Using high-quality fruit shell charcoal and coal-based activated carbon as raw materials, supplemented with edible grade adhesives, using high-tech technology and processed by a special process, it integrates adsorption, filtration, interception and catalysis, and can effectively remove water The organic matter, residual chlorine and other radioactive substances have the effect of decoloring and removing odor. 2. Type White-head sintered activated carbon filter element, black-head sintered activated carbon filter element with skeleton, and granular activated carbon filter element. 3. Features: The activated carbon filter element is a true deep structure with dual functions of filtration and purification. The filter accuracy is 10 microns nominal filtration accuracy. There is no need to add filter aids during the use, and no need to carry out filtration after carbon treatment.
