Waste from Water Softening Stations for Treatment Wastewater Containing Dyes

In the general balance of water consumption, a considerable part falls on softened water. The processes of obtaining softened water form a significant amount of liquid waste containing calcium and magnesium salts. We show the possibility of using wastewater from water softening installations for the treatment of wastewater containing dyes. The obtained results demonstrate high efficiency of wastewater treatment in textile factories. An additional advantage of the use of sewage water softening plants is the economy of reagents for the removal of dyes.
