aquakin.operational_cost_index_bsm2(aeration, pumping, mixing, sludge_production, carbon, methane, heating)[source]#

Full BSM2 OCI (Gernaey et al. 2014):

OCI = AE + PE + ME + 3·sludge + 3·carbon − 6·methane + max(0, heating − 7·methane)

Energies in kWh/d; sludge and carbon in kg/d; methane in kg CH₄/d. The methane credit and the methane-offset heating term reward biogas recovery. Sums the itemized contributions from bsm2_oci_terms() (the single source of the weights).

Parameters:

  • aeration (float)

  • pumping (float)

  • mixing (float)

  • sludge_production (float)

  • carbon (float)

  • methane (float)

  • heating (float)

Return type:

float
