The recent studies regarding the membrane technologies indicate that the membrane process applications involve for providing the high quality drinking water and increasing the use of industrial water consumption. The membrane process has been used in applications such as wastewater treatment, industrial water production, water softening, and in the separation of compounds having different molecular weights. Of using in many membrane process Microfiltration (MF) and Ultra filtration (UF) are low pressure filtration processes that are used for pathogen and suspended solids removal as seen in many studies (Guo et al., 2010; Yang et al., 2014). In this study, we investigated the possibility of using microfiltration (MF) and ultrafiltration (UF) membrane systems for treatment of wastewater generated from underground hard coal mining of Kozlu Basin. In first stage of this study, the wastewater was treated using MF membrane filtration system. The MF membrane filtration system was composed of the flat sheet MF membrane module equipped with Polivinilflorid (PVDF) membranes purchased from MICRODYN-NADIR membranes, Germany. The MF membrane has a filter area of 140 cm2 and average pore diameter of 0.2 μm as given by supplier. In second stage of study, the effluents of MF were treated using UF membrane filtration. The UF membrane filtration system was composed of the flat sheet UF membrane module equipped with Polyethersulfone (PESH) membranes purchased from MICRODYN-NADIR membranes, Germany. The UF membrane has a filter area of 140 cm2 and molecular weight cut-offs (MWCOs) of 50 KDa as given by supplier. In the experimental study, the raw water was provided from discharge point of underground hard coal mining of Kozlu Basin. In order to determine the total treatment performance of the MF/UF system, water samples were taken from inlets and outlets of the MF and UF membrane systems, respectively. The pressures were fixed at 1 and 2.5 bars for MF and UF, respectively during the experimental study. In test of wastewater, total coliform, turbidity, conductivity, pH, nitrite, nitrate, phosphate, sulphate, sodium, potassium, chemical oxygen demand (COD), total suspended solids (TSS), calcium, magnesium and total hardness as parameters were analysed in raw and treated water. The results were compared with Turkish Standards (TS 266) and European Union (EC).
