I suggest you post to the softener forum if you want to discuss filtration. The guys there are experts in all aspects of water treatment and filtration.
I don't advise using any sort of booster pump.
That said, this is the right forum to discuss why your well is producing so much sediment or whatever that it is clogging your filter elements. However, you need to tell us more about the well, the pump, the water usage, what is clogging the filter, etc.
