Assumption: 10" 5 micron filter

I'm finishing up a homebuild RO system and want to better understand what to expect concerning a pressure change from the feed inlet to the 10" 5 micron filter and from the filter to the high pressure pump. I assume that with a new and clean filter the pressure readings won't be significantly different. However, as the filter does its job and becomes clogged, what should I expect for a pressure delta between the infeed and outfeed ports of the filter canister?

The system is currently programmed to shut off if pressure drops below 30 psi on the outfeed side of the filter. I have no idea what to expect for a pressure build up on the low pressure (infeed) side of the filter as it becomes clogged. Will it go above 50 psi and still provide a 30 psi outflow? Will it need to go higher? The low pressure pump has a max psi of 75.

Thanks in advance for any information.
