Fly ash, a waste residue from the burning of lignite. To obtain thermal energy for use in pulp and paper.
This paper is to study the possibility of using fly ash as an adsorbent for color removal and COD in the wastewater industry, Pulp.
and Paper Experimental results BATCH found that the use of fly ash, 14 g water, 50 ml can effectively treat Paint.
Percentage: 91.00 and COD of 39.09 and exposure time of 3 hours, efficient removal of 21.79. COD and
57.10 percent, which forms the adsorption of fly ash is consistent with the Freundlich equation Digby. At the same time The fly ash mixed with clay.
The efficiency of color removal and COD best weight ratio 1:60, and the results of continuous flow. By using columns and a line through the
center of a 5 cm high, 30 cm packed gravel, coarse sand, 9.6 cm 4.2 cm 2.8 cm sand and fly ash soil mixture ratio of 1:60, which was divided into two sets, the first set of water samples. The outflow from the column every 15 min.
to measure the color and the COD series 2 samples of the water are left stagnant in column 3 dry and retesting. The results showed that
the release of water stagnant in the column for a period of 3 hours, effective treatment, color and COD over the release of water from the column continued.
In the experiments using a filtering technique in this subset. Small This will take measures 51x51x54 cm rectangular plastic tray containing plant material, such as a column experiment with planting two species of cattail and grass on each pickup. Then the wastewater treatment and discharge of waste water trapped in the body for 3 hours, and dry results indicated that the purpose of planting vetiver effective way to treat wastewater better pickup at the plant. Cattail You pick the grass is effective in the treatment of color and COD percent and 82.07 percent. 84.61 respectively The pickup is being planted cattail effective in the treatment of color and COD percent 64.53 percent and 53.84 respectively, which adding fly ash to join the crops that provide efficiency of treatment, color and DC. Oh, well above the ground, only 25 percent and 37 percent, respectively.
