Membrane Design (RO)

In this lecture you learn:

1. Stage and array in  RO/NF,  2. Pressure Drop and its Effect on Membranes, 3. Osmotic Pressure and Reverse Osmosis, 4. Mass Transfer, 6. Separation mechanism, and 7. Mechanisms of Solute Rejection in RO/NF.

In this lecture you learn:

Step 1: Consider Feed Source, Feed Quality, and Required Product Quality

Step 2, Determine the flow pattern

Step 3, Select Membrane and Element Type

Step 4, Selection of design flux

Step 5, Calculation of module number

Step 6, Calculation of Pressure Vessel number (Nv)

Step 7, Calculation of recovery (S) %

Step 8, Calculation of stages

Step 9, Determine the ratio between stages (R)

Step 10, Balance the Permeate Flow Rate

In this lecture you learn:

The parameters that have to be evaluated include:

1.Permeate flow rate

2.Water flux in reverse osmosis

3.Solute rejection and salt passage

4.Recovery %

In this lecture you learn:

one of the important fundamentals that have to be considered in membrane design is energy and sustainability considerations. In this lecture, we go on the course with this topic.

In this lecture you learn:

In a  case study,  for drinking water supply from groundwater,  nanofiltration is needed because groundwater has polluted with Callisto Herbicide.

Step 1. Determine the minimal membrane area that is necessary to treat the feed volume flow. To do this step.

Step 2. Calculate the investment and operation costs for the plant.

Step 3. Relate the values which were calculated in 2) to the produced water (per m3).
