Dear Prof KV Raman.

This is an important factor ie sizing and design of RO Reject water parametrs.

If you desire RO water to be of least TDS ppm then the flow would be maximum, and this needs to be done by selecting the right operating pressure on the RO Membaranes.

If the process can have the maximum TDS ppm on Reject water released would be very minimum and hence the observance of higher salinity.

Here too the appropriate operating pressures are applied.

The above may be kept noted, for designing athe reject water-flows in a RO water-process.

Well wishes.
