dc.description.abstractThe aim of this laboratory investigation was to determine the most optimal conditions to remove dye from two types of wastewater namely direct synthetic wastewater and wastewater from silk factories. The dye concentration tested had been 0.1, 0.2, and 0.3 g/L dissolved in the wastewater together with the adsorbate  in a ratio (v/v) of 5 levels being 1:8, 1:4, 3:8, 1:2 and 5:8. The Jar Test method had been applied. During the test procedures a sample of the wastewater was taken for every hour and the dye concentration in the sample was determined by using a spectrophotometer at a wavelength of 555 nm. The test procedure was interrupted after the dye concentration leveled of to a plateau indicating that an optimum of the removal of the dye had been achieved. The efficiency of dye adsorption had been measured in percent of the decrease of the dye absorption at the start of the experiment and at the optimal point of dye removal considering also the dye/adsorbants ratio used for each test run. The same procedure had been used for testing dye removal from wastewater derived from a silk factory at Tumbon Banchieng Amphoe Nonnghan, Udornthani province. From the factory wastewater also the indicators COD, SS and TDS had been determined. Analysis statistic were  percentage, mean, One way ANOVA and BonferroniThe optimal condition for dye removal had been achieved with a dye concentration in wastewater of 0.1 g/L with an adsorbate ratio of 5:8 and allowing an absorption  time of 13 hours by using carbon black. The dye absorption using carbon black as adsorbent was 80.66% and using rice husk was 80.15%. A dye concentration of 0.2 g/L with an adsorbate ratio of 5:8 resulted in a dye concentration reduction after a 9 hour’s test run of 70.25% for carbon black and 70.56% for risk husk. The results for 0.3g/L with an adsorbate ratio of 5:8 for an 8 hour’s test run had been 60.48% for carbon black and 55.25% for rice husk The efficiency of rice husk in removing dye from the wastewater of the silk factory with an adsorbate ratio of 5:8 and a 9 hour’s test run had been. The indices COD, SS and TDS from the factory wastewater proofed to be according to standards after the dye removal. The result of the experiment suggests that carbon black and rice husk are appropriate means to remove dye from wastewater originated from coloring  silk under conditions tested in this experiment before discharge wastewater to environment.en_US
