- Abstract
The tofu industry is processed from soy extract which mostly is a household industry producing waste with high protein and carbohydrate content. Waste produced by washing process, boiling, pressing give burden of high enough contamination because without going through the processing process before disposed of environment. For that it needs a simple and simple technology that can be utilized for the processing waste of industrial tofu. One simple technology that can be applied to waste treatment by combining aeration and biofilter methods to reduce levels of BOD, COD, TSS and pH improvement. Type of quasi experiment research, pre-post test research design. 90 lt plastic containers and equipment, aerators, water pumps, hoses, brickshaped media. This research was conducted with variation of 10Cm, 20Cm, 30Cm and 3 days, 6 days and 9 days contact time. Measurements of BOD, COD, TSS and pH parameters were performed before treatment and after treatment on day, third, sixth and ninth. The result of the measurement is compared with the quality standard of waste water based on PerMenLHRI no. 15 Year 2014. Data were analyzed univariat and presented descriptively. The result of Kruskall Wallis statistic test showed that there was no difference of BOD, COD, TSS and pH levels on the thickness of the 10 cm, 20 cm and 30 cm fine brick media on the 3rd, 6th and 9th days. The most effective reduction of BOD at thickness 10 cm day 6 decreased by 64.27%, decrease of COD level on the thickness of 10cm brick and 3rd day by 58,84%, decrease of TSS by day 3rdebesar 81,73%, To change pH according to the quality standard between 6 - 9, then on the thickness of brick liniment media on the sixth day has been effectively improve pH to 8.1. This research can be used as one of alternative waste treatment and this research can be
