The purposes of this experimental project are learning and comparing the result of the Vetiver confine time and the health of the plants in the community waste water. The waste water of this experimental are collected from the low-cost housing project Bang-Kruay (Pha-ngung Temple) in Prai Bang sub district Bang Kruay district Nonthaburi province. The experimentation of this project was built the 2 potholes. The first pothole was set by grow up the Songkha 3 Vetiver with the floating platform and the Songkha 3 Vetiver while the second set had only the floating platform without plants as a control. However both of the potholes were control the lead time of confine the Vetiver on 7 14 and 21 days. Parameters of this project are BOD SS nitrogen and the phosphorus. The result showed that the pothole with the Songkha 3 Vetiver was effective more than the pothole that without the Vetiver. The best lead time of confine is 7 days and the performance of BOD SS nitrogen and phosphorus are 83.32 80.31 78.88 and 76.55 that calculated in percentage. Moreover during the test process the Songkha 3 Vetiver are treated and had the survival in 100% well grew up had the new spires roots and the leaves. The waste water was on clear less sediment no foul odor. The Songkha 3 Vetiver was effectively for the community waste water treatment with the floating plat form. From the result it can be treat the BOD and SS till 14 days the

Educational system designed to produce Biogas from food waste. By comparing the quality of pigeon dung. And the value of the pig was used as the catalyst. In anaerobic conditions. Purpose was to compare the quality. And the amount of gas from the two types of catalyst used and the process of building a compost bin for households in the city. Which places the living repository of materials Rajamangala University of Technology PhraNakhon. Bangkok campus as a place of experimentation. The fermentation process is used for the same condition is temperature materials and processes in each trial which takes a total of 60 days separated by a period of preparation. During the experiment. And at the conclusion of the experiment. The 10-day period of preparation for the trial and during the 40 days of the conclusion of the 10-day trial that the mixed infection. And rubbish food for 10 days to wait for an extended amount of infected nodes Jane Mehta. The index values are measured. System including temperature fermentation - acid alkaline VOCs. Hydrogen sulfide oxygen carbon monoxide and methane gas in the range 12.00 pm - 13.00 pm every day for 30 days The result was the conclusion that Swine manure fermentation properties of methane higher than the pigeons in 3: 1 can be seen from the measurement equipment and systems. The odor is caused by the pigeons is very low and almost no odor. When compared to the after-fermentation of swine manure to 19 days while the smell of fermentation of swine manure odor remains

A Comparison Efficiency of Cafeteria Wastewater Treatment with EM Produced by Banana Watermelon and Guava Case Study : Rajamangala University of Technology Phra Nakhon Cafeteria ( North Bangkok Campus) has the objective to compare the efficiency of wastewater treatment by using the EM microbe for the Cafeteria that has no waste water treatment system. The treatment solution was leavening agent EM : Molasses : Fruits : Water in the ratio 1 : 1 : 2 : 20 liters (as an experimental group) and leavening agent EM : Molasses : Water in the ratio 1 : 2 : 20 liters (as a control group). respectively and mixed each solution set in wastewater treatment ratio of 1 : 1000 (EM 1 part : wastewater 1000 part) . In the experiment use the 10 liters of wastewater sampling and added the EM microbe solution every 3 days 10 ml per a day and daily for 3 weeks. Collecting the wastewater every 7 day. Parameters in this experiment are BOD COD SS Oil and Grease pH Color and Odor. The comparison showed that the EM made from watermelon can reduce the BOD and SS of wastewater is the best. And adapt the most of pH to pH 7. The EM make from guava can reduce the COD Oil and Grease is the best. The results were in the standards of sewage release of the building type B. In the 1st 2nd and 3rd week the BOD COD SS Oil and Grease and pH from the waste water treatment with EM microbe that make from Banana Watermelon and Guava ( as a Experimental group) and molasses (as a Control group) only are statistically different at the .05 level. By the way the Color and Odor of the waste water analysis before and after treatment with EM microbe 4 species still have yellow color and bad smell.

The development of ethanol fermentation of jackfruit wastes by a medium size distillation machine aimed to study and develop an ethanol fermentation method that gives optimal production of ethanol. In this research the ethanol production capability of 4 different groups of microorganisms including natural microbes microorganisms in stock rice fermented Saccharomyces cerevisiae EDV 492 and S. cerevisiae EC 118 is compared. The following procedure was implemented to allow the prescribed comparison: 1) microbes culturing (350 ml) for a total period of 20 days. Based on the study results all four groups of microorganism were capable of growing in the given culture medium which is sugar substrate. 2) Small sized fermentation (1 liter) for a total period of 4 days. From this second procedure it can be discovered that microorganism in stock rice fermented and S. cerevisiae EC 118 were highly efficient in producing sugar and ethanol 14% and 13% (v/v) respectively. 3) Develop small sized fermentation to a medium sized fermentation (20 liters) by fermenting natural microbes for a total period of 4 weeks until sugar is obtained. According to the study glucose must be added to increase the sugar level up to 25% Brix in order to provide sufficient substrate to allow ethanol production of the studied microorganisms. During ethanol fermentation process it can be found that microorganisms in stock rice fermented and S. cerevisiae EC 118 produced the highest amount of ethanol at 16% (v/v) within the period of 10 days and 8 days respectively. Hence according to this development of ethanol fermentation S. cerevisiae EC 118 is the most efficient microorganism in terms of ethanol fermentation of jackfruit wastes. In addition after the distillation of 99% ethanol it can also be found that both microorganisms in stock rice fermented and S. cerevisiae EC 118 produced 720 ml and 740 ml of ethanol respectively.
