Conduct of sludge from wastewater treatment of milk production transform of fuel case study : frieslandcampina fresh (Thailand) co.,ltd
This study was experimental study that had the propose to investigate the possibility of using sludge from wastewater treatment of milk production in case study of Friesland Campina Fresh (Thailand) Co Ltd. This study to investigate suitable ratio in making briquette between sludge and banana peel in ratio 95 : 5 75 : 25 50 : 50 25 : 75 and 5 : 95 by weights and analysis of compressed char were Moisture content Ash content Volatile matters Fixed carbon and Calorific value. The result of this study we found that sludge mixed with banana peel at the ratio of 25 : 75 had Moisture content 9.7 percent Ash content 15.8 percent Volatile matters 61.8 percent Fixed carbon 9.7 percent and Colorific mean 4195 kcal per kg. It can also be used briquette fuel substitutes of firewood in order to conserve the forest resources.
System design gio gasifier from food waste catalyst from pigeon feces and pig feces underanaerobic conditions
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
The development of ethanol fermentation of jackfruit wastes by a medium size distillation machine
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.
ระดับการเตรียมความพร้อมด้านสมรรถนะนักบัญชีไทย ความสามารถในการปรับตัว และความสำเร็จในวิชาชีพบัญชีหลังเข้าสู่ประชาคมเศรษฐกิจอาเซียน
This research aimed to study 1) the preparation level of Thai Accountant Competencies and adaptation capabilities; and 2) Factor affecting on success in accounting profession after The Asian Economic Community. The samples consisted of 400 accountant which implement in many businesses. Data collected by using online questionnaire and employed convenience Sampling. Descriptive Statistics were used such as percentage Mean ( X ) S.D. and ranking. Pearson Correlation and Multiple Regression Analysis were also employed to analyze data. The finding results explained that most of antecedents were female finished bachelor degree of accounting and has experiences average equal 7.51 years (S.D. = 6.723). In their views They thought that accountants preparation level competencies especially improvement of knowledge and skills of professional accountant were rather than fair well ( X = 3.9129; S.D. = 0.44034) as same as adaptation capabilities ( X = 3.79; S.D. = 0.46631). Pearson Correlation was between 0.381 – 0.739 at the significance level α < 0.01. This findings also explained that the preparation level of Thai Accountant Competencies accounting experience attitude of implement accounting and adaptation capabilities have positive significance level at confidence level 99 percent (α < 0.01).
