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.chemical_addition_zo.ChemicalAdditionZOData.cost_chemical_addition` method. For full details on costing, see documentation for the :ref:`zero-order costing package<zero_order_costing>`.
