A study on activated carbon from bagasse and charcoal adsorption efficiency in decolorization and COD of sugar factory wastewater from rajburi sugar co., ltd

The current time activated Carbon spaciously have been used in the process of wastewater Treatment and Air Pollution Treatment because of it can absorb various materials such as colors smells and organic materials both in the wastewater or air pollution In this research the researcher interest to study the activated carbon from bagasse as become more quantity in the country to use for reducing the pollution of wastewater at Sugar Company and recycling the leaving materials. This study is the Experimental Research being divided into 2 kinds of charcoal: 1) synthesizing activated carbon from bagasse 2) charcoal. The three contents of waste water: 10 50 and 100 percent are used for analyzing and testing at three periods of time: 30 60 and 90 minutes. The example of the wastewater were analyzed the color and COD. The using activated carbon from the bagasse with the content of wastewater at 10% shown that it could not absorb the color differently at every periods of time the color remained lower than 5 Pt-Co and it could reduce more COD at the more periods of time. At the content of waste water 50% shown that the more using time for absorbing the color the quality of absorbing become lower (10 15 and 20 Pt-Co) but it became more reduce COD while the absorbing the color at the content of waste water 100% found that when used the more time quality of absorbing the color became lower (25 30 and 35) while the quality of reducing the COD became increase. The charcoal at the content of wastewater 10% its’ absorbing color was 5 Pt-Co at the all periods of time but the result of reducing the COD was increase: 4300 4000 and 3800 respectively. As the testing the content of waste water at 50% shown that the more using the time its’ quality of absorbing the color became lower while the quality of reducing the COD became decrease: 7330 6500 and 6030 respectively. As studying the content of waste water 100% found that the more using the time for treatment the waste water its’ quality became decrease but it could more reduced COD. The comparison between the activated carbon from bagasse and the charcoal shown that the activated carbon from bagasse can absorb the color better than the charcoal at 0.25 Pt-Co and could more reduce COD than the charcoal 43.5 % by average at the content of waste water 10%. While the waste water 50% the activated carbon from bagasse could more absorb the color than the charcoal at 55% and can more reduced the COD than the charcoal 19.34% averagely. For the content of waste water 100 % the activate carbon from bagasse could more absorb the color than the charcoal at 54.17% and reduced the COD 7.83% by averaging.

The study of nutrient components in co-composted sludge, from serm suk co.,ltd. applied on brassica chinensis growth
The study of nutrient components in co-composted sludge, from serm suk co.,ltd. applied on brassica chinensis growth

The study of nutrient components in co-composted sludge from Serm Suk Co. Ltd. applied on Brassica chinensis growth had the objective to reduce the amount of waste from beverage processing which the factory did not eradicate properly. This experimental research helped reducing the problem of sludge eradication by using the sludge as a fertilizer. The experiment was divided into 2 sets. 1) The dried leaves and garbage 2) The dried leaves garbage and sludge. All sets have 60 . Collect data every 5 days. The growth rate of each part was measured including the height of trunk and number of leaves. Found that in the set 2 was the best nutrients the values are as follows organic matter is 30.64% (w/w) carbon is 17:11% (w/w) the ratio of carbon : nitrogen is 22:1 total nitrogen is 0.80% total phosphorus is 0.43% and pH is 6.35. It also affected to the growth of the Brassica chinensis better than set 1 and set 3. The growth of the highest level at average at 7.7 cm and the average number of leaves at 4. This set was the best ratio for growing Brassica chinensis and reducing the waste from factory as well.

Efficiency of vetiver grass variety songkla 3 cultivated in domestic wastewater treatment with floating platform technique
Efficiency of vetiver grass variety songkla 3 cultivated in domestic wastewater treatment with floating platform technique

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

The removal efficiency of oil and grease from  cafeteria wastewater by using chitosan from shrimp shell
The removal efficiency of oil and grease from cafeteria wastewater by using chitosan from shrimp shell

Chitosan natural cationic polysaccharides is synthesized by deacetylation of chitin one of the major structural elements of exoskeleton of crustacean shrimps. Due to its combination of many unique properties such as no toxicity biocompatibility and biodegradability chitosan has been widely used to adsorb fat and heavy metal absorbents. The present study was undertaken to demonstrate that chitosan extracted from shrimp shell wastes had ability in fat and oil adsorption. In the process 50% chitin in shrimp shells was first obtained and converted into for 25% chitosan through demineralization deproteination and deacetylation process. The highest adsorption performance at 72% was achieved at the chitosan sample at the condition composed of 0.6 g chitosan agitating in 400 mg/L of synthetic water comprising of fat and oil shaking at 90 rpm/min for 10 min. and thus equilibrating for 15 min. at room temperature. Its fat and oil removal efficiency was a effectively close the with that of commercial chitosan (86% and 85% oil and grease removal efficiency). The synthetic chitosan revealed 68.42% adsorption efficiency in treating in water sample with 570 mg/L of oil and fat from the effluent in the canteen at Rajamangala University of Technology Phra Nakhon North Campus. Therefore from overall the chitosan prepared from shrimp shells could possibly be further developed for future application in oil and fat removal from waste water treatment system.

Studies on the use of okara to replace wheat flour in stoopwafel were done forto select appropriate amount of okara analysis nutritional facts and sensory evaluation. The stoopwafel basic recipe of magda (2559) was applied by using okara replaced wheat flour. The replacement percentages were 30 40 and 50 of the weight of wheat flour. The experiment is planned by Randomized Complete Block Design ( RCBD) . Then to evaluate the sensory quality in appearance color odor taste texture and overall preference with 9- point hedonic scale. The panelists were 60 lecturers and students from Home Economics Technology Rajamangala University of Technology PhraNakorn. Sensory evaluation showed that the okarastoopwafel prepared from 30 percent okara obtained the highest overall acceptance score from the panelistson all sensory attributes exceptedtesteattributes which there was no significant difference in three amounts of okara. The nutritional facts found thatfat moisture total energy and energy from fatwere slightly increased but protein and carbohydrate were decreased which compared to control stroopwafel ( 100 percent wheat flour) . In addition to 96 percent of consumer acceptedthe okarastoopwafel
