modellower_layer
Layer below influent of Otterpohl`s SC model
Extends from WWSC.SCParam, WWSC.SCVar.
Information
This class models the layers between the influent layer (feed_layer) and the lowest layer (bottom_layer)
of an ASM2d secondary clarifier based on Otterpohl.
Hydraulic and sedimentation flux (mass exchange in same direction) with above and underneath layer.
Sedimentation flux is calculated based on two sedimentation velocities
(for macro and micro flocs) and the omega correction function by Haertel.
