Abstract
RBC media 3 dimensional bergerigi is one is the biological treatment which consists of a series of kontaktor played the way the medium shaped 3 dimensional jagged. With a 3 dimensional jagged media then the surface area will be even greater. Design parameters of for RBC's organic loading (Rs) and the substrate constants (Ks) done in batches or in a State of steady state most still with media type 2 dimension. So this research is done in batches in determining the design parameters of organic loading (Rs) and the substrate Constants (Ks) of the RBC 3-dimensional media with the analysis of kinetic process. This research was also conducted to know the percentage of allowance for RBC media 3-dimensional organic content on COD, TSS and the influence of chemical parameters that DO, pH and temperature. This research was conducted by variation concentration of COD with influent (So) = 6420 5126 mg/l, mg/l (So * 80%), 3854 mg/l (So * 60%), 2470 mg/l (So * 40%), 658 mg/l (So * 20%), and the sampling time is 6 hours, 12 hours, 3 hours, 24 hours, 30 minutes.. From research conducted retrieved results which best COD concentration stage of 96,21% for COD at the COD variation of 3854 mg/l and TSS concentrations of 90,96%, in 20% of waste. Temperatures kept between 25 C to 30 C, the pH of the effluent waste tofu is netral operations know as to the value of 6 to 8, DO most quickly emerged that at the time of sampling of 6 hours with a 20% waste. Parameter design on RBC media 3 dimensional jagged to organic loading (Rs) of 8.4895 g/m2 day and substrate Constants (Ks) of 1107,16 mg/l jam
