High-Performance GAC for Safe Drinking Water
GY 8-30 and GY 12-40 high-efficiency granular activated carbons are mainly used for beverage, drinking water and domestic water treatment. They effectively remove taste, odour, organics, residual chlorine and dissolved organic matter, showing strong adsorption capacity across a broad range of pollutants.
Made from selected premium bituminous coal with a high-quality binder through strictly controlled carbonization, activation and advanced post-treatment refining, this product offers a well-developed pore structure, very large surface area and fast adsorption kinetics. It is particularly effective on small-molecule organic pollutants, markedly improving taste, odour and overall water safety.
