The concentration, the concentration of the ro, the concentration of the ro permit can be calculated, can be calculated by, can be calculated by multiplying, multiplying the nacl, multiplying the nacl rejection rates of, rates of both the nf and ro, the nf and ro processes with the initial nacl, processes with the initial nacl concentration, initial nacl concentration.

Since the nf process, since the nf process has a rejection rate, has a rejection rate of 45%, it will remove, it will remove 45 % of the nacl, 45 % of the nacl leaving, leaving 55 % of the nacl, leaving 55 % of the nacl in the feed water, in the feed water.
01:36
The ro, the ro processes will then remove, processes will then remove 95 % of the remaining nacl, remaining nacl resulting in a very low, resulting in a very low concentration, very low concentration of nacl, of nacl in the ro permit, ro permit...
