PERSPECTIVES OF MEMBRANE BIOREACTORS FOR WASTEWATER PURIFICATION FROM WASTE OF PHARMACEUTICAL PRODUCTS AND BIOGENIC ELEMENTS

The article analyzes modern methods of wastewater treatment from bioresistant pharmaceutical products and biogenic elements. Pharmaceuticals, such as anti-inflammatory drugs, analgesics, antibiotics, narcotic drugs, hormones, drugs that reduce cholesterol,etc., are often get into sewage in small quantities. They are hardly biodegradable and, passing through wastewater treatment plants without any changes, they often end up in water bodies. They have significant negative impact on aquatic ecosystems and human health, while being present in open waters even in small quantities. Among the nutrients that are also present in the wastewater, nitrogen and phosphorus compounds deserve the greatest attention. While getting into water bodies, they cause eutrophication, which isalso dangerous to ecosystems and human beings. It is shown that among modern variety of purification methods, the most suitable for removal of pharmaceutical products and biogenic elements are biochemical methods and photopurification technologies, as well as using membrane bioreactors. Biosorption-membrane methods open the possibility to use modern biotechnologies for efficient removal of bioresistant xenobiotics and reducing their negative impact on natural environment. Using photopurification technologies can help to reduce amount of nutrients discharged in surface water bodies, thus reducing their potential for eutrophication, as well as receiving additional renewable energy sources.
