(1) Sodium bisulfate tablets for use in the process of reducing the pH of water in industrial and commercial aquatics applications, namely, for swimming pools, drinking water, mineral water, waste water, water for agricultural and food processing use.
Described is a method for improving the operation of an electrolytic cell having an anolyte compartment, a catholyte compartment and a synthetic diaphragm separating the compartments, wherein liquid anolyte is introduced into the anolyte compartment and flows through the diaphragm into the catholyte compartment, which method involves introducing particulate material comprising halocarbon polymer short fiber, e.g., fluorocarbon polymer short fiber, into the anolyte compartment in amounts sufficient to lower the flow of liquid anolyte through the diaphragm into the catholyte compartment. In the case of an electrolytic cell wherein aqueous alkali metal chloride, e.g., sodium chloride, anolyte is introduced continuously into the anolyte compartment, thereby to produce a catholyte liquor containing alkali metal hydroxide and hypochlorite ion, the foregoing method is useful for decreasing the concentration of hypochlorite ion in the catholyte liquor and oftentimes increasing the concentration of alkali metal hydroxide in the catholyte liquor. Also describes adding at least one member chosen from halocarbon polymer microfibril, halocarbon polymer fiber, clay mineral, oxides and/or hydroxides of alkaline earth metals, and zirconium oxide/hydroxide in conjunction with the halocarbon polymer short fiber to the anolyte compartment, e.g., while the cell is operating.

Describes a liquid-permeable diaphragm assembly for use in electrolytic cells, e.g., chlor-alkali electrolytic cells. The diaphragm assembly includes a foraminous cathode, a liquid permeable base mat comprising synthetic polymeric material that is at least partially resistant to the environment within the electrolytic cell on the foraminous cathode, and a topcoat of water-insoluble particulate material on the base mat. The topcoat is deposited on the base mat from an aqueous slurry comprising (i) at least one oxide, boride, carbide, nitride or silicate of a valve metal, (ii) clay mineral, (iii) hydrous metal oxide chosen from the hydrous oxides of magnesium, the hydrous oxides of zirconium, and mixtures of such hydrous metal oxides, and (iv) alkali metal polyphosphate.

Describes a method for lowering the flow of liquid anolyte through perforations in the diaphragm of a diaphragm electrolytic cell, e.g., a chlor-alkali diaphragm electrolytic cell, comprising introducing ceramic fiber into the anolyte compartment of the electrolytic cell, e.g., during cell operation. The benefits described for lowering the flow of anolyte liquor through the diaphragm of a chlor-alkali diaphragm electrolytic cell are increasing the concentration of alkali metal hydroxide, e.g., sodium hydroxide, and decreasing the concentration of hypochlorite ion, e.g., sodium hypochlorite, in the catholyte liquor. Also describes introducing dopant material and/or fibers comprising halogen-containing polymer, e.g., fluorocarbon polymer fibers, into the anolyte compartment of the electrolytic cell in conjunction with the addition of ceramic fiber into the anolyte compartment, e.g., during cell operation.
