Abstract

Modern society demands industrial technology advances to produce products that have high durability and long utilization lives. Materials made from ferrous metal become a solution to meet these industry needs. Ferrous metal is corrosive and it requires more care to support the performance. Electroplating or metal coating applied to iron or nickel solves this problem. In the production process, the usage of nickel is only 30%-40% and the remaining 60-70% is wasted through effluent. Nickel is a toxic heavy metal that can cause cancer. The purpose of this study is to evaluate the effect of iron concentration on nickel metal removal in electroplating wastewater using an insulated electrolytic reactor double chamber electrodeposition cell (DCEC). The result of this study shows that any ratio variation of iron concentration to nickel gives varying impacts on nickel removal efficiency, electric current efficiency, and specific energy. On the fourth variation, the iron ratio of 1.29% removed 83.1% nickel (the highest removal efficiency) at the cost of 20.687 kWh / kg specific energy. The number is extremely high for energy needs. On the other hand, the variation of iron ratio of 1.73% consumpting only 15.067 kWh / kg, the lowest specific energy needs, resulted in the lowest removal efficiency of 63.6%.

Abstract

Sulfonated polyether ether ketone (SPEEK) was utilized as a proton exchange membrane (PEM) in Microbial Fuel Cell (MFC). The SPEEK performance in producing electricity had been observed in MFC using wastewater and glucose as substrates. The MFC with catering and tofu wastewater produced maximum power density about 0.31 mW/m2 and 0.03 mW/m2, respectively, lower that of MFC with tapioca average power density of 39.4 W/m2 over 48 h. The power density boosted because of the presence of Saccharomyces cerevisiae as inoculum. The study using of S. cerevisiae and Acetobacter acetii, separately, were also conducted in with glucose as substrate. The MFC produced an average power densities were 7.3 and 6.4 mW/m2 for S. cerevisiae and A. acetii, respectively. The results of this study indicated that SPEEK membrane has the potential usage in MFCs and can substitute the commercial membrane, Nafion.Article History: Received: Juni 14th 2017; Received: Sept 25th 2017; Accepted: December 16th 2017; Available onlineHow to Cite This Article: Putra, H.E., Permana, D and Djaenudin, D.
