An apparatus for preparing a chemical solution includes a lower housing and an upper housing. The lower housing has a base, an upper plate having a central opening, and a side wall. A grid mounted on the upper plate covers the opening. A wall within the lower housing divides the interior of the lower housing into a central inner chamber and an annular outer chamber; this wall extends into an upper portion of the lower housing. One portion of the wall has a reduced height to permit fluid flow from the inner chamber to the outer chamber. A nozzle is mounted in the inner chamber for discharging fluid into the inner chamber, and causes local elevation of a portion of the fluid surface above the grid. The nozzle may be an eductor creating a venturi effect to draw fluid into the eductor.

Method and means for the preparation of solutions from dry chemicals

A solid calcium hypochlorite composition comprising a mixture of: solid calcium hypochlorite; a scale-inhibiting effective amount of a primarily scale-inhibiting alkali metal phosphate; and an effective residue-dispersing amount of primarily residue-dispersing alkali metal phosphate.

Calcium hypochlorite/scale inhibitor/residue disperser triblend

A non-Division 5.1 Oxidizer tablet consisting essentially of a blend of hydrated calcium hypochlorite with magnesium sulfate heptahydrate, wherein the blend contains at least about 17% by weight of water based on the total weight of the blend and the dissolving rate of the tablet is less than 150 grams per day.

Calcium hypochlorite blended tablets

A non-Division 5.1 Oxidizer tablet consisting essentially of a blend of hydrated calcium hypochlorite with magnesium sulfate heptahydrate, wherein the blend contains at least about 17% by weight of water based on the total weight of the blend; contains from about 0.1% to about 10% of lime based on the total weight of the hydrated calcium hypochlorate and magnesium sulfate heptahydrate and the average dissolving rate of the tablet is less than 150 grams per day.
