HydroGraph has engineered an advanced graphene-based filtration material capable of removing nearly all toxic industrial dyes from wastewater within 10 minutes. This breakthrough offers a powerful solution to one of the world’s most persistent pollution problems, especially from textile, chemical, and manufacturing industries. • The graphene uses an ultra-high surface area to rapidly جذب (bind) dye molecules at the molecular level. • It is effective against some of the most stubborn pollutants,
