Millistak+ A Cartridge Filters

Millistak+ A Cartridge Filters

Description

Millistak+ Series A clarification/prefiltration filters incorporate a carbon impregnated media for decolorization and removal of trace contaminants. Carbon is a complex material and each application requires distinct adsorption characteristics to achieve the desired result. Carbon's adsorption affinity for a particular impurity varies widely depending on the nature of the impurity and the actual process liquid chemistry.

Millistak+ 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.

Benefits

Tortuous rigid matrix prevents channeling of the flow stream
The use of cross-linking wet strength binders results in negligible carbon fine release
Non-toxic
Millistak+ media eliminates the need for and the labor intensive cleaning of carbon treatment stirring tanks

Advantages Over Powdered Activated Carbon

Millistak+ Series A media, an activated carbon bonded together to form a rigid matrix, quantitatively retains more contaminants from a solution than the equivalent weight of powdered carbon. The rigid matrix of the Millistak+ media forces the liquid stream to endure intimate contact with the activated carbon on the surface and within the pores of the carbon particles. This provides optimal removal of contaminants from the liquid stream.

Powdered carbon removes contaminants from a liquid by adsorbing the contaminants on the pore walls of the carbon. The impurities are held by a weak electrostatic force known as "Van der Waals Force." Filtering removes the powdered carbon but often channeling occurs where the liquid passes through openings in the bed of carbon.

Millistak+ offers single pass operation and high flow rate conditions for speed and convenience. Powdered carbon requires long contact time between the carbon and the liquid to reach adsorption equilibrium prior to filtration. Millistak+ media provides speed, convenience, and optimal performance.

The filters are composed of an activated carbon impregnated media, polypropylene spacers, end caps and edge seals, stainless steel compression bands, silicone seals (standard).

Typical extractable levels have been determined by laboratory analysis utilizing a dynamic flow rinse procedure. Inorganic extractables are quantified by atomic emission analytical techniques. The results are expressed as milligram per gram of media weight subsequent to the standard recommended flush of 50 L/m² (5 L/ft²) of media surface area.
