6.1 Computer-aided design
A software was developed by Samer (2010) to plan and design biogas plants, specify the
dimensions of the different tanks (raw slurry tank, liquid organic matter tank, digester tank,
secondary digester tank, and residue storage tank), and compute the amounts of
construction materials (iron rods, cement, sand, and gravel) required to build the concrete
constructions. Furthermore, the software is able to calculate the capital investment and the
fixed costs, the variable costs, and the total costs. Figure 18 shows the user interfaces of the
input and output data windows.
