Optimization of Total Solid (TS), Temperature, and Rumen Fluid Content During Biogas Production from Cattle Manure Using Response Surface Methodology

Water hyacinth is one of the rapid growth rate water weed in Rawapening Lake. Water hyacinth contains high hemicellulose which can be used for biogas production. This.,research aims to.,know.,the optimum value of total.,solid (TS), C/N.,ratio and microbial consortium for the biogas production with SS-AD from water hyacinth. The variations used for TS are 15%, 27.5%, and 40%, for C/N ratio are 20, 35, and 50, for microbial consortium are 3%, 6%, 9%. Sixteen reactors of 2 litres volume used with the variations inside are determined by Central Composite Design in Statistica software. Results of the biogas production are then analysed using Response Surface Methodology for optimization. Based on the analysis, the optimum value of TS is in the range of 5%-10%, value of C/N ratio is 32.09, and microbial consortium is 7.26%. Reactor 10 with the TS 5.45%, C/N ratio 35, and microbial consortium 6% has the closest value to the optimum value. The production rate of reactor 10 then analysed using Polymath 6.0. The constant kinetics rate of biogas (U) production rate is 1.88mL/g TS day; maximum biogas production is 108.41 mL/g TS; the minimum.,time to form the biogas is 8.87 days.

In this study, marine sediment (MS) was successfully used as a source of methanogenic bacteria for the anaerobic digestion (AD) of chicken manure (CM). Using MS showed high production in liquid and semi-solid conditions. Even in solid conditions, 169.3 mL/g volatile solids of chicken manure (VS-CM) was produced, despite the accumulation of ammonia (4.2 gNH3-N/kg CM). To the best of our knowledge, this is the highest methane production from CM alone, without pretreatment, in solid conditions (20%). Comparing MS to Ozouh sludge (excess activated sewage sludge) (OS), using OS under semi-solid conditions resulted in higher methane production, while using MS resulted in more ammonia tolerance (301 mL/gVS-CM at 8.58 gNH3-N/kg). Production optimization was carried out via a response surface methodology (RDM) model involving four independent variables (inoculum ratio, total solid content, NaCl concentration, and incubation time). Optimized methane production (324.36 mL/gVS-CM) was at a CM:MS ratio of 1:2.5 with no NaCl supplementation, 10% total solid content, and an incubation time of 45 days.
