- class qsdsan.sanunits._crop_application.CropApplication(ID='', ins: Sequence[AbstractStream] | None = None, outs: Sequence[AbstractStream] | None = (), thermo=None, init_with='WasteStream', if_material_loss=True, loss_ratio=0.02)¶
Recovery nutrients in the recycled excreta (energy not recovered) based on Trimmer et al.
- Parameters:
if_material_loss (bool or dict) – If material loss occurs during application.
loss_ratio (float or dict) – Fractions of material losses during application (if if_materiloass is True).

- property loss_ratio¶
[float] or [dict] Fractions of material losses during application. If a single number is provided, then it is assumed that losses of all Components in the WasteStream are the same.
Note
Set state variable values (e.g., COD) will be retained if the loss ratio is a single number (treated like the loss stream is split from the original stream), but not when the ratio is a dict.
