In the face of increasing water scarcity, the industrial wastewater reuse has become an important practice of improving water use efficiency. However, industrial wastewaters have very high pollution potential and industrial wastewater treatment is very challenging. Furthermore, new and emerging pollutants cannot be adequately removed by currently applied state-of-the-art methods. New technologies and a combination of biological and chemical treatment methods are urgently required. Hence, the objective of this chapter is to discuss the most adequate wastewater treatment methods from the studies dealing with the treatment and reuse for the wastewaters, coming from the dominant industries in Turkey: the textile, poultry slaughterhouses and olive processing industries. In the studies, membrane processes as well as physical biological, and conventional treatment methods were applied. The performance of ultrafiltration (UF) and nanofiltration (NF) membrane processes after aerobic and anaerobic pre-treatment for the textile wastewater was researched. The use of centrifugation as a pretreatment step for the UF, NF, and reverse osmosis (RO) membranes was performed for the poultry slaughterhouse wastewater with high particulate COD content. Finally, the effects of the application of UF, NF, and RO membranes after preliminary treatment with centrifugation for olive wastewater with high solids content was analyzed. |
