| Title : | MEMBRANE TREATMENT OF WASTE WATER FROM THE HYDRODISTILLATION OF OIL-BEARING ROSES |
| Abstract : | Bulgarian rose oil is world famous for its high quality. Obtaining it makes the cultivation and processing of oil-bearing rose crops an important agricultural branch. There are more than 200 species of roses in the world, and in Bulgaria the species with the greatest agricultural importance are Rosa damascena Mill. f. trigintipetala Dieck. and Rosa alba L. Their qualitative composition is relatively constant and includes, in addition to essential oil, a variety of polyphenols, vitamins, and minerals. Products from the processing of the rose flower are: rose oil, rose absolute, rose concrete, rose water and others from secondary processing. Hydrodistillation is the technological method for obtaining rose oil, but it generated huge amount of biocontaminated wastewater. The retention of the organic components will satisfy the ecological criteria for the purity of wastewater and will create an opportunity for full-fledged use of their bioactive properties. The developed conventional methods are not sufficiently precise, cost-effective and environmentally friendly. Membrane technology and ultrafiltration processes have proven their technological and economic efficiency for purification, separation, concentration and decontamination of various liquid products. The aim of the study is to investigate the possibility of applying composite polyacrylonitrile membranes for the purification of wastewater from the hydrodistillation of oil rose flower and separated into the waste components. The membranes used were found to remove more than 60% of total organics and separate more than 70% of polyphenolic compounds. |
