Primary clarifier module

Import

from asm2dmodel import primclar

Class

PrimClar(PAR)

Parameters

• PAR: primary-clarifier parameter vector, length 4

  • PAR[0]: sec2_perc

  • PAR[1]: TSS_removal_perc

  • PAR[2]: inorganic_factor

  • PAR[3]: inorganic_factor_P

Functions

outputs(u, PAR)

Split a 26-state ASM2d influent vector into a 52-state output vector.

Output structure

The returned vector has length 52:

• y[0:26]: overflow / primary effluent

• y[26:52]: underflow / primary sludge

Notes

This module is an algebraic primary clarifier for the 26-state ASM2d stream interface. Soluble states are passed through, while particulate states are separated according to the clarifier parameters. It is intended for use before the biological reactors.
