Kâğıt atıksularından bütünleşik membran sistemi ile su geri kazanımı ve konsantre atık minimizasyonu

Abstract

This study aimed to minimize the concentration obtained after the concentrate flow resulting from continuous operation of the NFloose/NFtight membrane filtration is treated through a hybrid Advanced Oxidation (Fenton and photo-Fenton)/submerged UF processes. With the MPF-36/ESNA membrane filtration, 71 mg/L COD and 19 mg/L TOC values were obtained in the final effluent. The treatment of the resultant concentrate current with the IOP/submerged UF hybrid processes, it was observed that UVC-submerged UF process provided the best performance. TOC and COD values in the UF effluent were found to be close to the values of the raw paper wastewater used and it was determined that it could be fed to the NFloose input. Thus, while water recovery is ensured, it was also observed that the minimization of the membrane concentrate through hybrid process will achieve significant contributions to concentrate waste management.
