This unit model is formulated as a single-input, double-output model form. See documentation for :ref:`single-input, double-output Helper Methods<sido_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.electrocoagulation_zo.ElectrocoagulationZOData.cost_electrocoagulation` method. For full details on costing, see documentation for the :ref:`zero-order costing package<zero_order_costing>`.
