RESEARCHES ON BIOMEMBRANE PURIFICATION AND DEMINERALIZATION OF WASTE WATERS AT SYZRAN OIL REFINERY
2012
There are given the research results of biomembrane waste water purification at Syzran Oil Refinery and demineralization of biologically treated sewage waters by the method of reversible electrodialysis. We compared the purification efficiency on the membrane bioreactor with ethanol dosing (in order to get deeper denitrification) and without it and the purification without adding household drain as well. It is shown that biomembrane technology combined with sorption tertiary treatment makes it possible to meet the requirements of the Russian Federation norms to the quality of treated sewage. The results of the experiment on the demineralization of biologically treated sewage waters using the method of reversible electrodialysis are given. We have concluded that the recycle systems of the plant can be fed with demineralised desalted water.
