need filter system for very fine silt
I'm on a well that produces a lot of sand and fine bentonite silt; it goes through the standard small whole house filter as well as a Lakos separator and gets into my appliacnces. The only solution suggested by local plumbers is an expensive ($1500 installed) multi-stage filter sort of like a water softener as I understand it
The smallest off the shelf filter I can find is 2 microns, but it cuts water flow considerably. An expert at the state engineers says my silt is probably smaller than 1 micron.
Is there a simple, less expensive filter system I can use?
