Development of wastewater treatment technology with purpose of their reuse in process of obtaining cotton pulp

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 especially relevant Republics Central Asia. Also, development production pulp would provide acute shortage and paper, protect environment, reduce energy costs, chemical rationally available raw materials. The paper presents results studies on possibility cleaning waste liquor wash reuse in obtaining cellulose. object study cooking solution, spent liquor, used after pulping washing, their sanitary characteristics, quality indicators products obtained. discoloration wastewater, residual amount sodium hydroxide, change optical density composition washing were experimentally studied.
