Crude model of sludge water aeration cf. https://www.plctalk.net/qanda/showthread.php?t=131415

Usage

As shell command

python fopdt.py [--plot]

As Python model

import matplotlib.pyplot as plt
import fopdt
aeration,inflow,model = fopdt.FOPDT32().init_steady_state()
daeration = aeration * 1e-4
dinflow = inflow * 1e-4
o2_data = list()
for i in range(1024):
  model.model_step(1,aeration,inflow)
  o2_data.append(model.cells_pg32[-1]/model.pv_factor)
  aeration += daeration
  inflow -= dinflow

plt.plot(o2_data)
plt.show()

Manifest

fopdt.py

• Python module fopdt with class FOPDT32
• Requires module numpy
• Require module matplotlib to plot
