This unit model is formulated as a single-input, single-output model form. See documentation for :ref:`single-input, single-output Helper Methods<siso_methods>`.
Electricity consumption is calculated using the constant_intensity helper function. See documentation for :ref:`Helper Methods for Electricity Demand<electricity_methods>`.
Costing is calculated using the :py:meth:`~watertap.unit_models.zero_order.fixed_bed_zo.FixedBedZOData.cost_fixed_bed` method. For full details on costing, see documentation for the :ref:`zero-order costing package<zero_order_costing>`.
