Good Afternoon Mr. ...

Good Afternoon Mr. Ghadaksaz,
RO is not efficient for nitrate, nitrite, arsenic, fluoride removal. Rejection rate is 45% - 55%.
If this is a smaller RO, you can pretreat with specific anion resin to reduce the nitrate and fluoride.
Another option is to raise pressure to 100 psi (250psi if larger system).
Another option is mixed bed deionization post treatment.
Warmest regards,
