Özet

The water consumption in textile industry, especially in dyeing and washing processes is too high. Therefore, large amount of wastewater is produced and discharged to the receiving environment during textile production process. Discharge of colored effluents without decoloration originated from textile industries may cause serious problems in the receiving environments. Besides water resources are limited. The textile industry should look for recycling and reusing this water. The objective of this chapter is to explain the use of various natural materials like basaltic tephra and clinoptilolite to remove basic, acidic and reactive types of dyes from textile wastewater. The determination of dye removing capacities and adsorption isotherms of these adsorbents are among the objectives of this study.
