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>`.
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.suboxic_activated_sludge_process_zo.SuboxicASMZOData.cost_suboxic_asm` method. For full details on costing, see documentation for the :ref:`zero-order costing package<zero_order_costing>`.
