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 :py:meth:`~watertap.unit_models.zero_order.coag_and_floc_zo.CoagulationFlocculationZOData.cost_coag_and_floc` method. For full details on costing, see documentation for the :ref:`zero-order costing package<zero_order_costing>`.
