Hello,

SW30HR-380 is the best solution in terms of rejection because it's not low energy, so the pressure is higher and the salinity in the permeate lower but you need more modules because of the surface (380ft2).

SW30HRLE-400i and SWHRLE-440i is the same membrane (high rejection, low energy) the only difference is the surface (400 or 440). The pressure will be lower than HR380 (about 10-15 bar depending on the characteristics and temperature of the water) but the salinity in the permeate higher due to the lower pressure.

So if you need a higher rejection (e.g. for Boron) is better SW30HR-380 if you want to save energy SW30HRLE-440i.

Regards

Thanks.

In your opinion, fouling is more probable in which of the membranes? Why?
