Generating and Understanding the RO Detailed Report

RO Detailed Report can be generated as shown on Figure 1.

Figure 1: Generation of Detailed Reports in WAVE

Detailed Report Components are given on page 2 of the report and are shown below.

Further details of the simulation results are given below.

Flows, stream concentrations and scaling risks are detailed per pass. More flow details are provided at the Stage level and Element level for each pass.

In case of permeate split, WAVE does not create an additional element; instead it ‘extends’ or ‘shrinks’ the adjoining elements so that the number of elements in the pressure vessel remains constant. The elements marked in the asterisks are thus virtual elements.

Solute concentration is given in a below table:

Costs are reported for the RO system as shown below.

The service water costs have two components:

Non-product feed water – this is water that the plant would have paid to get but would not be using (because it is discharged).
Waste water – this is water that the plant has to pay to remove from the premises

Even though in simple systems the non-product feed water and the waste water are the same, in more complicated systems they would not be. For instance, if extensive chemical cleaning is used in RO to maintain recovery, the non-product feed water cost would remain the same but the wastewater disposal cost would increase.
