Abstract

Water plays an important role in the main processes occurring in nature, as well as in human life. In industry, water is used as a source of raw materials and energy, as a coolant or heater, as a solvent, as an extractant, as a means of transporting raw materials and materials, and for a number of other needs.

MATERIALS AND METHODS

Industrial wastewater is generated during the processing and extraction of organic and inorganic raw materials. The sources of wastewater generation in technological processes include: 1) water generated as a result of chemical reactions (which are contaminated with starting materials and reaction products); 2) water in the form of free and bound moisture in raw materials and primary products, as well as moisture generated during processing processes; 3) water generated after washing raw materials, products and equipment; 4) running aqueous solutions; 5) aqueous extracts and absorbents; 6) cooling waters; 7) other wastewater; water from vacuum pumps, mixing condensers, hydrosol losses, washing of containers, equipment and buildings.
