|- | On || Tickbox || This variable in used to turn the unit ON or OFF. If the unit is OFF, all feed will exit via the Brine outlet. |- | valign="top" rowspan="3" | Model|| Simple || User only needs to specify Yield and Overall efficiency. No setting of pressures. No sub-models can be used. |- | General || User can choose from several efficiency methods and specify the outlet pressures. Sub-models can be used. |- | MaxYield || User specified the limit for maximum permissible permeate recovery, as well as the efficiency required and outlet pressure. Several efficiency methods are available. Sub-models can be used.
Available from Build 139.31388. Includes the effect of concentration polarization if ConcPolarizationFactor > 1.0. |- | MinYield || Input || Only visible when Model set to MaxYield. Required minimum fraction of pure water in the feed which is recovered to the product stream. |- | MaxYield || Input || Only visible when Model set to MaxYield. Required maximum fraction of pure water in the feed which is recovered to the product stream. |- | SolidsTolInBrine / SolidsTol || Input || Only visible if Model selected is MaxYield . The maximum solids fraction in the brine stream.
Available from Build 139.31388. If set to zero, target is achieved when the least soluble solid is at 99% of its saturation index. |- | CPF.Reqd || Input ||Available from Build 139.31388. Concentration Polarisation Factor: The ratio of the salt aqueous mass concentration at the membrane surface to the bulk solution (due to mass transfer). For calculating the concentration, the solution volume is calculated using the selected SysCAD species model (it is NOT calculated by {{{TCE}}}). |- | YieldReqd || Input/Calc || User can specify this value when Model set to Simple or General. Required fraction of pure water in the feed which is recovered to the product stream. |- | valign="top" rowspan="3" | HeatBalOptions / HB.Options|| FixedT|| User can specify the final product temperature. |- | FeedT || The final product temperature will equal the feed temperature. |- | FixedHeat || No heat will be added or removed from the unit. |- | OperatingT || Input || Only visible if HeatBalOptions selected is FixedT. The required temperature of the product stream. |- | CalcProductsUsing{{{TCE}}} / CalcProductsUsingTCE|| Tickbox || This variable in used to turn the unit ON or OFF. If the unit is OFF, all feed will exit via the Brine outlet. |- | valign="top" rowspan="5" | EffMethod || colspan="2" font style="background: #ebebeb"| Only visible if Model selected is General or MaxYield |- | Overall || User can specify a single efficiency of removal for all non-water liquid species. |- | Individual Phase || User can specify an efficiency of removal for each individual liquid phase. |- | Impurity Frac || User can specify the fraction of impurities in the product stream. |- | Ionic Permeability || User can specify permeability of ions in the feed through the membrane. The ions are defined as the total ions after a complete breakdown of all species in solution, i.e. total sulphate will include that from H₂SO₄, MgSO₄, etc. H⁺, OH^-, and H₃O⁺ ions cannot be specified |- | EfficiencyReqd || Input || Only available if "Model is set to Simple", or "Model to General or Max Permeate Recovery and EffMethod is set to Overall". Required fraction of liquid species other than water that are recovered to the brine stream. |- | EfficiencyReqd.x || Input || Only available if EffMethod is set to Individual Phase. Required fraction of species in individual phase x (other than water) that are recovered to the brine stream. |- | ImpurityFracReqd / ImpFracReqd || Input || Only available if EffMethod is set to Impurity Frac. Required fraction of liquid species other than water in the product stream. |- | colspan="3" font style="background: #ebebeb" | Pressure Requirements (Only visible if Model selected is General or MaxYield ) |- | Prod.PressureReqd / P_Reqd || Input || Required pressure of the product stream. |- | Brine.PressDropReqd / PDropReqd || Input || Required pressure drop from the feed pressure to the brine stream.
