Millistak+ A Series clarification/prefiltration filters incorporate a carbon impregnated media for decolorization and removal of trace contaminants. Millistak+ A media is formulated with carbon retained in a rigid structure by a cellulose matrix. The matrix presents a diverted flow path to ensure intimate contact of the impurities on the surfaces and within the pores of the carbon. The outcome is optimum adsorption of the impurities.
