Scientific Study Shows HydroGraph Graphene Removes 100% Of Toxic Industrial Dyes In Minutes, Offering Sustainable, Scalable Solution For Wastewater Treatment

Peer-reviewed research proves that HydroGraph ultra-pure graphene offers cost-effective, reusable adsorption medium for wastewater purification

HydroGraph Inc. (“HydroGraph”), a leading producer of ultra-pure graphene, today announced the publication of a peer-reviewed study that demonstrates the potential of using HydroGraph graphene as a scalable solution for industrial wastewater treatment. The study, published in FlatChem (Elsevier), confirms that HydroGraph’s graphene can remove 100% of six organic dyes from wastewater within 10 minutes.

The global wastewater market is projected to reach $20.01B by 2025 and $28.95B by 2032 at a CAGR of 5.4%. Organic dyes are a major pollutant in local water sources, and wastewater is often discharged with minimal treatment, affecting flora and fauna and ultimately entering the food chain. Conventional filtration methods to treat wastewater and remove dyes can be costly and difficult to scale.

The use of HydroGraph’s few-layered graphene, produced via a patented chamber explosion method, has been shown to remove 100% of dye contaminants through adsorption, providing a larger surface area for molecular adherence. Graphene is also cost-effective, scalable, and recyclable, making it more attractive than other treatment methods. Recycling experiments demonstrated 97% to 100% dye removal within 15 to 60 minutes.

Using graphene for wastewater purification is more sustainable than other coagulation/flocculation techniques, with a lower chemical footprint. Graphene also uses less energy than pressure-driven membranes or some advanced oxygenation processes (AOPs). Graphene adsorbents can also be regenerated multiple times, cutting waste and lifetime costs.

“Industrial wastewater is one of the biggest pollutants, creating human health risks and threatening the global ecosystem,” said Kjirstin Breure, President and CEO 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.”

Graphene is a two-dimensional allotrope of Carbon with a honeycomb structure. It can remove pollutants from water in its pristine form, as a composite, or as graphene oxide (GO) or reduced graphene oxide (rGO). While graphene has a high adsorption capacity, the large-scale production of graphene has been challenging due to its high costs and the use of toxic reagents, which result in metal contaminants. HydroGraph has solved those issues by using a controlled chamber explosion method to produce few-layered graphene nanosheets. This production method is cost-effective and scalable, with the near elimination of harmful byproducts, resulting in a greener synthetic process. Graphene adsorption aligns with the United Nations’ Sustainable Development Goals (SDGs), specifically the call for clean water (SDG 6); industry, innovation, and infrastructure (SDG 9); responsible consumption and production (SDG 12); and climate action (SDG 13).

HydroGraph continues to test graphene for dye removal with plans to pursue pilot projects in the next three to six months. The company is currently looking to partner with textile, pulp and paper, and paint manufacturers.

About Hydrograph
HydroGraph is a leading producer of pristine graphene using an “explosion synthesis” process, which allows for exceptional purity, low energy use, and identical batches. The quality, performance, and consistency of Hydrography’s graphene follow the Graphene Council’s Verified Graphene Producer standards, of which very few graphene producers are able to meet.
