    摘要： The present invention relates to a manufacturing process for a tablet.
    The process comprises dry mixing of sodium bicarbonate and calcium carbonate powders in a weight ratio of 90 to 98 % of sodium bicarbonate and 10 to 2 % of calcium carbonate, at least 85 % of the particles of the sodium bicarbonate powder having a diameter up to 130 µm, the median diameter of the particles of the calcium carbonate powder being between 4 and 8 µm. Hereupon, whilst continue mixing, water is added to the mixture at a rate of between 5 to 15 % of the weight of the powders. Hereupon, mixing is continued until a homogeneous mixture has been obtained. Hereupon, the mixture is poured into molds and pressed under 2 to 6 kN/cm2, followed by drying the pressed tablets.
    The tablets so manufactured are used for the enhancement and resulting buffering action of water in amongst others swimming pools and swimming basins.
