Available in PDF, EPUB and Kindle. Book excerpt: Copper in sewage sludge is regulated under the land application regulations by the United States Environmental Protection Agency (USEPA) in 1994. To comply with EPA regulations, Penn State University has been sending their sewage sludge to a landfill due to high copper concentrations for the past 30 years. A previous study indicates that the main source of copper was the corrosion of copper in the Universitys steam heating systems. The copper in condensates were captured by the ion exchange softening process and released into the university sanitary sewer systems through the waste brine solution. This study focused on removing dissolved copper from synthetic water samples and actual waste brine solutions which generated from Penn State Universitys Steam Plant. To aid in copper removal, a lab scale electrowinning process was constructed. At first, synthetic water samples were prepared for the test had similar copper concentration as the actual waste brine solution. Various levels (0 4 M) of sodium chloride were evaluated in this study. The results indicated that the concentration of sodium chloride plays a major role in copper removal. More than 90% of copper reduction could be achieved after three hours of reaction at an appropriate salt concentration (0.04 1.5 M). Several electrochemical parameters, distance between electrodes and the voltage applied into the system, were studied and verified. Both of them play important roles in copper removal. A significant positive correlation existed between voltage and maximum copper reduction. Current efficiency decreases with increasing time of electrowinning, and it is low, only 14 23%. Two types of internal circulation reactors were constructed for copper electrowinning test. One has three square plate electrodes, two for anodes, one for cathode. Another use aluminum or titanium/platinum alloy basket electrode as cathode, anode still use graphite rod electrode. The copper remove efficiency for both reactors lower than 55% and some blue flocs were precipitated out. A bench scale test using batch reactor was conducted using actual waste brine solutions collected at University East Steam Plant. Around 50% of copper reduction achieved after three hours of reaction, which is much lower than the remove efficiency of synthetic water. 85% of copper reduction achieved after three hours of reaction, with high initial copper concentration (221 mg/L). High salt concentration (2.0 2.5M) and low copper concentration of actual waste brine water (6.5 63.5 mg/L) are likely the reasons. The extracted copper did not stick to the electrode very well, but those copper can be removed completely using a bag filter. This research will provide us with a better understanding of the process of copper removal by electrowinning process in wastewater treatment and assist Penn State University in complying with the rules of land application.

Book Synopsis Copper Removal Using Ion Exchanger Flat Sheet Mixed Matrix Membrane by : Fong Fong Kiew
Download or read book Copper Removal Using Ion Exchanger Flat Sheet Mixed Matrix Membrane written by Fong Fong Kiew and published by . This book was released on 2015 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ion exchanger has been widely used and applied in removal of heavy metal in wastewater treatment. In the current study, mixed matrix membrane (MMM) ion exchanger was developed by incorporating Amberlite IR120H into polyethersulfone (PES) dope polymer solution for copper removal. The effect of PES composition in dope polymer solution was varied from 23wt%, 25wt%, 28wt% and 30wt% at constant amount of 20g Amberlite IR120. The performance of membrane was evaluated using batch binding and cross flow filtration. In batch binding, the highest static binding capacity of the copper removal was achieved by membrane prepared from 30wt% PES with the binding efficiency at a value of 64% from 500ppm standard solution of copper (II) sulphate pentahydrate. In cross flow filtration, 30wt% PES membrane has the maximum binding efficiency at 95%. Regeneration study was studied with 30w%t PES membrane using 10%HCL elution solution in three consecutives running cycle. The membrane can be regenerated with 97% binding efficiency in each 3 cycles meaning all the membrane produced can be regenerated. As a conclusion, the higher the composition of PES membrane, the higher the adsorptive performance, thus 30wt% PES membrane was the optimum PES composition.

Available in PDF, EPUB and Kindle. Book excerpt: To protect stream organisms in an ephemeral stream at the Savannah River Site, a proposed National Pollutant Discharge Elimination System (NPDES) permit reduced the copper limit from 25 [mu]g/l to 6 [mu]g/l at Outfall H-12. Efforts to reduce copper in the wastewater and stormwater draining to this outfall did not succeed in bringing copper levels below this limit. Numerous treatment methods were considered, including traditional methods such as ion exchange and natural treatment alternatives such as constructed wetlands and peat beds, all of which act to remove copper. However, the very low target metal concentration and highly variable outfall conditions presented a significant challenge for these treatment technologies. In addition, costs and energy use for most of these alternatives were high and secondary wastes would be generated. The Savannah River National Laboratory developed an entirely new 'detoxification' approach to treat the outfall water. This simple, lower-cost detoxification system amends outfall water with natural organic matter to bind up to 25 [mu]g/l copper rather than remove it, thereby mitigating its toxicity and protecting the sensitive species in the ecosystem. The amendments are OMRI (Organic Materials Review Institute) certified commercial products that are naturally rich in humic acids and are commonly used in organic farming.
