2000 B.C - The first recorded (The Susruta Samhita, Sanskrit writing) water purification began with the Egyptians. It is said that impure water should be boiled over a fire, heated in the sun, have a hot iron dipped into it or purified by filtration through sandand course gravel.
A major step in the development of desalination technologies came in the 1940s during World War II when various m
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 process focused on starch storage in algae cultivation and fermentation process.
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.
and separation processes, heat exchangers, and heat storage media. Design aspects and safety are also important for high-temperature processes.
-Thermo-chemical water splitting
For example, Thermo-chemical water splitting is the conversion of water into hydrogen and oxygen by a series of thermally driven chemical reactions. Thermo-chemical water-splitting cycles have been known for the past

Gorosoe is only famous in the place where Gorosoe is produced. Gorosoe tree grow naturally Baek-woon Mt, Ji-ri Mt and Gangwon state. In Jeonranam state, people collect fluid of Gorosoe tree and use it as medical waterand it is one of the important income sources. Because of recent interest for health food is increasing, interest for Gorosoe is also increasing. And the prospect
