Salt has a wide range of uses in various industries. Here are the important applications of salt in some industries:

  1. Pulp and Paper Industry: During pulp production, salt aids in the decomposition of cellulose fibers. In addition, it helps to adjust the pH level by using it in the neutralization process and to convert the pulp into paper with the desired properties.

  2. Textiles: Salt is an ingredient used in the leather processing process. Salt water baths are used to soften the skins. It is also used for finishing and preparing wool and cotton for dyeing and bleaching, and for removing acidity in the production of rayon.

  3. Waste and Water Treatment: Salt is a widely used material in waste and water treatment plants. In the reverse osmosis process, which is especially used for the purification of salt water, salt is used to increase the working efficiency of the membrane.

  4. Petroleum Additives: In the petroleum industry, salt is used for various purposes during the production, processing and refining of oil and natural gas. Salt increases the efficiency of production by using it in dissolving, precipitation and separation processes.

  5. Dye and Intermediate Compounds: Salt is used in the production of some dyes. Salt increases the dispersion of paint pigments and ensures a homogeneous mixture. It can also be used to adjust the viscosity of paints.

  6. Pharmaceuticals: Salt is an important ingredient used in the manufacture of pharmaceutical products and in treatment. Salt containing sodium and chloride is necessary to maintain the electrolyte balance of the body and to regulate the hormonal systems. In some medical conditions, salt therapy is applied to maintain the body's electrolyte balance. It can also be used as an additive in pharmaceutical products.
