This unit model is formulated as a pass-through model form. See documentation for :ref:`pass-through Helper Methods<pt_methods>`.
The constraint used to calculate energy consumption is described in the Additional Constraints section below. More details can be found in the unit model class.
Costing is calculated using the cost_coag_and_floc method in the zero-order costing package. See documentation for the :ref:`zero-order costing package<zero_order_costing>`.
