Ceramic consignace are advanced filtration materials, or contaminal (TiO contained) from inorganic compounds such as aluna (Al contact Os alua), zirconia (Zro containen), silica (SiO containment), or containia (TiO containment) entl. These materials are sintered at high temperatures to form a rigid, porous structure with precisele controlled pore sizes ranging from microfiltration (0,1- 1µm) down nanano filtraoden (1- 10 nm).

Thee Role of Activated Carbon

Aktywny karbon is a form of karbon that has been processed to create an extensive network of internal pores, yielding a surface area typically between 500 and1 500 m ² / g. This enormous surface area, combined with a high density of functival groups on thee pore walls, enables activated carbon to adsorb organic percules, chlorine, baille organic compounds (VOCs), and many microcommentants diophygvar der Waals forces and chemisorption.
