ซึ่งมีค่า pH 6.73 ค่า COD 13,552 มิ

Which is the cod 13,552 ph 6.73 mg per liter. And the absorbance at 214 nm was 3.055, exceeding effluent standards prescribed. Therefore, treatment with alum precipitated initially by the amount of 20 grams of water remaining after settling the cod in 2177.84 milligrams per liter. And a reddish residue which the absorbance at 572 nm is 0.037 for treatment effect by absorbing charcoal cob. That resembles a small tablet. Using charcoal packed columns 1, 2,.5 g, respectively, and by adding activated carbon in wastewater Stirring 5 and 10 g, respectively, then the water through adsorption to ensure high quality that methods Stirring cob charcoal 10 g reduced cod. Most remaining 210 Make the water cod.17 milligrams per liter. In which the effluent standard. Accounted for 90.32%, and the percentage of the absorbance value decreased to 0.025. Accounted for 99 percent efficiency.However 18% ph value below the effluent standard. Seen that corn cob charcoal 10 g with comparable performance activated carbon that is 5 grams, corncob charcoal is effective in reducing the cod and the colors are less carbon and 97%, it was 90.34 percent.49%, respectively.

Which has a pH value of 6.73 13552 COD mg/l. And suck up the 3.055 light 214 NM, which exceed standard wastewater treatment so it is defined first by settling with alum doses 20 g. The water after settling with the remaining COD 2177.84 mg per liter, and the red-colored, which remains up to absorb light at 572 NM 0.037. So the treatment by adsorption by charcoal-corn that looks as small pellet by using a column contain 1, 2, 3. 5 grams, respectively, and how further dissemination in charcoal, boiled water for 5 and 10. Grams, respectively, and then release the water through adsorption to quality inspection, it was found that a disturbing way, charcoal-corn 10 g COD charges can be reduced as much as possible, with a value of COD. 210.17 mg/l. That is a benchmark in wastewater. 90.32% per cent efficiency in and suck up light reduced 0.025. Accounted for 99 per cent efficiency.18%, but with a lower pH effluent standards criteria. See that corn-efficient 10 g charcoal compared to charcoal charcoal 5 grams, kamman-efficient corn to reduce COD and color values is less than the charcoal man. 90.34% and 97%.49%, respectively.

which is 6.73 pH COD value 13,552 mg per liter and the value of the light absorbing 3.055 at 214 NM which exceed standards set by the water reservoir and the first treatment by precipitation with สารส้ม amount of 20 grams, water after precipitation with COD rest 2177.84 mg per liter and a sorrel color remains, the light absorbing 0.037 at 572 NM, the absorption by the treatment with the corncob charcoal tablets that are small by using the column containing the coin-1, 2,5G in the order and the way to stir up the coals in the terminal 5 waste water and 10 G in the order and then bring the water absorption through the way to verify the quality found that stirring substances. Corncob charcoal 10 G can reduce COD most water COD remaining value is 210.17 mg per liter, which is thought to be effective in the standard drain Ajarn % and absorbing light Ajarn reduced performance at 99 per cent.18% lower than pH criteria values, but there are standard SEWER COLLAPSE apparently corncob charcoal 10 G is a comparison with the 5G, the activated carbon charcoal corncob performance in the lower values and COD color settings less than coal, winter Ajarn and 97 percent.49 % respectively
