Comparison between WAVE and ROSA

WAVE is based on the legacy DW PS software called ROSA (which was described in the first edition of this book) but there are several key differences as described in Table 10.2. Some of the key differences reflect the multi-technology nature of WAVE. For instance, users can simulate the use of RO permeate or concentrate for backwash, front flush or CIP (Clean-In-Place) purposes using WAVE. 

The Toray DS2 RO system design software has all the features of the earlier version plus many new innovative and useful features for basic and more sophisticated RO designs such as two pass designs incorporating energy recovery devices, recycle options, partial and spht permeate collection, flux balancing using permeate back pressure, interbank boost devices, etc. 

The main input screens are accessed from the upper left menu tabs, as follows  

Start Screen Here is where the designer can select to use the Template design option or Create a New Project. In addition there is a Quick Start option to use as a reference document. This narrative will follow the Create a New Project route to construct an RO design projection. Click on Design a New Project to advance to the next screen. 

Project Screen This screen allows the user to enter unique project information. Minimum data required is project identification and engineer s name (or designer s name/initials). Next, click on Create Project to proceed to the next screen. Feed Data Screen At this point it is useful to select the engineering units desired. Click on the Unit tab to select
