== General Description ==

{{TPS - General Description | TPS=PHREEQC |UnitOp=Reverse Osmosis}}

=== Diagram ===

[[Image:RO Unit.png]]

* The diagram shows default drawing of the Reverse Osmosis unit with connecting streams.
* The physical location of the streams connecting to the unit is unimportant. The user may connect the streams to any position on the unit.
* When inserting a Reverse Osmosis unit into a flowsheet, the user may choose a different symbol from the menu.

== Inputs and Outputs ==

{{TCE RO Inputs Outputs|TCE =PHREEQC}}

== Behaviour when Model is OFF ==

If the user disables the unit, by un-ticking the ''On'' tick box, then the following actions occur:
* All feed material will flow straight out of the Brine outlet;
* No material will flow out of the Product or Vent outlets;
* No sub-models will be called.

So basically, the unit will be 'bypassed' without the user having to change any connections.

# '''[[Material Flow Section|QRxnUnmapped]]''' - Optional tab, only visible if ''ShowQRxnUnmapped'' is enabled on the [[#TCE tab page|TCE]] tab page.
# '''[[Material Flow Section|QBypass]]''' - Optional tab, only visible if ''ShowQBypass'' is enabled on the [[#TCE tab page|TCE]] tab page.
# '''[[Material Flow Section|QRxnBypass]]''' - Optional tab, only visible if ''ShowQRxnBypass'' is enabled on the [[#TCE tab page|TCE]] tab page.
# '''[[#MembraneInterface tab page|MembraneInterface]]''' tab - This tab displays the Output stream results including the amounts of each PHREEQC species present in the final mixture for the brine side of the membrane.
# '''[[#Product tab page|Product]]''' tab - Optional tab, only visible if ''CalcProductUsingPHREEQC'' is enabled on the [[#PHREEQCReverseOsmosis tab page|PHREEQCReverseOsmosis]] tab page. This tab displays the Output stream results including the amounts of each PHREEQC species present in the final mixture for the product side of the membrane.
# '''[[Material Flow Section|QFeed]]''' - Optional tab, only visible if ''ShowQFeed'' is enabled on the first tab page. This page shows the properties of the mixed stream as the feed to the unit.  If user has specified a required pressure in the unit, the mixed feed will be set to this pressure. This may cause the temperature of the mixture to change if the delta P is significantly different. 
# '''[[Material Flow Section|QTCEFeed]]''' - Optional tab, only visible if ''ShowQTCEFeed'' is enabled on the first tab page. The TCE feed is the actual feed to the RO unit.  The max recovery option works by removing water from the feed iteratively until we get the required solids in the reject.
# '''[[Material Flow Section|QTCEProd]]''' - Optional tab, only visible if ''ShowQTCEProd'' is enabled on the first tab page. The TCE Prod is the actual product from the RO unit.  The max recovery option works by removing water from the feed iteratively until we get the required solids in the reject.
# '''[[Material Flow Section|QFeedProdSide]]''' - Optional tab, only visible if ''ShowQFeedProdSide'' is enabled on the first tab page. 
#{{ShowQout|Prod|Product|139only=yes}}
#{{ShowQout|Brine|139only=yes}}
# '''[[Common Data Sections#Common Data on Info Tab Page|Info]]''' tab - contains general settings for the unit and allows the user to include documentation about the unit and create Hyperlinks to external documents.
# '''[[Links Table|Links]]''' tab, contains a summary table for all the input and output streams. 
# '''[[Audit]]''' tab - contains summary information required for Mass and Energy balance. See [[Model Examples]] for enthalpy calculation Examples.
