treatment process - saccharification. Then, it can be changed ethanol form through fermentation by yeast or genetically engineered E.coli and we can produce biofuel from that ethanol. Now, the way of decreasing process and cost are studied from a few researchers. So we will show the whole process of the production of bioethanol from algae, and we suggest some solutions for reducing cost and the p
wastewater and recycled activated sludge are introduced typically at several points in the aeration tank. The organic load on the aeration tank, MLSS concentration, and oxygen demand are uniform throughout the tank. An advantage of the CMAS process is the dilution of shock loads that occur in the treatment of industrial wastewaters. The CMAS process is relatively simple to operate but tends to ha

waste of money to invest in temporary residential areas because of Korea's physical geography. Many evident circumstances, however, prove that Korea is never safe from natural disasters.
A typhoon is needless to point out. A typhoon forms over the northwestern part of the North Pacific, and 23 typhoons on the average move northward and arrive at Korea. Especially, the typhoons "Rusa" and "Maemi"
