SURSORB BAL is a spherical porous permanganate impregnated activated alumina. It is specially designed for removing acid gases and odours. SURSORB BAL has been specially engineered to provide the highest oxidation potential available, thus assuring the highest overall performance. The chemisorptive process removes contaminant gases using adsorption, and oxidation. It demonstrates a higher working capacity for broad-spectrum control in applications where multiple contaminant gases are present.
