Today, an urgent problem is developing a technology for producing cotton cellulose from low-grade linters with the rational use of water resources. This issue is especially relevant for the Republics of Central Asia.
Also, the development of a technology for the production of cotton pulp would provide an acute shortage of pulp and paper, protect the environment, reduce energy costs, reduce water and chemical costs, and rationally use available raw materials.
The paper presents the results of studies on the possibility of cleaning waste liquor and wash water for reuse in obtaining cotton cellulose. The object of the study is the cooking solution, spent liquor, used water after pulping and washing, their sanitary characteristics, and the quality indicators of the products obtained.
The discoloration of wastewater, the residual amount of sodium hydroxide, the change in the optical density of the cooking solution, and the chemical composition of the waste liquor and washing water after discoloration were experimentally studied.
