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.
