water to improve the water quality in Yangjae stream. Due to the system, the water quality improved from level 5 to level 2~3 and this plays an important role in restoring the ecosystem.
Secondly, vegetation revetment technique was used to make close-to-nature river bank. Concrete was removed from the shore and riverbank and stones, trees and other plants replaced the place instead.
Thirdly,
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 decreasing process and cost are studied from a few researchers. So we will show the whole process of the production
2000 B.C - The first recorded (The Susruta Samhita, Sanskrit writing) waterpurification 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 sand and course gravel.
A major step in the development of desalination technologies came in the 1940s during World War II when various m
about 10-15 percent higher methane (CH4) content than normal landfill gas.
Amount of organic waste is approximately 8,300tons/year by 2008 and 2007, among which only about 7% (6.1million tons/year) are used to source of energy (biogas).
Bio-gas produced by using organic waste were used mostly as a heating fuel of the digestion tanks or power plant fuel.
