The Application Of Coagulants And Adsorbents For Textile Production Waste Water Purification

Abstract

Wastewater from the textile industry is highly complex and highly toxic and poses a serious environmental hazard. Wastewater treatment in textile production is a multi-stage process that requires correct step-by-step processing, since textile auxiliary substances can be toxic. The effective conditions for the sorption of the dye from an aqueous solution selected by the sorbent have been determined. It was found that the effective mass of the sorbent is within 0,2; 0,3; 0,4; 0,5; 0,6 g per 100 ml of solution. The regularities of the dependence of the adsorbent mass in the process of removing an active dye of various types from the solution on the optical density have been revealed. It was found that an increase in mass significantly increases the purification of the solution from the dye, and leads to a decrease in the optical density at the points corresponding to 0,4 and 0,6 g. At the same time, it was determined that the maximum (up to 97%) wastewater treatment from surfactants and dyes by a chemical method when using the composition K-5 and K-6 is achieved with a particle size of sorbents of 0,5-0,6 nm.
