modelfeed_layer
Influent layer of Otterpohl`s SC model
Extends from WWSC.SCParam, WWSC.SCVar.
Information
This class models the influent layer of an ASM2d secondary clarifier based on Otterpohl.
It receives the wastewater stream from the biological part (feed).
Hydraulic and sedimentation flux (mass exchange in opposite directions) with above layer
and hydraulic and sedimentation flux (mass exchange in same direction) with underneath layer.
Sedimentation flux is calculated based on two sedimentation velocities
(for macro and micro flocs) and the omega correction function by Haertel.
