Definitions
- Another object of this invention is the provision of such composition in a "user-friendly" form, wherein the composition is in the form of a solid agglomerate, such as a tablet, which provides an effective amount of each biocidal component and which is stable in the dry state as well as in the effluent of an erosion feeder.
- the present invention is dir ⁇ ected to a novel dry biocidal composition, the active ingredient of which comprises an oxidizing biocide and a non-oxidizing biocide.
- the biocidal composition contain between about 5 to 50% by weight of the halogen stabilizer, between about 5 to 50% by weight of the ultraviolet light stabilizer, and between about 5 to 50% by weight of the corrosion inhibitor, based on the weight of the biocidal product (including additives)
- the biocidal product is in the form of a solid, shaped agglomerate such as a tablet.
- the tablets not only provide the desired ratio of halogen and triazine (e.g., 1-3 parts halogen: 1 part triazine) but are designed to do so in a predetermined volume of water. For instance, because most spas contain a relatively small volume of water, it is preferable to use a tablet that provides 3 ppm of halogen and 1 ppm triazine per 250 gallons or 500 gallons of water.
- a Marley open double flow cooling tower with 10,000 gallon capacity and 80,000 gallons per day make up water flow was treated over a 104 day period with a formulation designated CN-530.
- the CN-530 used in this example had two separate formulations. The first formulation contained 87% CN-363 (see Example 1), 3% sodium metasilicate pentahydrate and 10% Princep Caliber 90 (PC-90) and the second formulation contained 82% CN-363, 3% sodium metasilicate pentahydrate and 15% PC-90. In the following description, the percent of PC-90 is stated along with the compound number to distinguish the first CN-530 formulation from the second CN-530 formulation) .
- the tower used for this test provided a perfect environment for algae *
