  • Is water reusable during a marble cutting process?
  • The reusability of the water during the process was also investigated. In the marble mines where the study was carried out, an average of 25 m 3 /day of water is used as the process water for cutting operations. It is thought that ~ 10 m 3 /day of this water is evaporated or remains between the marble blocks.
  • Can marble processing wastewater be treated by coagulation-flocculation process?
  • In the first part of this study, the treatability of marble processing wastewater by the coagulation-flocculation process was investigated.
  • Can water be reusable after sedimentation process in marble mines?
  • In this study, wastewater formed in marble mines operated as open mines with the aid of a cutting slope in the soil clarification tanks, which were made impermeable by using membranes and similar impermeable elements, was collected after the sedimentation process. The reusability of the water during the process was also investigated.
  • Are marble filtration and sodium silicate water treatment effective?
  • 5. Conclusion The present study confirmed that marble filtration as well as sodium silicate water treatment can be an effective, low cost and robust alternative for hatcheries facing elevated levels of Al and Cu in their inlet waters.
