–6 months.
  • Target sectors for partnership include textile, pulp and paper, and paint manufacturers.
  • Alignment with UN Sustainable Development Goals (SDG 6, 9, 12, and 13).

Notable Quotes

• "Industrial wastewater is one of the biggest pollutants, creating human health risks and threatening the global ecosystem," said Kjirstin Breure, president and chief executive officer of Hydrograph. "This new study proves that graphene is extremely effective in removing toxins from industrial organic dyes, and Hydrograph is one of the few companies able to deliver high-quality, reusable graphene for wastewater treatment."
