Of ethanol as biomass energy, fuel and clean Can burn. Reduce the problem of air pollution and global warming issues produced from raw materials derived from agricultural crops, category 3 material is sugar (cane sugar, water, molasses, and beat out) of raw materials, type of starch (tapioca, potatoes and grains) and raw materials from agricultural by-products category (bagasse. Corn cob and straw) ethanol production process, waste water, which has caused a feeling of b o good and high formaldehyde. Approximately 40000-70000 mg per liter, and 100000-150000 mg per liter, respectively. Is the concentration of nitrogen and phosphates high. There are dark brown to black. And affect the quality views of the water source. Causes the intensity of the light that shines through the amount of oxygen into the water and from the air diffuses into the water source. As a result, the number of aquatic biodiversity and changed. So it can not discharge public.Color removal of wastewater can be used both in the process of physical, chemical, biological and physical methods include activated charcoal adsorption from prepared wood sawdust and coconut shell, which is a material with high porosity. Has the ability to absorb the paint color can be eliminated and the colors appear more efficiently, but it often happens that the blockage problem of facial skin layer of charcoal and reuse that also have high expenses. Substances through membranes (Electrodialysis) power is the easiest but often the issue occurs, the scale filter makes it stick to the electrical and power consumption must be cleaned frequently, so it is not a popular method of chemical coagulation and flocculation, such as using alum. Lime and iron compounds is another highly effective method, but there will be plenty happening sludge. Need to find how to make a sludge disposal or use of the ozone that must control the pressure, pH and temperature on the production of ozone in the system, thus making the electric power consumption. Affect the organisms in the water and biological methods are used in the treatment of waste, such as watercolor, color by absorbing algae found to be effective in the treatment of color. Energy-saving and low cost. Do not add chemicals into the environment, but there are restrictions on pH, temperature, nutrients and bacteria inhibitor use is an effective method, but there is a limit of, the bacterium is resistant not be toxic at higher concentrations. While the use of fungi. There is little restriction over the appropriate durability so bacteria that will bring color therapy. This ability to have semen in treatment applied watercolor Rama waste coming from the ethanol production plant. The use of microorganism in the treatment using cell color can be independent or freezing cells. When comparing the cell is freedom found the leak problem and the blockage of the cells, while cells that are effective in the treatment of peg colors and found no leak or blockage of the cell by cell immobilization technique commonly used is the Entrapment methods can be used with all types of cells, but.There are also restrictions on the number of cells per beads (Bead) and cell leakage problem is Encapsulation method, there are no restrictions on the number of beads per cell, but there are problems with granular cell freezing problem b ดอ่อนแอ from Entrapment and Encapsulation method by making education and developed a new method of cell fixation using the two methods together is to freeze the cells by hybrid technique (Hybrid Immobilization) tablets with high performance b. There are no restrictions on the number of beads per cell, and the cell can prevent problems from leaking well.
