Generation and Understanding of Summary report

Once all the required inputs are in place in the Ultrafiltration Tab, the RO system can be simulated by clicking on the “Summary Report” Tab to generate the Summary Report and the “Detailed Report” button as shown in Figure 1.

In the Summary report the RO system diagram and some key output are described as shown below.

The RO system is described in a Pass level Process Flow diagram as shown below. The streams are numbered for clarity. This would look different from the RO/NF/ROSC Process Flow Diagram in the Reverse Osmosis Tab (which describes the process at the Stage level).

RO - Summary Report

These tables provide an overview of the RO/NF/ROSC system.

Summary Report - RO - Pass

There are several components to note from the Overview Table

  1. The Chemicals added to adjust pH and prevent scaling
  2. In the case of more complicated designs (e.g. involving permeate split or feed bypass), there would be asterisks on the Stage and Pass respectively that mark where the split or bypass happened. The user is then urged to look at the RO system diagram and flow tables for clarification.

Summary Report - RO Flow Table Stage Level

The RO Water Quality Table provides a convenient summary of the process by describing the feed and permeate compositions for all passes and permeate split streams, as well as a blended final product stream.

WAVE provides Design warnings as well as potential solutions. The Pass, Stage and Element at which the warning is triggered is identified:

The scaling risk is summarized in the table below. In the RO Scaling Table, WAVE would flag % saturation values > 100, LSI >0 and S&DI >0 by changing the color of the number to red. However, only one of LSI or S&DI would be displayed in the top panel. The display is based on the concentrate characteristics.
