การศึกษาการบำบัดน้ำเสียจากการย้อมผ้าแบบเคลื่อนที่โดยใช้ถ่านกัมมันต์จากกะลามะพร้าว
The dyeing industry both of business size and household size where the remaining water from the dyeing process is dumped into pipes and flows into natural water sources causing sewage problems. Therefore a column type wastewater treatment system has been developed by using a filtration system along with an adsorption system. The materials used to treat the wastewater from dyeing are gravel sand charcoal from wood and activated carbon from coconut shell. The study was conducted on the synthesis activated carbon from coconut shell using for color and molecules adsorption. The amount of activated carbon from coconut shell was varied at 200 400 600 and 800 g applying with filter media and other adsorption materials taking 1 hour to treat the wastewater from dyeing. The parameter using to measure water quality consisted of color value pH suspended solids conductivity turbidity value COD and TKN to indicate the water quality before and after treatment evaluating the efficiency of the wastewater treatment system. The best ratio that can treat the color is the formula containing 800 g of coconut shell activated carbon. It was able to treat the color equal to 5.94 SU or 99.43 percent compared to the wastewater before treatment.

This research is to study the efficiency of treating wastewater from dyeing fabric by the ozonation process. By using rutile TiO2 coated plastic media to catalyze. Which uses O3 generators with a capacity of 2.62 - 3.10 g/hr. By studying the factors that affect the treatment efficiency of COD and color such as the pH of the water used in the treatment at pH 3 pH 7 and pH 11 the initial COD concentration of 100% 50% and 25% which have values in the range of 100 -320 mg/L. O3 exposure time 120 min. From the study it is found that the efficiency of reducing the impurities in wastewater by the ozonation process in the pH 11 state the COD concentration at 50% can reduce the COD. And the maximum color is at 33.3% and 90% from the 550 ADMI color intensity with a COD of 180 mg/L. For the study of the efficiency of reducing the impurities of wastewater by ozonation process together with 2 g. of TiO2/1 L. of wastewater in the condition of pH 11 concentration COD Beginning at 100% with the ability to reduce COD values And the maximum color is at 40% and 80% of the 270 ADMI color intensity with a COD of 190 mg/L. The amount of O3 suitable for treatment has an average value of 0.0374 g/min./10.5 L. of wastewater. The duration of O3 exposure in both processes has a similar approach to the efficiency of COD and color treatment when increasing the duration of O3 exposure.

Dye effluent treatment with photocatalytic technique and adsorption process had an objective for studying the combination process between Titanium dioxide and activated carbon from dye effluent. The dye effluents were prepared from the direct dye reactive dye acid dye disperse dye and basic dye. The effluent dyes from the completely dyeing process at 1 % owf initially. All of dye structures were azo. From the study direct dye and reactive were successfully using combination process between photocatalytic technique and adsorption process whereas disperse dye favored in adsorption process. However acid dye and basic were ignored in this experiment cause of they were a bit of dye concentration in their effluent. The optimum condition for direct dye was 10g/l Titanium dioxide for 6 hours and 5 g/l activated carbon for 6 hours continuously. Reactive dye was performed in continuous condition as 10g/l Titanium dioxide for 6 hours and 10 g/l activated carbon for 6 hours. Disperse dye was the particular process in adsorption by activated carbon 15 g/l for 4 hours. It was summarized that the treatment of photocatalytic technique and adsorption process were upon on the type of dye.

This research studied the efficiencies of ceramic membrane filtration from industrial asphalt for dyeing wastewater treatment by forming a ceramic membrane in a diameter of 6 cm height of 2 cm. An appropriate proportion of industrial ashes: kaolin: sodium hydroxide solution mixed with sodium silicate solution was 46:18:36 at 800 ° C. For the properties analysis of ceramic membrane made from industrial ashes found that a shrinkage value compression resistance and density water absorption value and permeate flux were found 3 percents 0.6 Kilonewtons per cubic centimeter and 1.93 grams per cubic centimeter 45 percents 8.61 milliliters per square centimeter per minute respectively. Structural surface by a scanning electron microscopy was found that the porous inside of material was closely aligned together. Moreover precipitation of synthetic wastewater by using industrial ashes could help to increase the efficiencies of dyeing wastewater treatment. From the experiment it was found that the precipitation of synthetic wastewater with industrial ash was 94 percent filtration efficiency. On the other hand the efficiencies of synthetic wastewater treatment without precipitating of industrial ashes found only 69 percent. Moreover this research offers a new option for industrial wastes utilization.

This research has studied the treatment of municipal wastewater with shoe soles as a supporting media for Sequencing Batch Reactor. The objectives of this research were the conditions to for optimize growing Photosynthetic Bacteria (PSB) and understand the treatment efficiencies of municipal wastewater treatment with PSB in Sequencing Batch Reactor (SBR). Three types of shoe soles were applied in this research composed of rubber shoe soles neoprene and EVA and the control without shoe soles. The experimental factors included the essential parameters such as BOD COD SS MLSS MLVSS Phosphorus and Ammonia-Nitrogen. F/M Ratio was adjusted at 0.13 and hydraulic retention time (HRT) was at 5 days. The results indicated that the removal efficiencies of SBR with rubber shoe soles in terms of BOD COD SS phosphorus and ammonia-nitrogen were 87% 80% 94% 53% and 68% respectively. The removal efficiencies of SBR with Neoprene shoe soles in terms of BOD COD SS Phosphorus and Ammonia-Nitrogen were 89% 81% 95% 20% and 73%. The removal efficiencies of SBR with EVA shoe soles in terms of BOD COD SS phosphorus and ammonia-nitrogen were 91% 86% 95% 56% and 74%. The removal efficiencies of SBR without shoe soles in terms of BOD COD SS phosphorus and ammonia-nitrogen were 84% 79% 93% 86% and 67% respectively. The treated wastewater was rather clear low content of suspended solids and no malodor. From overall results the treatment of municipal wastewater by anaerobic sequencing batch reactor with different types of shoe soles was not significant for wastewater treatment efficiencies by anaerobic with any 3 types among of shoes soles can be efficiently applied for municipal wastewater treatment.
