At the enterprise, for the first time in the world practice, it was possible to avoid pollution of reservoirs by sewage.

Instead of the usual general runoff, closed cycles were used for each production.

This allowed to purify the waste water, and then again to put it into circulation.

The water cooling was changed to air cooling: so-called evaporators of cooling were applied.
