Reverse Osmosis Pilot
Description:
Reverse Osmosis Pilot : Important parameters for this process :
- The important parameters for the membranous processes are :
- The flow speed on the membrane in the recycling loop (where the salt solution is concentrated) ;
- The pressure given by the pump at the input of the membrane ;
- The permeability of the membrane.
- The temperature.
- The efficiency at 10 bars (16 bars) is only of 5% (15%) maxi, for this reason, we recycle the supply water which concentrate itself.
- The pilot is powered either by the electric cabinet of the Tournesol module, either by the electric network, according to the low load threshold of the batteries.
At the end of the production, we will be able to analyse the energy consumed by the network and the energy consumed by the panels.
Teaching Objectives of Reverse Osmosis Pilot
- We will calculate the permeability of the membrane and we will verify its performances according to the following hydraulic and chemical parameters:
