EFFECT OF THE CONTACT ANGEL ON THE EFFECTIVENESS OF MYCOESTROGENS REMOVAL FROM WATER USING NANOFILTRATION MEMBRANES

The research addressed the removal of selected mycoestrogens by nanofiltration using membranes different in membrane casting polymers, degree of NaCl removal and efficiency. It also determined the effect of hydrophobicity of a membrane characterized by the measurement of contact angle on micropollutants retention. The tests were carried out on a new membrane and one modified by inorganic and organic matter. The membrane prepared from cellulose acetate CK characterized by a high contact angle and NaCl removal yielded the highest mycoestrogens retention. The presence of inorganic and organic matter in water reduced membrane efficiency and increased hydrophobicity due to the modification of the membrane surface. Those filtration conditions brought about a change in micropollutants retention.
