TREATABILITY OF OLIVE OIL MILL WASTEWATER WITH ULTRAFILTRATION AND NANOFILTRATION MEMBRANES

Abstract

In this study, the membrane filtration of pretreated olive oil mill wastewater was investigated by using three membranes. Two of membranes used were ultrafiltration membranes (JW and MW membranes) and the other one was nanofiltration membrane (DK membrane). The effects of main operating parameters (transmembrane pressure, feed flow rate and membrane type) on the permeate flux and membrane fouling were examined. The highest permeate flux were obtained with the MW membrane with Qf=200 l/h flow rate and TMP=4 bar, while the highest removal efficienciess were obtained with the DK membrane. COD, TOC, SS, oil and grease concentrations of DK membrane effluent were 1600 mg/l, 948 mg/l, 40 mg/l, 80 mg/l, respectively

ZEYTİNYAĞI ENDÜSTRİSİ ATIKSULARININ ULTRAFİLTRASYON VE NANOFİLTRASYON MEMBRANLARIYLA ARITILABİLİRLİĞİ

Abstract

Bu çalışma kapsamında, ön arıtılmış karasu numunesinin membran filtrasyon ile arıtılabilirliği incelenmiştir. Deneysel çalışmalarda, iki ayrı ultrafiltrasyon membranı (JW ve MW membranı) ve bir nanofiltrasyon membranı (DK membranı) kullanılmıştır. Basınç, besleme debisi ve membran tipinin süzüntü akısı ve membran kirlenmesine olan etkileri çalışma kapsamında incelenmiştir. En yüksek süzüntü akısı MW membranı ile 200 l/sa debide ve 4 bar basınçta elde edilirken, en yüksek giderme verimlerine DK membranının kullanımıyla ulaşılmıştır. DK membranı ile elde edilen KOİ, TOK; AKM, yağ ve gres konsantrasyonları sırasıyla 1600 mg/l, 948 mg/l, 40 mg/l, 80 mg/l’dir
