Multipure Drinking Water Systems

Multipure Drinking Water Systems utilize Multipure’s innovative and proprietary Solid Carbon Block-based filter. This filter employs multiple components and materials to reduce the presence of a wide variety of contaminants in water.

Mechanical Filtration: The water passes through a pre-filter that traps dirt, sand, and particles that affect the taste and overall appearance of the water. After passing through the pre-filter, the water then passes through the Solid Carbon Block, where particles as small as 0.5 microns are physically trapped by the filter. Asbestos, cysts, and particulates are reduced through mechanical filtration at the sub-micron level.

Electrokinetic Adsorption: The pre-filter acquires a positive molecular charge as water passes through it. Since most contaminants exhibit a negative charge in water, the filter fibers electrokinetically attract these negatively-charged particles onto the positively-charged filter surface. Generally, these particles are too small to be trapped by mechanical filtration.

Physiochemical Adsorption: The carbon block filter is a blend of selected activated carbons and other media that reduce aesthetic contaminants and health-related contaminants by adsorbing particles to its surface. Because the carbon block is densely compacted, it provides a longer contact time with the water, and thus, better performance than many other filtration technologies.

Nationally recognized standards established for the drinking water treatment industry confirm that the most effective systems for the removal of both aesthetic and harmful contaminants are those that utilize Solid Carbon Block filters. Multipure is the original developer of Solid Carbon Block technology and has been the leader and innovator in the water treatment industry since 1970. Multipure, and its remarkable Solid Carbon Block filter, is synonymous with superior quality and exceptional innovation. With a Multipure Drinking Water System, you are guaranteed the best.

Adsorption vs. Absorption

Multipure filtration utilizes a process called adsorption. Adsorption differs from the more commonly known absorption; adsorption refers to the transfer of the particles of a gas, liquid, or dissolved solid onto a surface, while absorption refers to the incorporation of a solid, liquid or gas into another solid, liquid, or gas.

The Multipure filter uses adsorption to transfer contaminants onto the filter’s surface and remove it from the water stream. The water itself is temporarily absorbed by the filter material (much like a sponge absorbing water), but the contaminants are adsorbed to the filter surface, creating a layer on the surface as it is removed from the water stream.
