Kâğıt atıksularından bütünleşik membran sistemi ile su geri kazanımı ve konsantre atık minimizasyonu
Bu çalışmada, kağıt endüstrisi atıksularının NFgevşek/NFsıkı membran filtrasyonu ile sürekli işletimi sonucu oluşan konsantre akımın, hibrit İleri Oksidasyon (Fenton ve foto-Fenton)/batık UF prosesleri ile arıtılarak minimizasyonu hedeflenmiştir. MPF-36/ESNA membran filtrasyonu ile nihai çıkış suyunda 71 mg/L KOİ ve 19 mg/L TOK değerlerine ulaşılmıştır. Oluşan konsantrenin İOP/batık UF prosesleri ile arıtımında, en iyi performans UVC-batık UF prosesinde elde edilmiştir. UF çıkış suyu TOK ve KOİ değerlerinin, kullanılan ham kağıt atıksuyuna yakın değerlerde olduğu görülmüş ve NFgevşek girişine verilebileceği belirlenmiştir. Bu sayede, membran prosesler kullanılarak su geri kazanımı sağlanırken, membran konsantrelerininde hibrit proses ile minimizasyonu sonucunda konsantre yönetimine önemli katkılar sağlanabileceği görülmüştür.
Water recovery from pulp and paper mill wastewater with integrated membrane system and minimization of concentrated waste
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 photoFenton)/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.
