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.

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.

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.

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.
To add Recalc Array
