In a cartridge for removal of impurities from water, an elongated tube is charged, between water-permeable barriers, with ion exchange resin of a type capable of removal of bacteria from water. Outside one such barrier, an inlet cap is charged with water-soluble bactericide in a shelf-stable, water-activatable form. Preferably, the bactericide is sodium salt of dichloroisocyanuric acid, in granular form.

Bacteria-removing cartridge and preparatory process

Bottler's liquid sugar is produced essentially from brown sugar, which is derived from cane sugar and crystallized in one or more intermediate strikes, by remelting the crystallized product of one or more intermediate strikes, filtering the remelted product, and passing the filtered product in contact with chloride form of Type-1 strong-base anion-exchange resin. An array of plural columns, which contain similar resin, is operated in a merry-go-round sequence allowing continuous operation. Countercurrent regeneration is preferred. Regeneration by an aqueous solution of hydrochloric acid followed by an aqueous solution of sodium chloride and sodium hydroxide allows service at 30.degree. C.
