Abstract

The mainly objective of this research is assessment of the potential of Chachoengsao locality producing

water pollutant load. The factors affecting production of pollutant were considered i.e. 1) the locality producing high

water pollution load, 2) the locality containing high density of water pollutant sources, 3) the locality has highly

increasing rate of water pollution load, 4) the locality containing low quality of surface water and 5) the locality

locating nearby Bangpakong River.

The results can be concluded that Muang-Chachoengsao district performed the highest water pollution

load and the highest increasing rate of water pollution load. Bangpakong district contained the highest density of

water pollutant sources. Klong-Chabang, Klong-Banpho and Klong-Takhai, could be instant improved due to their

inferior water quality. The districts locating nearby Bangpakong River were Muang-Chachoengsao, Bangkhla, Bangnampriao, Bangpakong, Banpho and Khlong-Khuean. The first and the second localities performed huge

potential in water pollutant production were Muang-Chachoensao Municipality and Takhai Subdistrict Administrative

Abstract

The purposes of this research were to compare the different common factors with health care behaviors, and their relationships to the Health Belief Model with the health care behaviors of Burmese workers

in a factory in Samut Prakan province. The samples of this study were 300 Burmese workers with questionnaires were used as a data collection tool. that the results found that the most of sample were found

to be male, aged between 20 to 25, Buddhists and single. Their education background was primary school, , an income greater than expenses, no underlying diseases, having their spouse as the caretaker upon an illness. In

addition, when illness they chose to buy medicines from drugstores near their homes. Health beliefs of the

samples were found to be in the moderate levels with an average of 2.35. In regard to their health beliefs, the first was perceived benefits of illness prevention and treatment, followed by perceived seriousness of illness,

susceptibility to illness, health motivation and illness obstacles, respectively. Their health care behaviors were at low levels with an average of 2.30. In regard to health care behaviors, the first was food consumption and

drugs, followed by health checks, rest, environmental management, stress management and physical exercise. Conforming to the assumptions made, Burmese workers of different sexes, ages, religions and marital status

were have the different health-related behaviors. On the basis of the Health Belief Model, the perceived susceptibility to illness and perceived benefits of illness prevention and treatment have a positive relationship

with health care behaviors with .05 level of statistical significance.

Abstract

This research is an experimental research. The purpose of the research was to study the

cultivation factors, the obtained biomass production, the wastewater treatment efficiency, and the harvest biomass of Spirulina TISTR 8222. The study consisted of three parts such as 1) the cultivation by using of

medium contains organics (COD) in 120, 220, and 320 mg/L. 2) the testing of wastewater treatment by using of wastewater treatment model in open system and open-aerated system including four sub model types such as

the model of open-aerated with the additional of artificial light, the model of open system with the additional of artificial light, the model of open-aerated with the national light, and the model of open system with the national

light. The third part is the study of Spirulina biomass harvesting using Jar-test technique. From the results, it was found that the main factor for cultivation consisted of the light intensity in

the range of 3,620-3,980 lux without any requirement for carbon source, and it could be cultivated under room

temperature (26-30C). The result of carbon source addition in term of COD revealed that it did not help to

increase Spirulina biomass production. After 27 days of cultivation, the biomass production was achieved at 1,731, 1,996, and 1,637 mg/L with the growth rate of 52.0, 61.5, and 47.7 mg/L/d for the treatment of organics

containing in cultivated medium of 120, 220, and 320 mg/L, respectively. The amount of biomass production could be predicted after 5 days of cultivation by using linear equation. Moreover, the study of wastewater

treatment efficiency of Spirulina with the open and aerated-open treatment system showed that after 19 days of treatment using autoclaved wastewater, the COD removal of 80, 82, 87, and 83 percent, the TKN removal of

84, 91, 89, and 40 percent and the total phosphorus of 32, 38, 25, and 43 percent were achieved. For the

treatment using non autoclaved wastewater, the COD removal of 79, 78, 83, and 86 percent, the TKN removal of 85, 89, 80, and 51 percent and the total phosphorus of 31, 0, 0, and 22 percent were observed for the treatment

1-4, respectively. Nevertheless, the testing of precipitation by ferric chloride and alum for harvesting of biomass production of Spirulina indicated that the appropriated dose was 150 and 200 mg/L.

ABSTRACT

This research is an experimental research. The purpose of the research was to study the solid state fermentation conditions and the citric acid production from fruit wastes using Aspergillus niger TISTR 3063. The composition of the fruit wastes such as jack fruit

fiber, pineapple core, and watermelon shell was analyzed at the beginning of the experiment. The model of solid state fermentation of the studied fruit wastes was carried out consequently for studying of the obtained citric acid production together with the ferme ntation

conditions affecting to the citric acid production under solid state fermentation included the fermented temperature. From the results, it was found that the citric acid production from the fermentation of jack fruit fiber, watermelon shell, and

pineapple core of 28.64, 2.58, and 16.62 g/L, respectively were obtained under the fermented temperature of 40C. The maximum citric acid

production from jack fruit fiber fermentation was achieved within three days. While, the maximum production from watermelon shell and

pineapple core were achieved longer time within four days and five days. During fermentation process, the volatile fatty acids were observed such as formate, acetate, and butyrate, which produced in high amount from the fermentation of watermelon shell. Whereas, the

pH through fermentation process in each fermentated temperature was in the range of 3.66-6.82, 4.38-6.24, and 4.33-6.40 for jack fruit fiber fermentation, 4.17-6.80, 5.09-6.71, and 4.99-6.41 for watermelon shell fermentation, and 2.60-3.94, 3.39-6.20, and 3.68-5.38 for

pineapple core fermentation, respectively.

Abstract

This experimental research is focusing on 1) the comparison of treatment efficiency

between MBR and MBR-PAC and 2) the comparison of treatment efficiency between batch dose and continuous dose. The lab-scale experimental unit and synthetic textile wastewater were applied. The

experimental conditions consist of 1) MBR without PAC added, 2) MBR-PAC where PAC of 1,000 mg/L was added, 3) MBR-PAC where PAC of 2,000 mg/L was added and 4) PAC was continuously dosed into

the 3th reactor with PAC age of 50 days. It was found that, the addition of PAC improved COD removal efficiency. In case of MBR, MBR-PAC (1,000 mg/L) and MBR-PAC (2,000 mg/L), the treatment efficiencies were 87.42 (±9.14),

91.23 (±3.41) and 96.51 (±1.59), respectively. Moreover, in long-term, MBR-PAC (2,000 mg/L) performed higher color removal efficiency than MBR-PAC(1,000 mg/L) and MBR. The color removal

efficiencies were 74.99 (±6.04), 52.11 (±6.94) and 47.61 (±8.40) %. In case of continuous dose with PAC age of 50 days, the treatment efficiency was similar to the case of MBR-PAC(2,000 mg/L).

Abstract

Reused cooking oil is the oil which is used more than one time and contains less than 25% (by weight) of polar compounds. Degenerative reused cooking oil is the oil which is used more than two times

and contains more than 25% (by weight) of polar compounds. Major raw material of fried foods is oil. Therefore, usefulness of consumed fried foods depends on the quality of cooking oil. When the oil is heated

up while cooking, chemical change occurs due to the reactions of hydrolysis, oxidation, and polymerization. These reactions cause degeneration of the oil, i.e. black color, rancid smell, lower smoke

point, bubbled, increased viscosity, and generation of toxic substances called polar compounds. This

substance can cause high blood pressure, heart disease, and coronary artery disease. Furthermore, the reused cooking oil also contains polycyclic aromatic hydrocarbons (PAHs) - toxic mutagens which can

cause cancer.
