Description

I

The invention relates to the non-alcoholic industry, in particular to methods for preparing water for the production of non-alcoholic beverages.

The purpose of the invention is to reduce the reagent consumption for the regeneration of the cation exchanger.

The method is carried out as follows.

The water to be treated is passed through a K-cation filter, then filtered through ceramics. The C-filter, performed bactericidal purification, after which the softened water is mixed with the original water, previously filtered through a ceramic filter, its volume is determined by its hardness and volume. mixed water. Cooled and used for the production of non-alcoholic beverages.

After a fixed period, K-cationite is regenerated with a 10% solution of potassium chloride, which is prepared in a salt solvent and is fed from the bottom of the filter, thereby loosening the ion exchanger with simultaneous regeneration. The regeneration is carried out sequentially in three portions of the regenerating solution, the volumes of which are equal to the volume of the cation exchanger filling the column. In this case, the first portion of the solution regenerates the cation exchanger by 60-70% and is discharged into the tank to collect the regeneration solution (regenerate). The second and third portions of the solution are poured into other tanks and reused for subsequent regeneration of the cation exchanger as the first batch. The first portion of the solution is treated with dry potassium carbonate. When this occurs, the reaction of CaC + .- iCaCOj + + 2 KC1.

The resulting precipitate CaCO, -j (chalk) is separated and used for the needs of the enterprise or is realized, and the solution above the precipitate is pumped through the filter press to a salt solvent and reused. Regeneration

, K-cationification with sequential mixing of the obtained water with the initial one ensures the production of water of optimal composition for production.

soft drinks. Recovery of reclaim and recirculation of regenerating i tacTBOpa provides waste-free water treatment technology and leads to savings in reagents. Water is passed through a K-cation exchanger: where almost the replacement of calcium and magnesium ions by potassium ions occurs. The total hardness decreases, 5 up to 0.5 mEq / l. The resulting softened water is mixed with the original water in a 4: 1 ratio. Moreover, the untreated and source water is shifted by shifting the filter, lowering it through the ceramic filter.

An organoleptic evaluation of the quality of beverages prepared on this water was carried out immediately on the day of the production of beverages, then after two, seven, twelve and fifteen days. iKaK c is studied from experimental data, the quality of beverages obtained in K-cationic water, by organoleptic and.f chemical indicators are somewhat higher than the control samples (Table 1), the beverages are more stable (the process of deterioration was recorded only on day 15) at that. Time as a GOST provided for the storage of beverages no more than 7 days.

Regeneration of the K-cation filter is carried out in three portions of a 10% solution of KS 1.

The concentration of Ca ions in the regenerator is shown in Table 2.

In the first portion of the calcium calcium regenerator, an equivalent amount of carbolith is used for the needs.

METHOD FOR PREPARING WATER FOR THE PRODUCTION OF SOFT DRINKS, which involves passing water through a K-cationite filter, mixing it with the source water and regenerating it with a 'reagent - potassium chloride, which means that in order to reduce the consumption of the reagent for regeneration cation exchanger, the solution after regeneration of cation exchanger is treated * with potassium carbonate *, the precipitate formed is separated from the liquid phase, the latter is filtered and used to regenerate the cation exchanger, and the treated and initial water are filtered before mixing. δοϊβκι ns
