Abstract: Oil palm is an important economic crop of Thailand. Most of the planting areas are in Southemn part of the country where, as a result, many palm oil mills are established. Paim oil mill is one of the major sources of water and air pollutions in the area due to the characteristics of its wastewater which is high in organics and oil content making the treatment rather difficult. This research aims to study the application of ozone oxidation, anaerobic treatment, activated sludge system, and menbrane bioreactor to treat palm oil mill wastewater in combination. Results shows that the optimal ozone dose was 3,000 mg/hr with only 15 minutes duration to yield highest BOD:COD ratio change from 0.49 to 0.88. This high BOD:COD ratio indicates the appropriateness of the ensuing biological treatments. In anaerobic treatment, higher COD removal was found when the ASBR system was treating the ozonated wastewater compared to the non ozonated one. Biogas yield (L/gCOD) from the ozonated wastewater was approximately 30%
higher. However, the methane content of the biogas from the ozonated wastewater was 54.8% while it was 81.1% from the non ozonated wastewater. In the activated sludge system, COD and BOD removal were 62% and 79%, respectively, when treating non ozonated wastewater while it was as high as 81% and 88% in the membrane bioreactor. When the membrane bioreactor received wastewater from ASBR, COD and BOD removals were around 70% yielding effluent COD of 809 +- 51 mg/L. and BOD of 50 +- 5 mgL. Eficiencies in the removal of other pollutants in all the systems studied as well as the groups of microorganisms found in the activated sludge system and membrane bioreactor were reported.2552-01-01T00:00:00Zประสิทธิภาพการทำงานของระบบติดตามตรวจสอบแบบออนไลน์ในโรงบำบัดน้ำเสียของโรงงานอุตสาหกรรม

Abstract: The main objective of this study was to compare the measuring capacities of BOD/COD online analyzer with the standard methods used in laboratory. Meanwhile, to the measuring Spectrophotometry Analyzer and standard methods used in laboratory with the parameters analyzed in this study were BOD5, COD NO3-N and Suspended Solids (SS). The results showed that the online analyzer could not measure synthetic wastewaters which were not aerated, the error measuring of BOD5, and COD were over the acceptable ranges. The synthetic aerated wastewaters, concentrated between 0-100 0-200 and 0-100 mg/, gave error of 6.35 2.33 and 11.69 %, for BOD5 COD and SS, respectively. The Ministry of Industry Notice (2002) Issued Pursuant to Content Values of difference of BOD and COD not more than +15%. The results also showed that the reliable of measuring domestic wastewaters, effluent from palm oil industry and effluent from seafood industry were acceptabie. Ultraviolet absorbance could be used to estimate many parancters with different reliabities. Absorbance of 260 nm and 500 550 could be used for measuring COD and SS.2552-01-01T00:00:00Zการใช้กากตะกอนส่วนเกินจากระบบบำบัดน้ำเสียแบบแอกติเวเต็ดสลัดจ์ และกากขี้แป้งของโรงงานน้ำยางข้นมาทำเป็นปุ๋ยหมักอัดเม็ด

Abstract: This research study is about using industrial waste from latex rubber industry in southern Thailand for producing pellet organic fertilizer. Industrial wastes applied in this study are sludge from wastewater treatment plant and rubber latex lutoid. In the primary stage, the fertilizer gave C/N ration was very low, high moisture content and fine material, which affected to the slow mechanisam. But after 45 days, the product could reach the Thai organic fertilizer standard according to chemical parameters; N, P, K and heavy metal. However, it was found out that the organic fertilizer from those industrial wastes contained high concentration of Zn, between 0.40 - 5.23 percent by dry weight. Meanwhile, the
remaining Zn in the marigold, after 35 days applying as fertilizer to plant 1.5 months old marigold.2554-01-01T00:00:00Zการพัฒนาการท่องเที่ยววิถีไทยในพื้นที่เปราะบาง เพื่อรองรับการเปลี่ยนแปลงสภาพภูมิอากาศ

Abstract: The research program: Developing way of Thainess tourism in vulnerable areas in coping
to climate change was developed to find appropriate Thainess tourism model for tourism
communities, tourism entrepreneurs and related organizations can apply for using and planning
to develop tourism model in vulnerable areas in order to develop sustainable tourism. The results
from three research projects are as following.
1) The results from tourists revealed that majority of participants are female with aged
between 20 to 29 years. Most of them are single and hold a bachelor’ s degree. Most of
participants are university students and their average income is between 10,000 and 30,000 Baht.
The origin region of these participants are the Southern Thailand. The results of an evaluation
toward the potential of natural and cultural tourist attractions displayed that Muang district
obtained a potential in tourist attraction, accessibility, and amenities. However, Huy Yod district
had a potential to develop in tourist attraction. In terms of Pa Lien District (Sukorn Island), activities
and attraction were two main potentials, whereas Kan Tang District (Li Bong Island) revealed a
potential in tourist attraction and accommodation. To certain extent, Slow Tourism tends to
develop in a small countryside community with has an originated lifestyle such as Li Bong Island
and Sukorn Island. The outcomes of this study showed that Slow Tourism in each area should be
developed continually along with a good cooperation with the leaders and the representatives
of local communities and public and private sectors. The most important concept on Slow
Tourism in the context of Trang province is the development should not be rushed, rather to
sustain the nature and the local culture should be more emphasized as there two factors are the
main ways to cultivate the sustainable tourism in the area.
2) The results of potential assessment showed the biodiversity of aquatic animals, the highest
potential ecological resource in all indices and is the main profit for local people, at the average
value of 4.4. It could be the indication of the abundant food chain in Koh-Mak. The main economic
aquatic animal such as Plotosus canius, Heteromycteris hartzfeldii, Macrobrachium rosenbergii,
Metapenaeus brevicornis were mostly found. The local vegetation, the secondarily mostly found
at the average value of 4, were the conventional plant, e.g. sugar palm, cashew nuts, and Parkia
speciose, etc. the same kinds of bird found in Khu Khut Water Fowl Park were found at the
potential ecological resource of 3.7 the lowest average value at 1.6 was the community water
management. The results of potential assessment were presented to local people in the
community through brain storming activities. Eight tourism activities on two tourism routes, both
land and water tourism routes, were proposed for the development guideline. From the study,
the learning water tourism routes, were proposed for the development guideline.The learning of
local fishery was the highlight among the proposed tourism activities and rarely found at present.
The potential ecological resources were developed to be souvenir products. The result found
that crispy rice mixed with shrimp and hepatopancreas of Metapenaeus brevicornis shrimp
(control) has the most acceptance of sensory evaluation with statistical significant ( p < 0.05)
compared with other treatments. The developed product can use to be guideline for product
improvement that state the community identity by using marketing communication concept to
promote product sale.
3) The result topic of “Study of Thainess tourism route with low carbon conscious at Phang Nga
Province”, indicated the community-based tourism area in the context of natural resources, local
wisdom and culture. The routes of tourism activities are organized by the local community that
is awareness of the environmental impacts. The study area is Ban Sam Chong Nuea Community,
Takua Thung District, Phang Nga Province. The evaluation result has a high potential of 2.57,
suitable for low-carbon tourism activities. The guidelines for the development and management
by the local participation. The select activities for kearning and tourists to gain experience such
as food, the way of life with the Muslim community, social, cultural and environmental values in
accordance with the guidelines and the context of the community. The results of the study were
presented to the community through a brainstorming process, allowing formulating a new
alternative tourism in local.2564-01-01T00:00:00Z
