| Abstract |
| This experiment used to synthetic of tunneling wastewater with Biocube and fiber media. Filtration efficiency were operated at 0% of the compression rate. In addition, fiber media was changed to 0%, 15%, 30% of compression rate and 300m/day, 500m/day, 1000m/day of Lv in this period. Using of the filtration for treatment of the tunneling wastewater was compared filtration efficiency and backwash cycle of media. For characteristics of filter media, high quality treatment of media investigated compression and change of filtration efficiency. Also, high turbidity of tunneling wastewater examined spiked experiment. Fiber media backwash cycle was 4 times longer than Biocube, The smaller the compression ratio tended to be longer backwash cycle. Except for filtration rate of 1000m/day, removal of turbidity was exceeded 90%. |
