treatment and fermentation process, After algae produce sugar or starch from carbon dioxide, sunlight and water, those free complex carbohydrates turned into fermentable sources through pre-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 decreasin
water 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 have lo
and society meet a range of energy and environmental challenges.
One example can be found in the area of water use and purification, where GE scientists are investigating new membrane materials and innovative advanced separation technologies. These allow for further treatment and better performance of on-site wastewater reuse and recycling for the industrial, agriculture and municipal sectors.
2. The Necessity of sustainability
The recent research show that it demands some expenses in the first stage. But when they pass through some point, it will bring the achievements of corporation.
First, the sustainability is a flow in this period that can not be ignored and the essential factor to compete in this field. The playstaion in Sony lost more than 200 million dollars when the Cadmium,
