IMSDesign-2015: User Guide Getting Started

This intellectual property belongs to Hydranautics P a g e | 1

1. Get Started

Integrated Membrane System Design (IMSDesign) is a software that calculates the

throughput of a reverse osmosis (RO) plant. You can use IMSDesign to create a design for a

water treatment plant that uses the reverse osmosis process. Using IMSDesign, you can

create designs that can be implemented for plants that can be used for industries and cities.

IMSDesign is designed to calculate the throughput of an RO plant. IMSDesign allows you to

move water data through a series of stages. Each stage functions as an input for the next

stage. Depending on the results on all the stages, IMSDesign creates an analysis and design

that is most suitable for your RO plants.

To create the RO design, you must perform the following high-level steps:

1.1 Analysis and Analysis Save

This is the first stage where you compute how the raw water sample is treated. You can

enter the water analysis report values and evaluate the analysis by using techniques such

as water balancing, measure saturation levels, and pH equilibrium.

At the time of performing an analysis, you must enter values for the raw water report and

analyze its ion combinations.

Additionally, IMSDesign enables you to specify the ion and chemical composition of Feed,

Permeate and Reject water and save your analysis.

1.2 Design

This is the second stage in the IMSDesign RO design system. To perform this high-level

step, you can specify parameters such as permeate flow, recovery, membrane type, and

number of stages.

At the time of creating a design, you can specify the product flow and recovery, membrane

type, age, and number of stages. You can also specify rates of flux decline, salt passage

increase, sizing of a permeate desalting stage, addition of permeate back-pressure or an

inter-stage booster, or recirculation of the concentrate stream.

1.3 Calculation

This is the third stage in the RO design process. During calculation, IMSDesign calculates

and displays values for Power Requirement, Chemical Requirement, and Cost.

After you create the design, IMSDesign performs calculation. IMSDesign calculates the

product quality and determines if design limits have been exceeded.

Getting Started IMSDesign-2015: User Guide

2 | P a g e This intellectual property belongs to Hydranautics

1.4 Post Treatment

This is the fourth stage in the RO design process. IMSDesign allows you to add the

chemicals to the stream and treat permeate.

At the time of post treatment of your sample, you can define the permeate treatment

options and the resulting changes in ionic concentrations and pH. You can also analyze

calculations of cost and power requirements.

enter under Cations and Anions.

9. Balance the water sample calculation by clicking the underlined ions.



3.3 Balancing Water Analysis

After you enter the cation and anion values, IMSD calculates the Total under Cations and

anions respectively. IMSDesign considers the calculation to be balanced if Total under

Cations and Anions is equal. By default, the cation and anion levels in the raw water

sample are balanced, but the analysis values might not always show this balance. That is

why the Analysis screen allows you to balance the cation and anion levels by manually

adjusting the underlined ions. If Total under Cations is less than Total under Anions, use

the underlined ions under Cations to ensure that Total under Cations and Anions is

equal. If Total under Anions is less than Total under Cations, use the underlined ions

under Anions to ensure that Total under Cations and Anions is equal.

The following image displays unbalanced results, where the Total value for Anions is less.

You can balance the raw water analysis calculations by adjusting the SO4 or Cl values.

3.3.1 Using Underlined Anions

The following image displays unbalanced results, where the Total value for Anions is less.

To balance the anion and cation levels

1. To balance the calculation, click the underlined cations. In this example, click ca,

Mg, or Na to balance the calculation by adjusting the SO4 ions.

2. Click Save As, and in the Save AS dialog box, type a name for your analysis.

3. The application saves the file with .anax extension.

3.3.3 Understand Saturation Results

After you enter the raw water analysis values, IMSDesign calculates the saturation levels of

water compounds such as Ca3(PO4)2, CaSO4, BaSO4, SrSO4, CaF2, and Silica in the water

sample. You can see these values under Saturation on the Analysis screen. You can also

see other values such as Calculated TDS, Ionic Strength, Osmotic pressure, and Saturation

Index.

The following table lists the scenarios for which Calculated TDS and Ions are enabled or

disabled.

3.4 Add Custom Ions

If your analysis report determines the presence of additional ions specific to industries,

IMSDesign allows you to enter custom ion values, and evaluate the analysis again. For a

new or previously created analysis (.anax, .des, and .desx), you can add a maximum of 3

custom ions under Cations and 2 custom ions under Anions.

You can add the following custom ions:

Under Custom Cations, you can add Cu, Cr, Mn, Fe, Co, Ni, Mo, Ag, Al, Pb, Zn,

Ra and U

Under Custom Anions, you can add Br, I and S.

To add custom ions:

1. Start IMSDesign.

2. In the Project file group, click New to create a new project.

Click Open to open an existing project.

3. In the Options group, click Custom Ion. Three options appear under Cations, and

two options appear under Anions.



Note: Only the first custom ion list, and the respective mg/l and mg/l CaCO3

boxes under Cations and Anions are enabled. After you enter values for the first

list, the next custom ion list is enabled.

Figure 15 - Custom ions option

4. Enter the custom cation values in the mg/l box. IMSDesign adjusts the values in the

mg/l CaCO3 box accordingly. You can also manually update the values in the mg/l

CaCO3 box.

Note: You can set a minimum value of 0 and a maximum value of 50 for Cu, Cr, Mn,

Fe, Co, Ni, Mo, Ag, Al, Pb, Zn, Ra and U in the mg/l and mg/l CaCO3 boxes

respectively.

5. Enter the custom anion values in the mg/l box. IMSDesign adjusts the values in the

mg/l CaCO3 box accordingly. You can also manually update the values in the mg/l

CaCO3 box.

Note: You can set a minimum value of 0 and a maximum value of 50 for Br in the

mg/l and mg/l CaCO3 boxes respectively. You can set a minimum value of 0 and a

maximum value of 500 for I and S respectively.

6. (If required) Balance the analysis.

7. (If analysis is balanced) Click Save As, and in the Save AS dialog box, type a name

for your analysis.

The application saves the file with .anax extension.



3.5 Multiple Analysis

The Multiple Analysis functionality allows you to import multiple analysis to calculate a

blended analysis. After you open multiple analysis, IMSDesign calculates the average of the

aggregate values for each field. For instance if Temperature in Analysis 1 is 25 °C and for

Analysis 2 is 35 °C, the Temperature field displays aggregate value of 30 °C.

After you select multiple analysis files, the average of aggregate of Total under Cations and

Anions might differ. You can balance the blended analysis by manually adjusting the

underlined ions under Cations or Anions.

After you enter multiple analysis and their respective Flow values, IMSDesign calculates the

Total under Cations and Anions respectively. IMSDesign considers the calculation to be

balanced if Total under Cations and Anions is equal. By default, the cation and anion levels

in the raw water sample are balanced, but the analysis values might not always show this

balance. That is why the Analysis screen allows you to balance the cation and anion levels

by manually adjusting the underlined ions. If Total under Cations is less than Total under

Anions, use the underlined ions under Cations to ensure that Total under Cations and Anions

is equal. If Total under Anions is less than Total under Cations, use the underlined ions

under Anions to ensure that Total under Cations and Anions is equal.

Note: You can balance multiple analysis files of the same water type only.

1. Start IMSDesign. The Analysis screen appears.

2. In the Options group, click Multiple Analysis. The Multiple Analysis section

appears.

4.1.11 Add Recalc Array

The Average flux for the design depends on the water source, TDS, the permeate flow, and

the selected membranes. If the flux levels are not optimum, IMSDesign highlights them in

red. At the time of re-designing the array, the obtained average flux value might not be

optimum. For such scenarios, you can use the Recalc Array option to change the selected

array to such that it is appropriate for the values that you entered. The Recalc Array option

auto-calculates and modifies the entered values and displays the appropriate average flux

value.

Note: IMSDesign enables Recalc Array only if you select the first element type for the

corresponding pass and stage.
