reginit_bsm2

Initialization file for bypass control, KLa values and carbon flows related to the activated sludge reactors 1-5.

All parameters and specifications are based on BSM1 model. This file will be executed when running bsm2_cl.py, bsm2_ol.py or bsm2_olem.py.

QBYPASS

QBYPASS = 60000

Flow rate threshold for bypassing (type 2 splitter). Everything above this value is bypassed to the effluent [m³ ⋅ d⁻¹].

QBYPASSPLANT

QBYPASSPLANT = 1

If 1, all of the bypass flow is bypassed to the activated sludge reactor system, and not to the plant effluent.

QBYPASSAS

QBYPASSAS = 0

If 1, all of the primary clarifier effluent bypasses the activated sludge reactor system and goes to the plant effluent.

QTHICKENER2AS

QTHICKENER2AS = 0

If 1, all of the thickener effluent goes to the activated sludge reactor system, none goes to the primary clarifier.

QSTORAGE2AS

QSTORAGE2AS = 0

If 1, all of the storage tank effluent goes to the activated sludge reactor system, none goes to the primary clarifier.

KLA1

KLA1 = 0

Default KLa (oxygen transfer coefficient) value for reactor 1 [d⁻¹].

KLA2

KLA2 = 0

Default KLa (oxygen transfer coefficient) value for reactor 2 [d⁻¹].

KLA3

KLA3 = 120

Default KLa (oxygen transfer coefficient) value for reactor 3 [d⁻¹].

KLA4

KLA4 = 120

Default KLa (oxygen transfer coefficient) value for reactor 4 [d⁻¹].

KLA5

KLA5 = 60

Default KLa (oxygen transfer coefficient) value for reactor 5 [d⁻¹].

CARB1

CARB1 = 2

External carbon flow rate to reactor 1 [kg(COD) ⋅ d⁻¹].

CARB2

CARB2 = 0

External carbon flow rate to reactor 2 [kg(COD) ⋅ d⁻¹].

CARB3

CARB3 = 0

External carbon flow rate to reactor 3 [kg(COD) ⋅ d⁻¹].

CARB4

CARB4 = 0

External carbon flow rate to reactor 4 [kg(COD) ⋅ d⁻¹].

CARB5

CARB5 = 0

External carbon flow rate to reactor 5 [kg(COD) ⋅ d⁻¹].

CARBONSOURCECONC

CARBONSOURCECONC = 400000

External carbon source concentration [g(COD) ⋅ m⁻³].

QSTORAGE

QSTORAGE = 0

Default flow rate from storage tank [m³ ⋅ d⁻¹].

QW_HIGH

QW_HIGH = 450

Upper limit flow rate for waste sludge Q_W [m³ ⋅ d⁻¹].

QW_LOW

QW_LOW = 300

Lower limit flow rate for waste sludge Q_W [m³ ⋅ d⁻¹].

T_OP

T_OP = 35 + 273.15

Operational temperature of the anaerobic digester [K].
