Hello! Can anyone help me on how to solve our problem with regards to our RO?
We are using a PA membrane and a 4-2 pass configuration. The Primary pressure is still the same but suddenly the final pressure went high. Usually final press was at 65psi ti 75psi but after we have passed 30ppm hardness, the final pressure went to 110psi. We are dosing NaOH for pH.
Many thanks
