Pulp and paper industry has grown steadily. At the same time Papermaking process at each step, it would be a waste. And environmental impact in the form of sludge. And in the form of waste water from the production process. Wastewater from pulp and paper industry has increased volume. The waste water from pulp and paper, as mentioned above, there are fly ash, a waste from the production process in the combustion process. This research aims to reduce the color and COD in the waste water of paper mills by developing a natural treatment using fly ash for improving soil and absorbing toxins in water treatment. pulp and paper mill waste. The study showed. For the experimental batch that fly ash can help in healing the color and COD of up to 91.00 percent and 39.39 percent respectively in the experimental continuous-flow, packed materials crop lien. The wastewater treatment system, GRID and wetland GRID found that the removal efficiency of turbidity and COD, which increase in fly ash into the sewage system. nature that are appropriate in the treatment of 3 hours at the appropriate ratio of ash to the soil, it is 1:60 and powerful color therapy. COD in waste water by up to 72.58 percent and 75.00 percent respectively, effective treatment is better than artificial wetland system significantly.
