Abstract
A water treatment cartridge and method for producing ultrapure water is described. The cartridge comprises a container having therein a particulate admixture of activated carbon and mixed bed ion exchange resins. A source of water, preferably pretreated, is passed through the container, preferably following treatment by one or more cartridges containing mixed bed ion exchange resins. The carbon in the admixed cartridge removes residual organic contamination from the water and the resins remove ionic contamination from the carbon, without re-introducing organic material to the water.
Claims12
The method for providing substantially de-ionized water with reduced organic contamination which comprises passing water through a cartridge containing a particulate admixture of activated carbon and mixed ion exchange resins.
A water treatment cartridge for obtaining ultrapure water with high resistivity and reduced organic contamination which comprises a container having an inlet and outlet for water and containing in the flow path between said inlet and outlet an effective admixture of mixed ion exchange resins and activated carbon.
