The paper aimed to assess the quality of wastewater resulted from the water treatment plant of a porcelain factory from Alba Iulia. Two of our society’s biggest problems are water pollution and wasteful use of freshwater. Although industry is not the main user of water resources, it is the main responsible for water pollution. Monitoring of porcelain industry wastewater provided the information needed for the identification of water pollution problems. The following water quality indicators have been analyzed: pH, suspended solids, fixed residue, chemical oxygen demand (the dichromate method), calcium and aluminum. During the year 2012, the values of the analyzed indicators didn’t exceed the maximum admitted limits established by NTPA 001, except by suspended solids, which recorded higher values for all analyzed samples. In conclusion, the monitoring of the porcelain industry wastewater revealed the fact that the main pollutant generated by this economic activity is represented by suspended solids, whose removal requires additional water treatment methods.
