Good day Eugene,

there has been a slight modification in the phase 2 of my research...

i am now requested to look for a good kinetic model for the degradation of substrates using ulva lactuca, not pig manure....

my plan is this, i will fabricate a batch digester feeding it with ulva lactuca...

from the mass balance of substrate (Ulva) i obtained an equation relating the HRT, substrate reduction and rate of substrate utilization via:

HRT = (Csin-Csout)/rs

where rs is the rate kinetics of utilization

Csin is the substrate in

CSout is the substrate out

HRT is the hydraulic retention time...

i would like to ask for guidance:

i will have one or more equation to represent rs (which can only be done by bacth experiments)

one is kC^{n}, then the next is the monod, then the third is the chen and hashimoto, and the fourth is a model that i derived myself, i was thinking that i will represent only the model that will give the best curve fit, am i right?
