نرم افزار ROSA (طراحی سیستم های اسمز)

(TDS (Total Dissolved Solids به تمامی مواد جامد محلول در آب چه آلی و چه غیر آلی اطلاق می شود که معیار سنجش آن برحسب میلی گرم در لیتر یا ppm است که TDS آب آشامیدنی نهایتا تا مقدار ۱۰۰ppm می رسد.

 

روش های متفاوتی برای کاهش TDS در آب وجود دارد. یکی از اقتصادی ترین فرایندها برای تهیه آب آشامیدنی از آب های مناطق کم آب، روش اسمز (Osmosis) معکوس می باشد. اسمز معکوس روشی است برای تصفیه آب که توسط غشاهای نیمه تراوا و فشار هیدرولیکی، املاح را از آب جدا می کند و می تواند TDS را تا ۹۵ درصد کاهش دهد.

نرم افزار (ROSA (Reverse Osmosis System Analysis، ارائه شده توسط کمپانی DOW، نرم افزاری قدرتمند در طراحی سیستم های اسمز است و از ویژگی های این نرم افزار می توان به توانایی داشتن اطلاعات جزئی از آب خوراکی و قدرت محاسبات یونی طراحی هایی با استانداردهای دنیا و تخمین هزینه نیز اشاره کرد.

بنابراین با استفاده از این نرم افزار می توان طراحی هایی مطابق با استانداردها داشت و همچنین گزارشی کلی از ساختمان سیستم اسمز معکوس و هزینه های مورد نیاز را نیز ارائه داد.

نرم افزار ROSA Version 6.1.5
Release date: 12 June 2007
Build date: 23 May 2007
 The following issues have been resolved
– If a new case is added and the water information is carried over into the new case, it
appears that the same water type is defined for the new case (both on the Feed tab
and on the report), but the design warnings in the new case are triggered by water type
“RO Permeate SDI < 1” instead of the expected water type. Therefore, the report for the
new case may not give the appropriate design warnings (unless the expected water
type is RO Permeate SDI < 1)
– In the Overview report, in a 1-pass system with recirculation, the recirculation loop on
the diagram shows the arrow pointing downward (away from the feed line, suggesting a
bypass) rather than upward (toward the feed line)
– When opening a saved file that contains multiple cases, some of which include a
recirculation loop, the system drawing on the System Configuration tab in the user
interface may not always draw the line representing the recirculation loop when
switching between cases
– When quickly clicking the ROSA 6.1 shortcut icon more times than necessary to open
the program, a second instance of ROSA tries to open, but invokes an error and shuts
down
– An error occurs when the 2nd pass is eliminated and subsequently restored in a case
involving a 2-pass system with Pass 2 concentrate recycled to Pass 1 feed
– An errant line is drawn in the Overview Report diagram for pH adjustment in 2-pass
systems
– Errors occasionally occur when using the Conversion Utility to transfer ROSA
۵٫۴ projects to the ROSA 6.1 file format
– An error occasionally occurs when ion exchange softening is selected on the
Scaling tab

نرم افزار ROSA Version 6.1.4
Release date: 19 February 2007
Build date: 16 February 2007
 The following issues have been resolved
– If a .rosa project file that is an e-mail attachment is double-clicked, ROSA
sometimes terminates because the folder that it tries to open the file into does not
have write permission
o Reprogrammed to gracefully handle the error and inform the user that the .rosa
file must be saved somewhere outside of e-mail where write permissions exist
– Power and Specific Energy calculations in report do not reset when deleting a booster
pump
– Design warnings do not always display on the reports using the Chinese interface
setting
– Saving a file in the Chinese interface, then closing and re-opening the file, resets the
water type to RO Permeate SDI < 1 on the Feed tab in the interface, although the
intended water type still prints correctly on the reports
– Miscellaneous Chinese text labels are displayed in English
– When specifying ions in the Feed tab, switching to the Scaling tab to change
S&DI value, then switching back to the Feed tab where a concentration value is
entered/changed, the TDS value goes to zero
– Changing the dosing chemical type from acid to base gives an erroneous message
– The order of a few FILMTECTM elements in the combo box on the System
Configuration tab and also in the specifications table are re-ordered to the end of the
list when the water type is changed
– When a value is specified for Pass 2 feed pressure, the value will not clear after
returning to “Calc” mode
– Instability is sometimes observed regarding the Overview Report diagram
– If default units are set as metric, flow units on Recirculation Loops in the System
Configuration tab display as “gpm”, although the calculations and report are in the
correct metric units
– When a new case is added and water data is requested to carry over into the new case
the water type for the new case reverts to the default RO Permeate SDI < 1
 The following program changes have been implemented
– The report window automatically expands to the full-screen mode for easier reading
the window size can still be changed, minimized, or closed as desired
 Database changes were made to improve the modeling accuracy of seven
FILMTECTM elements

نرم افزار ROSA Version 6.1.3
Release date: 17 November 2006
Build date: 10 November 2006
 The following issues have been resolved
– Handling of several string and currency values cause an error
– Using a single quote (‘) in the project title causes an error when if the project file name
contains the same illegal character
– Opening a project file in which the recirculation option had been checked, but the
recirculation flow rate equals “۰” causes an error
– Changing the text in “Analysis by” or “Company Name” is not reflected on the
printed report until after the file has been saved
 The following program changes have been implemented
– Some system designs do not converge on a solution in 2000 iterations. In this
instance, a message will now be displayed, rather than terminating the program as an
error
– When a program error occurs, the user can now optionally also add descriptive
text that explains the actions taken leading up to the event. This text will be
included in the log file that can be sent to the ROSA project team for instant
analysis when the user chooses to send the error report
– If the ROSA application is installed on the root directory (c:\ROSA61), when
ROSA is opened, a message box will indicate that the program must instead
be installed in a subfolder and ROSA will close

نرم افزار ROSA Version 6.1.2
Release date: 7 July 2006

– Obstacles to database access cause errors on some computers, including
preventing ROSA 6.1 from opening in some cases
– On some systems with administrator restrictions that prevent write-access to
the root directory, an error is caused trying to write three temporary files
(FinalXML.xml, Rosa61CalcEngine.Log, and MyProject.xml)
– Opening multiple instances of ROSA to the “Project Information” input tab
causes an error
– Calculation of system recovery in a 2-pass system is not always correct
– Eliminating Pass 2 containing a recirculation loop causes an error
– A data-type conflict with date values causes a rare error
– Entering a value for blending that was too large invokes a message box that
creates an error
 The following program changes have been implemented
– A warning message is issued to the user if ROSA 6.1 is installed on the root drive
– The Overview Diagram in the “Report” tab is cleared when switching to a different case
 The following FILMTECTM elements have been designated as obsolete in ROSA
SG30-400 and SG30LE-430. These elements can still be selected to run projections
but a message alerts the user that the element is obsolete
 The following FILMTECTM element specifications were upgraded in line with

when it should be “Boron (B)”
– The number of elements is not properly transferred to the EVA spreadsheet
– Changing the value in a concentrate recirculation flow sometimes causes an error
– The file path is occasionally truncated when a file is opened by doubleclicking on a .rosa project icon, causing an error
– Opening ROSA with certain Regional and Language Options (including Finnish
Norwegian, and French) causes an error (Cast from string “-۰٫۰۰۰۴” to type
‘Double” is not valid)
– Adding/subtracting stages too quickly with the spinner control causes an error

نرم افزار ROSA Version 6.1.0
Release date: 5 April 2006
Build date: 4 April 2006
 The user interface is now available in two languages: English and Chinese. The
user interface language can be switched with the Options menu (however, viewing
the Chinese interface requires that East Asian fonts are installed)
 A custom Water Library that memorizes frequently-used water analyses has been
added when “Specify individual solutes” is selected in the Feed tab
 A separate window is opened to display the Detailed Report (and, optionally, the Overview
Report) so the report can still be viewed while making changes to the system configuration

of NaOH required for the pH adjustment will now be less
 New information is now available by hovering the mouse over components in the
System Configuration diagram
 The ROSA Project Converter utility has been added as an option in the File menu
 A bug that caused ROSA to display the same blended permeate value in the Detailed
Report on subsequent calculations has been addressed. It is no longer necessary to save
re-open, and re-run the projection to reset the value
 A bug that sometimes caused a new case involving iLEC products to yield a slightly different
feed pressure calculation compared to the original base case has been addressed

نرم افزار ROSA Version 6.0.1
Release date: 7 June 2005
Build date: 25 May 2005
 A patch was incorporated to address a rare issue caused by a random, unexpected change
to the system registry value that was intended to recall the coordinates for displaying the
ROSA window on the monitor. When this occurred, it appeared that ROSA would not start
or that the program was invisible even though it was listed as an open application on the
Windows® task bar, or sometimes resulted in Runtime Error 6. The patch causes the
ROSA window to open in the center of the monitor, ignoring the system registry value that
may be corrupt
