Getting Started

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


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.

1.5 Start IMSDesign This section describes how you can start IMSDesign. To start IMSDesign: 1. Click Start > All Programs > Hydranautics IMSDesign.Net. The Setup window appears.

Analysis


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.

Analysis


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.
