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 low organic substrate concentrations(i.e., low F/M ratios)that encourage the growth of filamentous bacteria, causing sludge bulking problems.

water flow direction, inlet locates downside and outlet locates upside.
Through this, we can know that axial impeller is not suitable. Also, because of wide width of tank, it has poor mixing.
Second, there is a problem with chemicals. PAC is injected with Cl2, so activation of Cl2 must be restricted.
Also, using alum may cause settling.
Alum lowered pH in localized area. To overcome this
II. How is CBM formed
Coalbed methane (CH4) forms in one of two ways. During the earliest stage of coalification (the process that turns plant detritus into coal), biogenic methane is generated as a by-product of bacterial respiration. Aerobic bacteria (those that use oxygen in respiration) first metabolize any free oxygen left in the plant remains and the surrounding sediments. In fresh water
I. Background and the Purpose of the Project.
“A lack of water resources might bring more conflicts in near future. Soon, more and more conflicts concerned with water will be on surface.”
This phrase is quoted from the speech in ‘Davos World Economic Forum’ by Ki-Moon, Ban, UN Secretary General. The Issues concerned with water can be summarized in three large categories - deserti
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) 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 sand and course gravel.
A major step in the development of desalination technologies came in the 1940s during World War II when various m
