Examination and Evaluation of a Metal Industry Wastewater Treatment and Recycle

Abstract

Discharge of industrial wastewater into the environment without being subjected to proper treatment results in both reduction of resources and damage to the environment and destruction of biological diversity. In addition, treatment and reuse of industrial wastewater as a measure to consume clean water resources will reduce water consumption and at the same time remove oil, grease, alkali, acids and toxic substances from wastewater and discharge the wastewater to the environment will prevent contamination of water resources. In addition, recovery and reuse of waste water is an advantage. As is known, leaving the industrial wastewater to the environment without treatment causes some problems in the biological environment. For example, wastewater containing harmful chemicals damages living organisms in the aquatic environment and living organisms in the ground. Accordingly, in sand filtration, active carbons, ultrafiltration, and reverse osmosis units, chloride and COD removal efficiencies are compared to the water quality in the main promoting pipe.
