Highly alkaline detergent compositions are prepared by mixing together, in a mixing device, a melt of alkaline material with a hardness sequestering agent, such as an alkali metal complex phosphate sequestrant. The resulting mixture is, then, pelletized on a chill belt. A source of solid active chlorine pellets is combined with the pelletized mixture. Chlorine degradation is essentially eliminated by combining the alkaline material pellets with the pelletized chlorine source.

A process for manufacturing a highly alkaline detergent pellet and chlorine pellet mixture, comprising: (a) preparing a first quantity of pellets containing a caustic and a hardness sequestering agent by: (i) heating a concentrated aqueious alkaline material selected from the group consisting of alkali metal hydroxides, and mixtures thereof to an elevated temperature; (ii) admixing a sequestrant with the alkali metal hydroxide to form a detergent mixture; (iii) dispensing the concentrated aqueous alkaline material into a feed tube; (iv) dropping droplets of the mixture from feed tube box onto a chill belt to form solid pellets thereof, consisting essentially of alkaline material and sequestrant; (b) measuring a second quantity of pre-prepared chlorine pellets; (c) admixing together a measured amount of the first quantity and the second quantity of pellets.
