- 9. The article of claim 1 wherein each pellet has a width ranging from about 5 to 30 mm., a height ranging from about 10 to 80 mm. and a depth ranging from about 10 to 30 mm.
- 10. The article of claim 1 wherein the water soluble container will dissolve when exposed to a water spray having a minimum water temperature of about 40.degree. F. and a minimum nozzle pressure of about 25 to 30 psig such that the pelletized functional material is exposed in about 0.5-3 minutes.
- 11. The article of claim 7 wherein the conductive filler is soda ash, sodium sulfate, sodium chloride, borax, sodium bicarbonate or sodium sesquicarbonate.
- 12. The article of claim 1 wherein the sequestering agent is an alkali metal phosphate, sodium aluminosilicate, sodium carbonate, ethylenediaminetetraacetic acid, nitrilotriacetic acid, a phosphonate, a polyacrylic acid or polyacrylate, a copolymer of acrylic acid, a copolymer of itaconic acid, a zeolite, or citric acid.
- 13. An article of manufacture which comprises:
- (a) a dispenser containing an aqueous liquid spray means;
- (b) a sealed water soluble container; and
- (c) an institutional multiple use amount of greater than about 200 grams of a pelletized water soluble of dispersible functional composition contained within said water soluble container, wherein said water soluble container fits within said dispenser and is capable of forming an aqueous solution by action of said liquid spray on said pelletized functional composition, and the pelletized functional composition comprises:
- (i) an effective buffering amount of a buffering agent;
- (ii) an effective amount of an alkalinity and ammonium source to provide a source of mild alkalinity and desired amount of ammonia;
- (iii) about 8-30 wt-% of a sequestering agent; and
- (iv) about 12-28 wt-% of a surfactant.
- 14. The article of claim 13 wherein the water soluble container comprises a water soluble bag.
- 15. The article of claim 13 wherein the water soluble container has a water temperature range for solubility of about 34.degree. F. minimum.
- 16. The article of claim 13 wherein the water soluble container comprises a water soluble polymer selected from the group consisting of a polyvinyl alcohol, polyvinyl acetate, polyvinyl pyrrolidine or mixtures thereof.
- 17. The article of claim 13 wherein the water soluble container contains about 200 grams to 5,000 grams of pelletized functional material.
- 18. The article of claim 13 wherein each pellet has a mass of about 2 to 30 grams.
- 19. The article of claim 13 wherein each pellet has a width ranging from about 5 to 30 mm., a height ranging from about 10 to 80 mm., and a depth ranging from about 10 to 30 mm.
- 20. The article of claim 13 wherein the water soluble container will dissolve when exposed to a water spray having a minimum water temperature of about 40.degree. F. and a minimum nozzle pressure of about 25 to 30 psig such that the pelletized functional material is exposed in about 0.5-3 minutes.
- 21. The article of claim 13 wherein the sequestering agent is an alkali metal phosphate, sodium aluminosilicate, sodium carbonate, ethylenediaminetetraacetic acid, nitrilotriacetic acid, a phosphonate, a polyacrylic acid or polyacrylate, a copolymer of acrylic acid, a copolymer of itaconic acid, a zeolite, or citric acid.
