Antibiotic Pharmaceutical Wastewater Case Study
Treatment of Antibiotic Pharmaceutical Wastewater Using a Rotating Biological Contactor
One of the treatment of the wastewater is the treatment of antibiotic pharmaceutical wastewater using a rotating biological contactor. For your information, Rotating Biological Contactors (RBC) are effective for treating wastewater, while they are rarely reported to be used for treating antibiotic pharmaceutical wastewater (APW). Next, the biological treatment processes have been widely used in wastewater treatment for their low cost and effectiveness. The antibiotics in wastewater are of particular concern, as they can induce bacterial resistance, even at low concentrations. The activated sludge method is used mostly as an aerobic suspended growth process …show more content…
Later, it has been found that the biomass composition of the discs within the RBC plays a major role in the organic biodegradation. A high-strength antibiotic pharmaceutical residual liquid was mixed with ordinary wastewater and was then treated by a simple three-stage RBC system. In addition, the influence of some process variables was examined RBC has the advantages of a high concentration of microorganisms in good living and reproducing status, high efficiency for degrading organic compounds, and high suitability for fluctuations in flow rate and organic concentration (Z. Chen, 2006). The treatment effect was quantified by measuring the removal of chemical oxygen demand (COD), 5-day biochemical oxygen demand (BOD5) and ammonia nitrogen (-N).Then, the RBC also has the advantages of simultaneous nitrification and denitrification accompanied by carbon removal, low water content in the sludge making it easy to settle, easy operation, low energy consumption. Moreover, the antibiotics residual in waste streams poses a great threat to receiving water bodies such as streams, rivers, and ocean. The by-products of antibiotics manufacturing and residual waste liquid are a …show more content…
The steel industry is one of the most important and vital industry of the present and the future. Then, it contains many dissolved, undisclosed substances and chemicals in the wastewater. The steel industries produce wastewater and sludge during different industrial processes. Next, all these plants use a tremendous amount of water to cool the products and flush the impurities away from the finished stock The whole technologies for treating industrial wastewater can be divided into four categories chemical, physical, biological and mathematical methods. Technologies used in steel plants include cooling Tower, DM Plant, STP and river water treatment For your information, the physical treatment methods are including the sedimentation, stripping, ion-exchange, adsorption, floatation, filtering and other processes that accomplish removal of dissolved and undisclosed substances without necessarily changing their chemical structure. The wastewater Treatment Plant (WWTP or STP) possesses conventional methods like primary treatment, secondary treatment and tertiary treatment followed by ozonation method. Later, for the river water treatment which contains preozonation, flocculation, chlorination filtration / aeration, adsorption and pH correction processes was done. Recycling of wastewater is a mechanical process, which includes purification of wastewater up to the standard in a separate lagoon
