Wastewater Treatment of a Denim Washing Plant by Using Waste Pumice Stones to Recycle Wastewater and Reuse

Abstract

In this study, the removal of pollutants from the wastewater of a denim washing plant by using the waste pumice stones and reuse of treated water were targeted. The trials were carried out through a continuous adsorption system. For this aim, the waste pumice stones were placed into an adsorption column, and the wastewater was allowed to pass through the column in different flow rates. The treated water was mixed with freshwater in certain ratios in order to be reused in laundry. The result of the studies revealed that the treated water has the potential to be used as denim washing input water.
