In the well‐known Clark process for the removal of carbonates, the water is treated with lime. Owing, however, to the solubility of lime as well as that of the normal carbonate the total precipitation of carbonates is never quite complete, but an equilibrium is reached with small amounts remaining in solution. Such a water is not suited for mashing, and as there may be objections to acids for the neutralisation of the alkalinity the author prefers to use the add sulphate of soda or potash. It is shown that such procedure affords satisfactory results.
