Thermal and Physical Data for Concentrated Brine from RO

Thermal and Physical Data for Concentrated Brine from RO

(OP)
I am seeking information on a NACL concentrated brine solution . Density, viscosity, vapour pressure & bulk modulus vs. temperature. Properties are required for a fluid with 25% by weight salt.ie density ~ 1200kg/m3. Data in SI Units preferred.

RE: Thermal and Physical Data for Concentrated Brine from RO

For practical purposes, the brine will be similar to a 25% sodium chloride solution.

The exact brine composition will depend on the raw water properties, but the sodium chloride solution will not be that far off. The ideal RO temperature used to be stated as 77 Degrees F, but the temperature may be slightly lower depending on the RO membrane application, but generally above 55 Degrees F.
