Definitions
- the proposed invention is available for pulp and paper products, in particular, for the purchase of the equipment for the purchase;
- Waste of the listed income is a greater amount of fresh water used for the production of income and expenses for the subsequent calculation of the profit and loss.
- This method makes it possible to significantly increase the economical process of pulp production due to the use of fresh water in good condition.
- this method gives a comparatively low output of the product and does not prevent the unnecessarily high output of the product. Otherwise, use in the form of a fresh medium with a low concentration of excess activated sludge.
- the posed task is solved due to the fact that, in the case of obtaining a different product by saturating the external medium with solid anhydrous, the solid medium is consumed

- the proposed method provides for the use of wastewater from biological waste water treatment with an excess of active income of 18-40.
- a good concentration obtained by preliminarily compensating for excess active sludge in special restoratives is optimal, i.e. ⁇ bes ⁇ echivae ⁇ ⁇ vyshenn ⁇ e s ⁇ de ⁇ zhanie in va ⁇ chn ⁇ m ⁇ as ⁇ v ⁇ e ⁇ du ⁇ v ⁇ isl ⁇ g ⁇ or schel ⁇ chn ⁇ g ⁇ gid ⁇ liza, ⁇ b ⁇ azuyuschi ⁇ sya in ⁇ tsesse eg ⁇ ⁇ ig ⁇ vleniya and ⁇ a ⁇ already ⁇ mechal ⁇ s higher s ⁇ s ⁇ bs ⁇ vuyuschi ⁇ ⁇ vysheniyu e ⁇ e ⁇ ivn ⁇ s ⁇ i va ⁇ i tsellyul ⁇ zy.

- the obtained product volume is supplied to the absorber to saturate with serous anhydride at a temperature of 35-45 ° C and a concentration of 2.5-5.5% of the volume of the product is absorbed.
- the obtained alkaline hydrated solution is supplied in an absorber for saturation with selenium anhydride at a temperature of 35-45 ° C to a concentration of 2.5-5.5% by weight
- Example 1 The method is illustrated by the following examples: Example 1.
- the factory is prepared for the following:
- EXAMPLE 3 illustrates a well-known method for the production of a proprietary device, according to an author's testimony of the Felsov SSSE 746002
