1. Introduction to Winflows 4.06

The Winflows software is an intuitive and user-
friendly simulation program that allows users to
quickly design simple or complex reverse
osmosis (RO), nanofiltration (NF), and
electrodeionization (EDI) systems. The software
provides exposure to Veolia’s spiral wound RO
and NF membranes and E-Cell* EDI stacks along
with extensive cartridge filters products as well as
pre-engineered RO and NF systems.

Winflows version 4.06 features the following updates:

General Program Improvements:

• Improved flux convergence when running RO projection at higher temperatures.
• Resolved a mass balance issue on high sulfate feedwater under low pH conditions.
• Improved validation and warning on feed pH excursion for an expanded range of membrane types (PA RO,
PA NF, CA).
• Improved user interface which now indicates the RO unit that has the Specify Feed Pressure option activated.
• Revised Pump Specification menu and Pump Summary to the final power consumption after adding an ERD.

Membrane Product Updates:

• Addition of new highly fouling resistant brackish water Durafoul RO1 Series elements for challenging wastewater
applications
o Durafoul RO1 is available under BW RO FR → Durafoul
• Improved the pressure drop performance for the H Series 400 sqft elements to reflect the recent manufacturing
advances:
o Includes: AG-400 H, AG-400 FR H, AG-400 LE H, and AK-400 H
• Improved the salt rejection to 99.65% for the legacy AG series elements:
o Includes: AG2540TM, AG4040FM, AG8040F, AG8040F-400, AG8040F-440, AG4040FM FR,34,
AG8040F-400 FR,34, AG2521TM
• Consolidated and updated the BEV-RO Series and BEV-NF Series element with cage outer wrap:
o Includes: BEV-RO-CG, BEV-RO-ULE-CG, BEV-RO-LE-CG, BEV-NF-CA-CG
• Updated the HL Series elements to provide a more accurate projection in municipal applications:
o Includes: HL2540FM, HL4040FM, HL8040F-400
• Revised the MgSO4 rejection for the Industrial NF1 Series elements to reflect the actual element performance:
o Includes: IND NF1 4040F35, IND NF1 8040F35
• Updated the pressure drop parameters of many of the RO and NF series elements to allow a more accurate
pressure drop projection especially in low pressure applications
• Removed obsolete elements discontinued in 2023

E-Cell EDI Module Updates:

• Updated to reflect the expanded flow ranges of the existing 3 Series of E-Cell EDI stacks. The updated flow limits
are as follows:

Winflows Installation Guide

o MK-3MiniHT: The new flow range is 0.5 to 1.6 m3/h (2.2 to 7.0 gpm)
o MK-3PharmHT: The new flow range is 1.6 to 5.4 m3/h (7.0 to 23.8 gpm)
o MK-3: The new flow range is 1.6 to 4.54 m3/h (7.0 to 20.0 gpm)
• Updated to align with the current operating temperature and pH limits for E-Cell EDI:
o Temperature range: 4.4–40 °C (40-104 °F)
o pH range: 4 to 11
• Co-current option is now available on the RO-EDI flowsheet to allow a lower EDI feed pressure down to 3.1 bar
(45 psi)
• Updated Concentrate pressure drop calculations
• Added Concentrate Pressure validation which now raises a warning on negative values
• Added Voltage validation which now raises a warning when above the voltage rating of the selected DC power
supply (rectifier)
• Fixed a mapping error with the EDI Import & Export feature, i.e., “Open Water Analysis & EDI" and “Save Water
Analysis & EDI”
• Added PRO E-Cell EU to the dropdown list for the E-Cell EDI systems

Cartridge Filter Product Updates:

• Addition of Filterplex.Z (FP.Zs) Z.plex depth filter to replace Muni.Z (MUNI.Zs)

The user is assumed to possess basic knowledge of RO and NF system design principles and know the required
performance of the system under consideration. This tool is user friendly, highly reliable, robust and intuitive in designing
of RO and NF systems as compared to other competitive tools.

2. What you need to install Winflows 4.06

Your computer must have one of the following supported operating systems:

• Windows 7 or later

Disk Space Requirements:

• 80 MB (for Winflows program)

• 850 MB (for .NET Framework runtime)

Required disk space to download the Winflows program:

• 65 MB to download the program

• 116 MB to download the .NET Framework

Display Resolution:

• Winflows works best in a screen resolution higher than 1024 x 768

3. Installation of Winflows 4.06 Application

If you currently have an older version of Winflows (e.g., Winflows 4.05) ensure the application is closed. Next, download
the setup package from https://www.watertechnologies.com/resources/winflows. The package is in a compressed zip
file. Extract the zip file to a folder on your computer (e.g., C:\WinflowsSetup\). The following files will be extracted:

• Winflows 4.06.msi
• Read Me First Winflows 4.06.txt
• setup.exe
• DotNetFX45 [Note: this folder will only be there if you download the setup with .NET framework 4.5 runtime]

First time users may need Administrative rights as .NET Framework runtime will be installed on the local machine by the
Setup Wizard.

Please follow the step-by-step guide below to successfully install the Winflows program to your computer.

Winflows Installation Guide

Step 1: Run Winflows 4.06.msi by double clicking on it. A Setup Wizard will appear on the screen.

Step 2: If the local machine does not have the .NET Framework installed the Setup Wizard will automatically do
so. You may need Administrative rights or the help of a system administrator in order to install Winflows.

Step3: In the License agreement for Winflows as shown in the below screenshot, user needs to accept and
select “I Agree” option and click on the Next button to proceed.

Step 4: The Setup Wizard will now prompt you for the location where you wish to install Winflows on your
