PEMANFAATAN LIMBAH AMPAS TEBU DENGAN MENGGUNAKAN HCl SEBAGAI AKTIVATOR UNTUK MENGURANGI DAMPAK LINGKUNGAN DARI LIMBAH INDUSTRI TAHU

Abstrak

The research aims to determine the effectiveness of active carbon from sugarcane bagasse with activator substance of  HCl  in  decrease  the  value  of  COD  and  TSS  and  than  in    increase  the  value  of  DO  and  pH  in  tofu  liquid waste.The optimum condition of decrease the value of COD and TSS and also increase the value of DO and PH in tofu liquid waste is circulation time at 12 hours of fixed bed reaktor. The results of  the research show that decrease the value of COD from 123,7 mg/L to 41,6 mg/L or 66,37 %,  decrease the value of TSS from 335 mg/L to 103,8 mg/L or 69,1 %,  increase the value of  DO from 1,86 mg/L to 7,6 mg/L or 75,52 % and increase the value of pH from 3,53 to 4,66.
